Got the replacement carb rebuild kit in the mail today, almost every part in it was different than the first kit I got and most of the parts wouldnt fit and the ones that did fit didnt work http://cgi.ebay.com/ebaymotors/_W0QQcmd ... MEWNXQ3aIT
buy this kit at your own peril hahhaha the jet in this kit is a 68 and the float and needle valve dont fit only thing that is worth using is the float bowl gasket. I said to * with it and ordered the 21mm oko with intake kit from autotech335 on ebay and a oil pump plug so now I am playing the waiting game again I found a foodservice thermometer that measures up to 550 so I can at least get an idea of how hot she is running. installed the main emulsion tube and matching needle from the china kit but still cant accelerate past 15mph checked the temp at the head only around 150, the temp under the metal shield on the exhaust was 250 after i revved her on the stand for 15 or 20 mins

Got my 21mm oko with CT manifold with 4 reed intake today had to go work on a computer so I didnt get to really work with the new setup till late this evening then while hooking it all up I had to run back and forth working on my dads computer....its a nightmare finally got the throttle cable hooked up and everything put back together and tried to start it with no luck. checked compression again and spark is good. The plug was wet and i tok the carb off at the rubber and there was gas puddled between so I figure I need to adjust the needle and check the float height etc maybe a smaller pilot or even maybe too much oil. It got dark on me so I had to quit before I really got to do anything but get it assembled so I am gonna do my research tonight so I am prepared to tune tomorrow

Hey - thanks for the heads up on that carb kit. I recognize the parts as being for the 'clone' carbs being sold for the Elite SA50 and others. An obvious clue from the photo on your ebay link is

Float valve is two part - threaded brass seat, and needle.
Float itself has a metal tab, this is bent to adjust float height (unlike Honda's pre-set all plastic float)

Stay away from those kits guys

[Mystic]

yea that kit really is garbage unless you feel like taking hte dremel to certain pieces well I think i have got my Eve dialed in alright for the time being. I fooled with it all day without much luck and my fuel line i hooked together because i didnt have a long enough piece had a leak around the coupler allowing air in soo i went to the hondaman to get some fuel line and some jets. They didnt have any singles and couldnt or wouldnt order any. wanted me to buy a pack of 4 of each size and charge me for each jet in the pack of 5 different sizes and same with the pilots. He was like 90 something so far for jets and I about fell out hahha the website said it was 2.97 for a pack not for each one in a pack soooo I had to work with what i had till I can order something. the 103 hex the oko came with broke off when i tried to take it out go figure so the only one i had was a small round #95 luckily it seems to work but havent gotten it to wot under load and dont plan to for a little while longer at any rate. the pilot was supposed to be #40 but it is stamped #42, i had an old 38 that has seen its day and it seemed to be too small or half clogged up couldnt get it to idle for s***. so I have the 42 pilot and 95 main with the needle one up (5 slots on the needle) bogs in the middle and on the bottom so I figure my pilot is a tad bit too big. I think my main problem last night was I had an oz too much oil in the gas since i didnt drain the tank from the gas i put in with the pump still installed and i mixed 32:1 in the jug when i put the plug in sooo idle temps around 140, anyone know a cheap quick place to order some assorted jets or anyone have some for sell? maybe 85, 90, 95, 100 main and 35 38 and 40 pilot ?

Why don't you try the folks you obtained the OKO carb from, or you could try these folks; http://www.treatland.tv - really fast and inexpensive shipping. I have very good experience with them. GL!

yea i have seen those kits from several different places, i just dont have the money to buy all those jets that i am not going to use right now. i will probably order a 40 idle and 90 and 100 main from some random site and go from there. I am going to try to ride her a few miles tomorrow and if she rides alright with acceptable temps i will just wait till i get some extra cash and order the slow and main kits was kinda hoping someone had some extras

The pilot jet has nothing to do with idle.

[Mystic]

"Motor won't idle and idle set screw is ineffective. Try leaning out the air screw by turning it counter clockwise a quarter turn at a time. If the air screw has no effect, install a leaner pilot jet "

What circuit feds gas to the engine at idle??? the air mixture screw helps the pilot circuit get the right amount of air for idle and take off acceleration, if the pilot is too large you get too much gas at the lowest rpm. the idle screw, air mixture and pilot control idle up to 1/4th throttle so what you are saying is

[Mystic]

Furthermore, my swap build runs unlike what you said a few days about how I couldnt get my stuff to even run. I dont see any builds you have done lately other than all those stock Aeros. I put this thing together from pieces all over the world so I cannot be a complete idiot, positive feedback is accepted but your help is not required I just like talking about what I have done and what other people are doing, I am not begging for assisstance I am doing just fine without some know it all * face chiming in with some below the belt crap shot. You and maddog must be * buddies, you both try to tell people they are wrong but what works for you is not going to work for everyone else. A combination of alttitude, humidity, parts combinations, etc determine jetting so there is no set standard for what it SHOULD be unless everyone used the exact same setup, same gas and oil, and had the same potato chip up their *. It wouldnt be so bad if what you were saying was right but its not. We all cant be right 100 percent of time and neither can you but give a b**** a break

definately need a smaller pilot. took her for a spin to the gas station about 15 mile round trip. from 15 to 40 she sounded smooth as silk with a steady rumble of the muffler, I really like how she sounds the sound is richer than the stock carb, the sound was more treble than bass. After acceleration if i come to a stop she goes dead 4 out of 5 times and doesnt like to accelerate back to 15 without bogging out. If its not the size of the pilot that matters what else can I try to improve acceleration from idle to 1/4th throttle other than the air screw...you can only richer or lean it out so much. I will fiddle with the pilot some today to see if there are any changes. Would heavier weights work? I am thinking if the engine goes to a higher rpm before it engages the back wheel it will already have had to accelerate past the rough spot in my jetting, does that sound logical?

[dun rite]

do a plug chop at idle. will tell you if to lean or rich

[Mystic]

thanks dun rite, i am going to try a little bit of tuning today with what i have. I have a 38 and 42 pilot. Since my problems so far are mainly idle to 1/4th I am going to take it step by step. Have been reading all the carb tuning articles again just to refresh. mark my throttle at positions and start at middle clip on needle without the main jet in like some of the articles suggest that way i can isolate my problem i checked the float hiigth from factory last night and it was a bit high so I set it as best i could with my card board cutout method. Should the measurement be at the highest point on the float where it is rounded or the flat spot where it the plastic connects with the metal?

[Mystic]

well the float height was definately off I can get the engine to idle alright at the proper air screw range but at around 2 or so turns out and idle for about 5 to 10 mins still produced and oily blackish ring on the spark so either i still havent got my float adjusted or the pilot is a tad rich. I guess i will take it back off and verify the float height and change to the 38S pilot i have and do the pilot test again and see what results i have with it. guess it wouldnt hurt to scrub my plug clean either Whoever assumes that tuning any carb was easy for anyone can kiss my * lol I know a plug chop at idle isnt necessarily completely accurate but I cannot afford a tach and a temp gauge. I think a tach would help me tremendously at this point but no sense crying over spilt milk. Hopefully i can get to town today to put money on my card to pay for some jets I should have bought the jet kits with the carb but after spending 135, 50 dollars added too that seemed overkill until after the fact. I need to sell some s*** Any offers on a original red accessory glovebox with the tabs for 84-86 Spree or a spree windshield with mounting hardware?

weeeelllpp....I deceided to change the contra spring in my clutch today since I havent gotten around to doing it have had it sitting for a few weeks as well as yellow clutch springs. I figure i will wait on the clutch springs to see how it is going to perform with the 7g weights and 1500 center spring once i get the carb dialed in right. Got the clutch spring changed pretty easy but i had to take the kicker cover off and the drive face to get the thing back on with the belt. I noticed my variator was closed with wear primarily on the farthest edges so I slide the variator out and wouldnt you know...somehow 2 of the rollers had gotten caught and wedged at the outside of the ramp so my vari was staying at high gear I imagine that is why my take off has been almost nonexistant till i get the rpms up, fine on the stand but with load ...*. Its drizzling rain so I didnt try to start it didnt want to get rain in my carb with that free flow filter so I imagine from all the research I have done reguarding the variator and clutch that this has been my primary reason for low end power loss because the variator couldnt adjust to compensate. Will know for sure after it stops raining but the forecast is rain today and tomorrow. I sure hope I can go for a ride without it dieing at stop and go picks up quicker than it has
