94 Honda Elite SR50 help

[RavinRace]

I purchased this moped off craigslist a few years ago for $125 bucks. It is in pretty good shape but didn't run. I finally got it to start but it would not stay running and would die. It is currently torn apart and I am stuck. I think it is the carb but I could be wrong. Any advice on what to do or attempt to do would be greatly appreciated.

You're probably right, it is likely the carburetor is dirty and glazed inside with varnish from evaporating fuel. Takes some careful cleaning and inspection to get it right. Often it takes several times to get fully cleaned. You give us very little info to help you find the problem, but from what you've said, the diagnosis is clean it.

Yeah I don't really know much about it. So I will tear it apart and clean everything really well and let you know if that fixes the problem. I think I would like to eventually mod it but I'd like to get it in running order before that so I don't waste my money. If this carb is not fixable what would be an upgraded carb that works for it?

Okay so I tried starting it and it will run and immediately go full throttle even though I do not turn the throttle and then it will die. What is causing that? I have taken the carb off and now and am in the process of cleaning it.

Sounds like its leaning out, so air leak of some sort. Check where carb connects to intake, intake to block (reed cage area). Crank seals. Ive also had a bike were i turned handle bars to right an it would rev cuz my throttle cable was pinching..

When you re-install the cable and slide back into the carburetor, be sure the slide is going in easily-do not force it. Before you do that, inspect the slide to see if there are scratches on the side, it would indicate that you have installed it incorrectly before. TIP: The bevel on the bottom if the slide faces the air box side. Then be sure the idle adjustment is backed out so that the slide is not open more than a sliver. The other causes of a scooter starting up at wot are, as mentioned, LARGE air leak, or the cable is out of adjustment, or, the slide and/or carburetor is incorrect for you scooter. Posting up some pics is always helpful........as there may be other issues not yet revealed.

Alright so that was a quick fix. Turns out the slide on the throttle cable in the carb was put in wrong. Put it in right, set the idle screw and it runs like a champ now. Will post some pictures up after I get it all painted and cleaned up. Any suggestions on where to start on modifications? And does anyone have the bottom left long trim piece that runs along the foot pad? I am in need of one. That is the only plastic piece that is damaged.

Best bang for your buck if probably a new variator for starters. Great improvement over stock.

Glad for your success...
I appreciate people who reply with the problem they found.
It helps many more people who are smart enough to read the forum.
Thank you sir...
Oh yeah, place an ad for the parts you want instead of leaving it in your thread to die without notice.
