Re: Dies after hitting bumps
Well guys, I'm not really sure if I can drill/grind the bulge out. I was looking today and it looks like I'd hit the brass tube that the bystarter's needle goes into. Does anyone have any other ideas on fixing this?
Otherwise I'll have to start looking for an oem replacement.

The bystarter tube can be pressed out from behind (the carb bowl side).Well guys, I'm not really sure if I can drill/grind the bulge out. I was looking today and it looks like I'd hit the brass tube that the bystarter's needle goes into. Does anyone have any other ideas on fixing this?
MN is land of 'food on a stick' Link for food on a stick. We've had good food at parties inspired from MN.
Try a post in Wanted/For Sale a want for a carb body top. Hot parts are found there, but not yet on a stick.

Re: Dies after hitting bumps
How do I get the tiny c-clip out to be able to push the tube out?

Re: Dies after hitting bumps
Have they held up well?
Also how do I tell if I have a nb50, nq50, etc.? or are they all the same?

Your carb is an NQ50 type, the bystarter is on the other side for an NB50.

Opps, It's an E-clip. It's sittting right above the beveled lip on the top of the brass tube.

Re: Dies after hitting bumps
I cant give a full report on the bystarter because the scoots are put up for the winter now but I did buy one of these and it seemed to work well, I have not had a chance to test a true, hands off, cold startup and there is some shimming required to get the retention half-moon to hold it down. You have to remove the cover too.

I dont ever remember seeing an e-clip down there and I dont see one in your pic???
I'd just take a small round file or dremel and take the bump out from the inside, patch any holes created from the outside. Try not to tear anything else up and clean very well afterwards.

Re: Dies after hitting bumps
Clem, thanks for the advice. I have access to a nice drill press so I was going to go that route, but only if I got the brass emulsion tube out. To get the brass tube out I gave it a few taps with the back end of my screwdriver and it popped out.
I don't know what the thing in the bottom of the tube is, or what it is for.

Re: Dies after hitting bumps
I looked through more than a half dozen carbs w/o finding a clip and don't recall any clips on dozens of other carbs.
There is a detail on the casting looking like your posting. Pats fiche was reviewed, there is no replacement part installed into the bottom of the bystarter recess.
Also, made a comparison between your posted photo vs a pic of the same angle of a carb in the mouse garage. Our carb bodies appear the same.
Question: Was the black part you posted an actual component within your carb?

Re: Dies after hitting bumps
I guess I just haven't been able to get as clear of a look as you got in your pictures mouse. To me it looked like a clip or something but I guess it is just the casting that I'm seeing. thanks for the higher quality pictures mouse!
As far as the other picture you compared to mine, on your carb by chance is there a mark from a bolt like the bottom pic in my post from the 19th? On my carb I figure that the wall was thin enough for the casting to be pushed in causing that bubble. Mine definitely has a mark from too long of a bolt, and that's what I think cause mine to do that.
let me know mouse.

Re: Dies after hitting bumps
Hi mitsukid124,
You are correct in diagnosis and that you see a carb close to yours. The bystatrter air valve posted is definitely tagged by an improper bolt. Thanks for pics of issues you found, your thread will be helpful for future membersAs far as the other picture you compared to mine, on your carb by chance is there a mark from a bolt like the bottom pic in my post from the 19th?

Re: Dies after hitting bumps
Well I finally figured this out. It was the dent in the choke bowl causing my issue. I had to replace the carb with a used one. Now she runs perfect!!!
Thanks for the help you guys. Hopefully this will help people in the future.
