Walbro carb...which one?

[cityevader]

I've read numerous references to Walbro carbs being used. I've tried googling them to see what bolt spacing they have, but no luck. There's quite a few to pick from, but no listed bolt pattern (my 70cc has approx 40mm spaced manifold bolts).

Anybody have a model number to help me out with?

I do recall someone mentioning the model number on this web site....don't remember who or where.

I would still PM Easy Rider to find more info, I think I read somewhere that some mod's have to be done for it to fit.

I feel your pain...I do!
Searching like crazy has gotten me very disappointed!
Even stopping into a few small engine shops got me down, as they can apparently only look up parts on a "by-model" basis. Like such and such log splitter or trencher or weed whacker needs such and such carb... no dimensions or specs or bolt spacing.
SSSIIIIIIIIIIGGHHHHHH!!!!!!!!
I think I'll PM Easy Rider tomorrow.

I'm not sure about coming up one that's "bolt-on" ,but, I'm using a walbro carb that I got from pocketbikesunlimited.com and it works great. I did have to drill the manifold provided out to fit the "stock" intake manifolds diameter and drill/tap one hole through the "stock" intake manifold to match a hole in the carborators manifold. It was pretty easy and it works grrreat.

It was called a 16.5MM remote purge carborator, was for any of the 2-stroke 48cc pocket bikes and I just chose the 48cc model, though all of them are for 48cc engines the intake manifolds differ a bit bike to bike.

good luck...
