I have a GV150 here. It's on a Vulcan (superswift) babybob.

I have a Superswift contractor base that i want to fit the motor too. I think they will be a good match.


I pulled the carb apart on the motor, cleaned it all out, emulsion tube was covered in crud.

I think i have the linkage all worked out. Perhaps too much pull on the spring as its revving a bit hard.

Just ondering what the specs were for the adjustment screw on the back of the carb. Is it a mixture screw?? Low speed or high speed.

I cant seem to get it to either idle right, or not hunt at revs.


Can anyone help??


Cheers, Bob. [Linked Image]
