And another quick one I know then your take out the air screw there is a realy small rubber O ring that is the size of them and there is a flat metal O ring in there I only got one out . I had a buddy who cleaned them for me but Im not sure if he pull them all in? I can't see ? Any ideas ? And the same buddy said he cleaned them really good ( that's why I'm cleaning them now 2 weeks later) lol broke the in side screw hole in the bowl the one the acc. Pump is on . Like he screwed it on to hard ? And didn't tell me till I went to clean them and I seen gum like hard crap ( jb welded ) he tried to fix it .   Long story does anyone have a acc. pump bowl ?

The float bowel might be hard to find. I have seen complete sets of keyhole carbs on ebay, for $50.00. The little o-rings, and washers come in some carb rebuild kits. I know the one's Jerry"s cycle parts sells have them in the kit. http://jerryscyclesvintageparts.com/
