Carb Overhaul Findings

[Bob_Roller]

Got the last of my parts for my carbs yesterday, so I'll finish up the last few items. Found some interesting problems , first the needles on the slides, the left cylinder was set at position 2 and the right carb was set at position 3. Bing manual calls out for position 3. This was the first time the needles had been removed. Second the left carbfloat adjustment was way off, I installed the alcohol resistant float kit about 9 years ago, and I know I set it at the proper setting, as I made a tool to check the setting. This upgrade has two independent floats in each bowl, one float was correct, and one was 5 mm off. So if you have this upgrade, might want to check the adjustment on occasion, as it looks like you  can cause a problem by not being a bit careful re-installing the bowl. The throttle shaft o-rings were just dried up shriveled pieces of 'plastic' looking material. Everything in general needed a real good cleaning. Removing and re-peening the throttle plate screws are not that difficult of a job, so don't be too intimidated by it.

Exactly!! I don't know why so many otherwise knowlegable people warn others off it. Several carbs I've pulled have had the O rings just crumble, certainly not a good seal for the shaft, and very likely to cause tuning problems.

Instead of beating on the screws with a punch and hammer, I used an automatic centerpunch. 20 or 30 applications or clicks of the automatic centerpunch, and the screws are peened or deformed,to the point that they are not coming out.

when i rebuilt mine i have a couple of those pins missing so i just went ahead and replaced the gaskets underneath and used the same size bolt like on the choke circuit or shouldnt i do that?
