Finished puting my carb back together this morning and it runs like a top! I found lots of neat suprises when I took the carb apart... The float had some porosity to it on one side and aparently was taking on fuel and sinking to the bottom of the bowl letting gas just hose past the needle and flood the carb. That was no big suprise.
The real fun was the stuff I found from whoever rebuilt it last. They must have been drunk! The spring on the accelerator pump was on the wrong side so it was doing the exact oposite of what it was suposed to and there were several little rubber gaskets installed in places they weren't suposed to be so they were gapping the top (bowl cover) part of the carb about 1/32nd off of the bottom half where the two surfaces are suposed to be sealed together with a gasket. Essentially the fuel could splash from the bown dirreclty into the top of the carb where it is not suposed to. I always had a ton of afterfire when I let off the gas and now I have none. I can only assume that the vaccuum when I let off was sucking gas through this crack and causing it to run rich most of the time.
Anyway it was pretty easy to rebuild overall. There were alot of peices but I made myself a map on a big slab of cardboard and layed them all out in numerical sequence. Mostly you just take everything apart and clean it and put in a few new balls, springs and other bits.
