Did some searching here on this topic. So i knew what i was getting into. My 80 110 allways had an issue with the carb. Either the engine would race or not want to idle, leak etc. Now i rebuilt an cleaned several times. So i order a ebay carb, around 40 bucks. What have i got to loose. Bolt up the new one. A few minor mounting issues. Crank up an runs and idles perfect. So here is the problem. MAJOR bogging other than ildle. So without getting into all tha little details this is how i got it to work. Used stock cap,main jet an needle jet in the ebay carb. Trial an error with the air mixture. Now it cranks, idles an runs better than it ever has. So. So far so good.
