i have a 135 cc Yamaha 2 stroke. A few moths ago, i had it bored and had the piston replaced.
naturally the mechanic tuned the carb to inject a lot of fuel into the cylinder, for the first few hundred kms. during which it drank a sh*t load of fuel!
I visited the mechanic again to de-tune the carb, but i'm not happy with the work, especially because it still drinking an unacceptably large amount of fuel, so much so that the exhaust fumes are very, very thick.
also, at the point where the exhaust pipe meets the exhaust outlet of the cylinder, quite a bit of unburnt fuel collects, and drips slowly.
i just want to know, how should i adjust the 2 screws on the carb so that the mixture injected inside is a slightly less rich, and i get a little bit more per liter.
