Hey, I'm wondering if anybody could help me with hopefully a pretty basic issue. I recently acquired a 66cc 2 stroke. The previous owner complained about fuel leaking out of the carb. After watching a tutorial I figured out that this was a stuck float. I dismantled the carburettor, and in the process: removed the throttle assembly. I adjusted the float height to 21 mm. The motor now no longer leaks gas. On the other hand the motor runs far to rich, needs full open choke and full throttle to start and barely revs to a third of its usual rpm. I thought this was a throttle issue but after taking it apart and reinserting it a few times it still runs like crap. I think it is not the throttle and is carb related. I also cleaned out the carb while it was dismantled. Has anybody else had this issue?
 
Well, everyone one has suggested the usual suspects on your too rich issue.
How about way to much oil in your fuel mix? Are you accurately mixing your fuel?
I like to use a two liter pop bottle of gas with 60 ml of oil for a mix of 33:1 Some go heavier or lighter but it is important to be accurate.

It's around 25:1, ran fine until I messed with the carb. I'll see what I can do about gas tank venting, then If that doesn't work I guess I'll have to see if I can put the float back where it originally was.
