Hi everybody First post and i hope i'm in the right area of the forums. I just purchased a 70cc engine and am loving it. Call it pushing 40 and loving the assitance. Love the fact of being able to get back on a bike, But this time when i get tired I just "pop the clutch" and enjoy the scenery! My question is, I have to run the engine with the choke 1/2 to 3/4 on all the time. At this choke setting the engine runs very smooth. I must be missing something for it to need the extra fuel. I checked all gaskets for leaks and cleaned the carb. The float arms are sitting parallel. Any help would be great. Also any tips on vibration ?? I still can't feel A#$ !!! Thank You !!!
