HELLO!!!

guys i need help. zpt

first sorry my bad english, google helped me with some words.

my new grubee 66cc in hi rpm runs like a charm BUT in low rpm it make that classic sound as if choking when i push the throttle: "buóóóóóó".....

the engine HAVE power and torque, but for ex:

to go out with her, she has the strength just to get out, but the engine does not turn up, I need VERY pedaling, and as it rises slowly turning when it comes close to the 4000 rpm, then it is replaced by force and that runs is a beauty.

I diagnose this as excess fuel. am I right?

to fix that I should adjust the needle or the float?

PS.: i´m using the 100% Sintetic Castrol TT, the engine is NEW, and i´m using 40ml/1L on the 1st fuel tank.

I'm using a lot of oil?

peace - Felipe
