newly installed ma12 engine

i really like my ma12 engine, more torquey than my ma10, especially up hills i dont need to shift to 4th gear anymore.... just push the throttle a bit more on 5th =)....and if i floor it in 5th gear the speedometer moves!!!...hehe...


but there is one small problem
on lower than 1/8 throttle it doesent run smooth...i get some exhaut puffs???
and when i push the throttle a little bit more it runs perfect again


(my english isnt perfect but i hope u understand what i mean...=))
