A fuel tank that is too full could contribue to this phenomenon.
It also sounds like the low needle is too rich.
If the response is a 1-2 second delay,
we're talking about a rich mixture overall.
Are you hearing a "bubbling" sound when you give throttle?
Please give more details (i.e. the conditions/situations where you're experiencing this)
Say, engine temp, engine performance at idle, 1/4 throttle, 1/2 throttle, full throttle,
engine feeback when you release the throttle etc)
Is the clutch properly installed and engaging at the right time?
Did you add/take off any head gaskets?
Is the spark plug you're using suitable for your engine?
For the time being,
consider leaning the low needle by 1/4 turn,
the same for high needle. =) |
