I don't seem to have full power. Also I cannot lower the throttle to low speed it just dies. I have to stay in the throttle area from start to fast. Any input would be appreciated.....
check you have spark on both cylinders
Also do a drop test, (try seeing if its only one cylinder working by pulling each plug off the motor in turn, noting the difference, then replacing, sounds like its running on one cylinder
I agree it could be on one cylinder.
Also there is a low speed and high speed mixture adjust needle valves.
Initial setting on Idle valve needs too be one turn out from gently bottomed,
High speed initial setting is 3/4 turn out from gently bottomed.
You may have to remove the knobs to do the initial settings.
Once the motor is warmed these need to be adjusted at the appropriate speed.
