Answer 1

For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.

2 & 4 stroke engines can have similar problems requiring different repair procedures.

Check the compression.

2 stroke - check for leaking crank seal.

4 stroke - check for tight or leaking valves.

Answer 2

make sure throttle cable is not binding or routed wrong
