Hi all,
gp150 in the last few weeks has started holding back, stuttering in all gears when at higher revs.
Ive changed carbs, fuel tap, spark plug and cdi unit, not sure where to go next.
All advice welcome please.

mine was doing same, a very learnèd gentleman found that my crank seal has gone. I assume that it is holding up at lower stresses but gives out under a bit of pressure
