Vespa parmakit timing

Does anyone know which marks to set the timing to and also what rpm to check it at?

I have a p200 with a 60mm crank spacer under the barrel with a malossi kit, reedvalve etc

If i put it on the 125 or 200 marks it runs really rough low down but if i set it so its 1mm before tdc its fine but wont that mean that its to far advanced when the revs rise?

Any advice would be very welcome as i dont really want to hole a piston or anything.

Hi John

 

If i understood right you got also a tuning cylinder like malossi or polini on your engine ?

I recommend you 23 degrees with 2000 rpm. Please use the flashlifght to be shure !
