…having a bit of a recurrent problem on my p200
On long pinned back throttle journeys I am getting bits of crap stuck in the spark plug which is stopping it sparking properly, making it lurch about and not run properly.
Anyone any ideas what could be causin it?
Cheers

When I drove moped, back in 1959-1960 this happened to me, as well as my friends, every now and then. As it is not common today, I thought it was the quality of the petrol and oil that caused it. Are you engine running to rich?

Bits of carbon maybe? Perhaps decokeing the topend may help.
Have you tried with another plug?
Does the plug have the right heat value, gap distanse?

Plug is a good colour so I don’t think it is rich, although I probably run it a bit flat [mark=red](not revving it high enough)[/mark]most of the time, don’t know if that’s causing it.
Use the same semi-synth oil as a mate in his p2 and he has no problems, might start putting the same fully synth in as I use in the smallframe though.

Back when some cars were 2-stroke, I heard many times that to clean out the engine one should take it out on the freeway, and drive it with the trottle wide open.

have you got a CRUST around the electrode??? if so toooo much oil
I am going to have a look at the cylinder head.
