Just a question for you all, I'm trying to get my Poulan 25cc conversion running well on glow. I have tried an OS type F plug (the 4 stroke one) as I beleive its a hot plug. With straight petrol/oil mix it did not run really well even with the glow powered all the time, and trying 25% methanol, 70% petrol, 5% oil made pretty much no difference. Ideally I was to run straight petrol as there is no mixing to fart about with and its easily available, where as Methanol is more difficult over here.

So I'm thinking if I should be using a different plug but a search back through the tread does not really mention plugs for larger petrol engines. Is the type F the best plug, or should I be using a #8, A3, something with an idle bar etc etc? To loose the onboard glow would be even better so any suggestions or info from your tests appreciated.

Cheers,
Rich
