I am struggling with a mis-fire at high revs, under load, when my engine is hot. I am still trying things one at a time to dignose the problem (ie is it fuel vapoisation or sparks).

So I have been reading this thread very carefully, and there is alot of information here, some of it hard to make out though.

My question, something that has occurred to me as I read...if the resistance in a ballast resistor increases with temperature, does the resistance in the primary windings of a coil not also increase with temperature? If so should this not also be factored in?

Cheers, Tom.
