Reading through the Instruction Manual for my ignition unit, I realised one of the sexy things it can do is retard the timing 20 degrees on start- up. Last year I was experiencing some real difficulty getting the engine to fire once it was hot. After screening the fuel lines, wrapping the headers and putting a new (bigger) battery in the car, the situation seems to have improved, but would retarding the timing on start help further, or is that overkill?

My opinion is it only helps if you have a lot of advance and a lot of compression. You don't have that much of either Tim so I don't think it will work. Retard it 20 degrees and it will not fire at all in fact!

Thanks Dave, taht's pretty much what I anticipated, but thought it was worth exploring.

It seemed to start without too much fuss at both ends of a trip up the road to the local gas station, so fingers crossed it's sorted anyway.
