Thanks guy's, looks like a few different ways to try.
I'm squirting gas down the stacks now but might try other methods.
How much timing does alky like, mine's 36 at the moment, if i bump it up to 38 it seems to fire better.
Did some searching on this and read one that said some engines with lumpy pistons need more timing than others, he was up in the high 40's.
Would this be right to get spark across the lump sooner.
