I have a 42 Allis B that when cold starts on the second or third pull of the crank. When hot however it may not start for 20 turns and at that point I give up and pull it. When we do pull it, it pops right off in a couple feet but all the hand cranking just doesn't do it. Coil has been replaced in the mag as have the points rotor and so on. I have pretty much done everything I can think of to correct this. However all the work I have done still requires that small pull to get it to fire up. Once the temp comes down to a much lower temp this will start like this every time. I just can't understand what the issue is.
