Latest update from the front.
Of the 4 motors I set up with the reamed seats, 2 are now working fine as I have been starting them once a day and they fire straight up. The third one is a PT on a 24 and it starts but takes several pulls. This 24 is one I filled the pulley with lead and I'm thinking the starting problem is most likely the lead is not quite enough spinning mass to allow the motor to kick over. It still has a minimal kickback on the odd occasion so I will work on adding some extra weight.The 4th motor, sometimes fuel pours out of the primer bulb so this one I believe is a needle problem. One interesting thing is that on these 4 test motors I have used needles that I have previously rejected as faulty so now I believe the needles were not the cause of all the problems, it was the seats in the new primer caps all along. I will go through all the reject needles I have and test them all but I believe they are only a minor part of the problem. The saga rolls on
