Have really enjoyed riding my naked PRR around in the sunshine, although when I set the timing with a strobe 1-4 were perfect but 2-3 bounced all over the place. Points and condenser are both quite new. Not sure what else could cause it, although 2-3 coil is a new aftermarket one which is a little smaller than the original, could this be the problem?
It pops when cold, usually on tickover or deceleration, I put that down to my unbaffled motad 4-1, I have overwelded any holes in the pipes though and when I use my hand or wire will as a temp baffle it still pops.
Shall I try new points/condenser? Is the coil the culprit - how do I tell?
