Jim on a couple of my conversions after a glow break in I just put some diesel in the tank ( glow head and plug glowing) and they
ran, a couple ran ok, but died on transition, as one was about to quit put the glow back on and it picked up. I then switched to the diesel head and all was OK. my eyna 40 4 strk open rocker ran fine on diesel but down a bit on rpm martin
