Jimbob I actually have the pointslayer ignition from them on the motor. When I got the motor back from the engine builder a couple years ago and I finally got it in the tractor he had put the Chevy points on and they were a PITA so I bought the kohler points and they were not much better. I had a heckuva time. That led me to get the pointslayer. I love it, works great. Only problem I've had is the adjustment screw backs out ever so slightly sometimes.
I tore into it today after work once I was calmed down and not seeing red. Guess what, it's not the timing. I blew a head gasket. Again! I blew one last year and I've had barely 4 hours on the motor since the last one. Obvious question "did you check the torque after running the motor the first time?" Yes I did. I also checked the torque before I pulled the head today and they were all right on. So looks like I'm shopping for a new head. This head really can't be shaved any more, it's already been done once and he took quite a bit off to get it flat again.
Why do I love this machine again?
