I can't remember if I have come across a Powertorque coil that was faulty, don't think I have. The occasional module can fail but not often, full crank modules fail and I think that is partly caused by the fact the module is mounted on the underside of the ignition plate and does not get any airflow over it. When I replace these I fit them on the upper side of the plate so the fan helps cool it.
MF I have had a full crank with a spark plug in the decomp hole and I struggled to find where compression was but it started easily and ran fine, and I used it for years like that.
Tyler, compression is good and there is no indication of any puff of smoke or hiss indicating the gasket being a problem.
AVB the jury is still out regarding how much compression is needed for these to run, this motor was running very well a few weeks ago. The lack of a kick from it with starter fluid above the piston still has me confused but it is something that happens occasionally.
I have at least 50 of these motors here that I am going to set up and test when my son comes over from NZ in a few weeks. That way we can use a known coil, module and carby. It will be interesting to see what the results are, at least then I know what can go to the scrap
