I already spoke to Bill Hughes, he knows how to rework them and I am ordering a rod from him. His main points are (1) replace the rod right away, they are the big weak point, and (2) get the compression up to spec, the head volume is too high stock. And the old low volume pipe like I have is not as good as the newer one. Oh well, it's good enough for an SWR.

With IMC there is no need for melt down. Kill it or richen it, whatever is needed. No need to suffer through 10 laps to get an official while the engine immolates itself.
The engines run pretty hot in ukie speed apps, they run a fine line on stinger exit area to retain heat for maximum power output. More than one speed engine guy has recommended opening up the stinger area a little bit to make it a bit less critical. This is likely another key point regards longer engine runs and overall longevity.
