Thanks bob, that is good story to hear, I’m sourcing a better used piston for my own warm and fuzzy feelings anyway. I am definitely more sure on using the loctite 515 with SF7471 “primer type T”. The fact of it being a stout engine is why it is chosen over many other options in the 15-30 range. Not to mention parts availability and ease of maintenance/rebuild. One of those mercs might look better, but these darn things run even with significant problems present as proven above.

Again thanks to all who are participating in this discussion, it is appreciated, and good to see
