Any special advise on what need to do before, during & after break-in this 'fast & furious' engine?
..for info,..I have 35plus21..just after finished break-in (after 10 tanks), eng. compression was completely lost due to inside bearing seized..but once replaced by new bearing, eng. runs perfectly ok till now....just to add on here, I had never experienced lost of compression (after broken-in) on my other .12 engines.
