I have just opened my second 132 cub transsexual version engine which has stopped working with only one cylinder because of a broken valve spring cup, I was planning to take the opportunity to completely overhaul the entire engine but I am going from surprise to surprise I notice on the front cylinder head the exhaust valve is pressed into the valve seat, the new engine has covered less than 10,000 km I hope not to encounter any more unpleasant surprises when I finish dismantling the engine.

So for now a twisted intake valve on the rear cylinder and an exhaust valve on the front cylinder, the cracks on the cylinder heads don't worry me I continue to disassemble.
