Powerhead

[Award]

well fellas I took powerhead pulled crank and pistons 1 piston was gouged and all the bottom rings were seized on one side of piston gonna have motor mic tomorrow cylinders looked ok but I’ll find out rear bearing was bad so I sure hope block is ok So is it worth it to rebuild ? At least I know it’s fresh

also it’s gonna be hard to see if it leaked water any where with out put back together

If bottom bearing was bad and allowed slop , the reed blocks need to be looked at as excessive play will wear the labyrinth seal machined into them.

Fatz what do reed blocks do ?

 

[racerone]

The reed blocks allow fresh air / fuel into the crankcase.-----Then the reeds close to keep it in there to be compressed.--------The reed blocks keep the crankcases separated.------Done with close fitting sealing grooves.-----Known as a labarinth seal.------Take the reed blocks off the crank to find those grooves.

only thing I can think of is water might have backed up through exhaust is this possible?
