Yes this is the crankcase and cylinder only, everything else is swapped over to the new crankcase+engine now. Just the bare crankcase and cylinder only is where I'm noticing this; much different than the brand new case! Now that I have a known good engine/case assembly I can tell for sure...

Something really is up with this bottom/top end... When rolling it over top dead center it moves like it's spring loaded at the top... Turning it to the top dead center is almost like holding magnets of the same poles together it just doesn't want to do it... Going back and forth at top dead...

😂 that's frank-an-sure. And a new clone crankcase with a 52mm engine on the way.. to add to it

Oh right on, definitely worth it for that price!

Oh the Jonsonred is red, I see, ya the rear half with the fuel tank and handle is all red painted over with orange, also the crankcase is painted over too! It has a flat top cover for the air filter. The cylinder cover plastic is original orange along with the intake cover. All I know is the...

The original cylinder is in pretty good shape, put it on with new rings to keep the new one as a backup but...

Or maybe that's just corrosion from carbon steel to aluminum contact idk

It looks like someone went at it too aggressively with oxyacetylene 😂? just a guess. I'd like to sandblast the cases and refinish with epoxy primer but don't know if I will. Prev owner sprayed over most all the exterior with a brighter orange. Aside from this the case is in pretty good shape

Gonna put it on the backburner for now. Hoping to figure it out eventually but for now tired of screwing with it and going to swap out the lower unit with brand new clone to do some cutting. That should help diagnose too

Hnsavrqua 😂 that's impressive for sure. For the price on a new unit it's no doubt something I want to try. As for the kill switch mine doesn't always work but the choke works just as well, and was going to unhook it altogether but not sure if that would cause an open circuit.

It's getting ridiculous enough I might just buy a Holzforma lower unit, probably should've done that instead of spending the $100+ on parts. Brand new lower units for 105+ tax I'm sure they have machine pressed bearings in a clean factory. The farmertec cylinder and piston meets my quality...

Ya for some reason I hopped on youtube right after posting this thread to research the 372xp bottom end. The replies are more and quicker than expected for sure. Thanks to everyone for all the replies!

I guess first I could try to pop out the crank seal on the one side and replace while making it flush with the bottom of the taper.. this one might've got tapped to far in, it's further than before. The paint line is to the bottom of the taper and this one is nearly 1/8" past that line possibly...

I do know for sure that the old bearings had no wobble play at all and no side load wobble whatsoever so it doesn't make any sense how the crank would be tweaked/bent at all without leaving the bearings in worn condition.. however it never ran once after this happened only pulled over several...
