Alright been rompin the haspin tractors to find weeknesses to fix them before my visit to haspin acres. Murray needs a bumper otherwise pully swapped. And my other tractor blew the headgasket and the piston rings are bad. I dont have an immidate motor replacement i might have a spare block but its untested if it isnt any good i think im gonna have to start building my other yardmachines it has a 14.5 briggs that has its fair share of problems but runs strong and pulls harder than the 16.5 on my murray. Would it be better to build the tractor i have no spare transmissions for, or swap engine blocks on the one i have spares for?

I’d say swap the rings and head gasket and go from there. Are you sure it’s the rings and head gasket? A bad head gasket will kill compression but you shouldn’t get blow by into the crank case.

Where those briggs OHV engines like to blow the gasket, you WILL get blow by. They blow right between the cylinder and the pushrods. Combustion goes right into the pushrod/lifter area and into the crankcase

I’ve got a couple spare engines. Including an oppy. Untested, but they aren’t hard to get running. I might see if I can get it running in case the need arises. Also a 14.5 OHV. Maybe a Flathead too but I can’t remember

The crosshatching and the bore look absolutely brand new, the engine burned oil like a freight train and fouled the plug all the time and it progressivly got worse im gonna rebuild the head and i ordered a new headgasket im gonna lap the valves while everythings apart unless they seat pefectly.

I dont know what kind of money i will have but if you have a 14hp flathead i might have to find a way to releave you of it. That is one of the easiest motors ive ever worked on i had one on my first racing tractor

Ive got one tractor down the "rocket" yardmachines blew the headgasket and now one tire blew out i dont know if that mower will make it so i might have to take the murray and the other yard machines instead of rocket which today i worked on the "other" yardmachines and it runs 1000% better than rocket it putts with the throttle all the way down and runs really really well i am liking that mower having the "manual" vari drive thats selectable instead of the plastic junk

Head gasket fixed and my backup mower turned out nicer than the main mower i might just rob some parts and bring the backup mower its really nice, i also managed to score a huskee that has a kawasaki flathead swap.
