good used Mcculloch MC90 kart engine with new .005" oversized piston and rings, no casting issues with threads or fins, All OEM as sold in the mid 60's. Fresh hone to fit piston skirt diameter in a machine shop using a precision sunnen hone machine. Includes the 5 degree advanced timing flywheel.
Will need spark plug (7/16" reach L78 or NGK BH7S), crank seals and possibly a condenser after so long, same for the 2 diaphragms for the carburetor. Carburetor throttle return spring 48820 will also need replacing. All hardware included. production for this model was for only 6 months in 1968 I believe, combined with all good parts as well as a fresh bore, I am asking a fair price.
Crank bearings are fine, but some like to replace them while its down. Just don't use third world bearing from places like India, China or Pakistan.
Send name, phone number and location to get a reply please. If your foolish enough to ask "is this still available" I will delete your email.
$575.00 cash firm price
I took some extra time to make sure all the necessary hardware was included.
Some buy wrecks that are assembled, you can't see the crap they're trying to hide inside.....I do things differently!
