An air cooled VW engine is another one of those "mechanic's nightmares" to rebuild. I drove a 63 beetle 1200 CC with a "big Bore" cylinder kit from J.C. Whitney back in the dark ages. It finally wore out the piston rings, and Whitney wanted to sell me a complete new kit- - - -cylinders, pistons, and all. I ended up rebuilding it with 85 HP flathead Ford rings and replaced the worn out piston pins with ones for a Corvair because stock wrist pins were too short for the oversize pistons.
