Made some time (while the wife is vacationing in New Mexico) to work with the K341 some more.
Had to get the cam and govenor out but the camshaft pin just didn't want to budge. Most of my punches would just bounce off. The punches just seemed to small, so I spun a piece of 5/8" round stock to .480 for about 3 inches (just enough to slide through the camshaft pin bore ) and with a large ball pein hammer - had it loose in 2 swings!
So I got the cam out, with the shaft and spacers and then the govenor followed.
I'll start cleanup of the block and then measure the bore and piston to determine wear next. Maybe I'll remember to bring the camera along so I can share some pics.
