Hi Paul

I do remember that one fo the engines was "odd"..... we did strip it of all usable parts as we usually do for all old blocks ...... had a strange intake that was cracked...... will ask my mobile memory...Grant.... tomorrow if he remembers more than me..... I do not remember taking off a governor....although I have collected a few NOS that will fit the small bolt pattern of the 235 carb.....but would not fit on my 261....

From what I have read pre-ignition or pinging is the culprit and not over-revving and such a situation is encountered when lugging over long hill.......

Over time I have given up mon using a strobe light on a cab 11 engine.... I have transferred the TDC markings from the flywheel to a marked on the bottom of the flywheel with the sheet metal cover removed and also on the top under the small plate bolted on top of the bell housing....... then I go by feel and trial run until I find the sweet spot...... I can drive my C15a in fourth gear going around a normal right or left turn....at 12 to 15 mph on flat ground and pull it up with slow throttle to it's cruising 35 mph with no ping or stumble........ vacuum shows about 4 to 5 inches vacuum to its steady 20 inches to flat out 40 mph...... another 4 to 5 mph if I let it get its wind!!!!! and the road is flat and long enough....

It is impossible to get a a strobe light to fit into the engine compartment ever since all the sheet metal has been installed...... got the tip from Phil W. and went further by marking the flywheel on both spots with center punch and white and yellow paint..... using a hand crank made the job more accurate.

But to have two engines melt a piston top is both cruel and weird!!!!!

I have seen a over revved a 251 dodge 6 (M37) with a big hole in the side of the block driven 20 miles back to the garage..... albeit at slow speed.......

The good old days!!!!!
