All engines have some "klank" in them when turning them back and forth. If
you had a bad rod, you would not be turnning over the engine.
I'll look inside the engine soo, through the intake port as Chuck suggested.
If piston to head clearance was a problem, the plug ground eletrode would
not be welded, but bent or smashed into the center electrode. If it is
indeed welded, then it got to hot. It can't get to hot without the piston
getting too hot, i.e. melted.
I've seen too hot, where lectrode and ground are melted, and I've seen the
most recent where they look to be welded together at the tips but with no
rela indication of disfiguration due to lack of clearance.
The jet size sounds right. Do you have the primer ports on the carbs
covered, or if you are using a primer, make sure you don't have leaky
hoses
or primer pump.
I've got the old kawi style primers I'm told. A cable affair that reach
downintot he carb area.
I will most definitely move the CD and coil into the air stream. Good idea.
Is your engine hard starting and will not seem to idle smoothly ?
The car has never been hard to start and it runs quite nicley at idle. It
isn't till the car has been run with enthusiasm for 10 min or so that it
starts running raggedy and finally stops running on the left cylinder. That
ultimately brings the other side down.
