Amici,
Got the motor running last night. All the problems that I have been having;
slow cranking, fire in the distributor, intermittent spark; were all due
to...... engine was not earthed! Yup, stoopid me forgot to ground the
engine.
I was hooking up some safety wire to run the 3 chokes when the wire started
to glow red when it touched the body. So I hooked up a grounding strap, and
the motor fired and ran within a 1/2 a revolution. 100 lbs of oil pressure,
perhaps a little high and I should check the oil pressure release valve.
Motor sounds awesome. Ran it at around 2000 rpm. Plugged a few leaks while
it ran. The GP3 is a nice sounding cam. Played with timing. I set the
roller rockers per the instructions (17 thous on inlet, 19 thous on
exhaust), but they sound a little noisy to me. The head is getting a lot of
oil.
I'm going to have to strip the carbs. I pulled the plugs and 2 of the plugs
(Champion RNY7C) were wet (not from the same carb, so not a float bowl
problem?), and the other 4 were very sooty. Curiously, the header from one
of the wet plugs was hotter than the others. Thats bizarre because I
thought that the hot header would have been due to a lean condition. I
think a carb teardown is in order.
I'm going to run stock plugs (Champion NY9) as well, just in case the cold
plugs that I was using were not correct.
Woohoo! I'm a little deaf now as the motor was unmuffled. It certainly
sounds strong and studly.
Shane Ingate, stoked in Maryland
