Just completed the rebuild of our 300EX with a new (used) bottom end, cylinder hone and new rings...this is a Pro-X stock compression piston, cylinder is bored .020 over
She won't start, turns over strong but won't fire...good spark, maybe too much fuel...but anyways...
The manual says to test the compression, take the plug out and ground it to the head, then put your finger over the plug hole and crank it, and it should blow your finger off...ours seems to actually suck your finger in!
what is the cause of this?
timing (though i've checked this 3 times!)?
