Re: O/P gauge needle vibrating....
I just checked the console gauge. I connection has been leaking a little bit. I was able to tighten the nut just a little bit and wipe up the oil that I saw.
I started the engine after putting everything back together. I didn't rev the motor, just let it idle. The needle was steady @ about 35 with the motor semi-cold. I will drive it around the block. If it looks ok I'll head out to the show.
Must make note to cut line and install new farel @ back of gauge.
