I was on the Dragon and looked down. The tach was twitching between 0 and 500-back and forth. I have a new cable last year and it was tightly screwed in to the head and cam cover. I took the head apart and the needle is attached to the shaft. I hooked it up to my electric drill and it showed rpm. Any suggestions as to where to look next would be greatly appreciated. Also, as I put it back together, I was considering adding a lube to the gears one the rear of the unit. I don't know wether to use oil or grease but I'm thinking grease. This is not the pot under the needle. Thanks for any help.
Ps. I'd add a picture but I know my limitations.
