Check and make sure that your timing has about 34*-36* of advance at about 2200- 2500 rpm.

Get that f*kin choke wire off your coil.

LOL.

BTW: Real men don't use chokes. Double lol.

Choke? We don't need no stinking choke!

This is the same out drive and prop from the boat when it did run, right?

Heh, don't forget many people have run into tach's causing symptoms like this. #1 make sure it's hooked to the negative side of coil. #2, if it is, try unhooking tach and see if it clears out. #3, make sure ground from distributor is on and clean, ground from module, etc,etc,etc.

OK, went through the wiring - what a cluster! One thing I did was put wires back in that had the correct color codes so it is obvious what goes where. Had one green wire and one yellow going to the coil, which were supposed to be grey and purple but got spliced out at some point in the past. Then made sure coil was wired properly, and moved choke lead over to the relay for the fuel pump. Ran like a champ after that! Heading to the lake in the morning, and life is good again. Thanks to the guys at OSO! I owe you a beer if we ever cross paths.

If you are still on the trailer, how do you know everything's fine ?
