according to my manual.........

I want to link & sync my new old johnson 1990 120. The manual calls for a special tool to be threaded into the spark plug hole for tdc. Is there an online source for this tool or is there something else I can use? Thanks

Hi, Alden.<br /><br />I always found TDC by sticking a bit of stiff wire through the spark plug hole and noting when it "topped out" as I gently turned the flywheel. There will be a bit of a flat peak when that happens, so mark the center of that as TDC.<br /><br />Good luck.

I don't like sticking metal things in spark plug holes. Try a piece of 1/4" wood dowel instead. Turn the flywheel slowly and watch for the high point on the dowel. Once you find it, and are sure, you can mark the dowel with a sharpie or other waterproof marker at the spark plug opening. That way, you'll have a mark you can see at TDC.<br /><br />I used to do this with motorcycle engines, and had a different marked dowel to match each engine. It saved me a lot of time over the years.

Thanks for the advice guys. I will make you both proud by using hardwood. Stiff like metal but soft like wood.

Alden, remember to only turn the flywheel clockwise as per the manual!!
