72 35hp chrysler timing

[sprithunter]

Had problem with my motor running last year. Changed plugs, points, condensers but it seemed like timing was a little out of adjustment. How do you time this motor out? I read the manual but it does not specify WOT or at idle. Any ideas would help. Thanks

If it specfies something like 22 degrees, then that would be your WOT setting. Best to do this with a test prop or carefully on the water, with someone driving while you shoot the light at it. Please be careful if you decide to do it on the water!!

According to the Seloc manual , if your engine is magneto ignition, the timing should be set at 28 deg WOT. You aren't going to have much luck finding the Chrysler timing tool . I'm using a 360 deg protractor to mark the flywheel and then go from there. Also , if your engine is battery ignition , the timing would be 32 deg.

Thanks for the info guys. I will most likely be timing the boat out of the water. WOT doing timing doesn't seem like this would good idea. I don't remember which manual I have because copied it for a libary book about 3 yrs ago. Boat restoration took all my money. So again thanks. Happy St. Paddy's Day

By the way Scotiany where do you put the zero mark on the flywheel to get the proper degree mark for timing?

Well, I'm going to find TDC by sticking my caliper in #1 Cyl and rotating to its highest point. You could do the same thing with a screwdriver. That is the position where #1 cyl points should just begin to open. You could wire up a multimeter or light to see when that happens. If your coils are under the flywheel, you probably have a magneto ignition. You could also use a sewing tape to figure out where 28 BTDC is but, I think that 's complicated. The Seloc manual has a really understandable procedure. You should get one-it's worth it.

Thanks Scotiany will try it out soon.
