7.5 sears ted williams timing

[dunk1]

I have a 1972 sears ted williams and was wandering if the timing could be adjusted. The motor runs o.k. but it just seems like the timing is off a little. Any help would be great. Thanks

Re: 7.5 sears ted williams timing

Compared to other motors you're right, they do run a little off. And they always have...at least in my experience. As far as adjusting the timing, I will assume that you are talking base timing since a lot of the rpm increase is the result of advancing the timing. The butterfly in the carburetor doesn't open till about half throttle with full open happening just after maximum timing advance.

Opening the butterfly without advancing the timing only results in bogging the engine. If the butterfly doesn't open fully at maximum timing advance then the motor will not reach full rpm under a load.

The term "timing" when used with outboard motors refers to the relationship between the ignition timing and the carburetor.

Now having said all that, check the timing and adjust accordingly, it may run better than OK but I'm not holding my breath.
