Chris -

>Would it just be easier to limit the mechanical advance so idle would stay the same? I figure some modification to the weights would work.<

If you make the weights lighter (grind metal off) full advance will occur later - ie. at a higher RPM. Or you can install stiffer springs and get the same result.

Tip: When messing with timing don't adjust the distributor more than a couple deg before TDC at rest. Otherwise the engine will want to backfire when cranking, making it difficult (or impossible...) to start.

>Is there some way to check timing with a light as on a car. I see a timing pointer, but not much on the pulley in way of degree marks. <

Sure! A regular automotive timing light works fine. There's a notch in the crankshaft pulley for top dead center. (Or if there's two notches close together TDC is the first notch to pass the pointer in the direction of pulley rotation).

A second notch a couple inches away marks full advance - 35 deg I think.

You can figure and mark intermediate timing settings between the TDC and 35 deg notches, then use a timing light to set timing.
