rbracer:

You could get a micrometer mechanism & connect this to a small vertical slide with a right angle bracket on the bottom, maybe with a small slot in the end to fit the valve stem groove.

You could bolt this to the engine somehow for stability & position the right angled arm on the valve stem & turn the micrometer mechanism to adjust valve lifts.

If you need a quick drawing send us an E-mail

Here is how I do it on my flathead engines.

Should be self explanitory on how it works. Probably a tight fit on a Briggs block, works well on the cast iron Kohlers I work with. I have to come up with a similar setup to work on the Briggs 12hp alum block flatheads for engine development work I am getting into in the near future for the USLMRA racing tractor series.

The one in the pic is from Harbor Freight on sale for $6.99. I had to cut the back lug off for my application. Simple, cheap and accurate enough for my application. I didn't care to destroy an expensive dial indicator for my setup. Hope that helps . . .
