I'm doing the shims on the Divvy.

Number 4 shim has a gap smaller than 0.002 thou on the inlet. (My smallest feeler gauge)

I'm assuming this means there's no gap and it's therefore *smaller* than 0. (Always pressing on the valve)

Since the chart doesn't cover values smaller than 0 how can I work out the correct shim?

Have I got to instal the correct shim for 0 and measure again?

Difficult without seeing your table but how about trying one of these.....

Assuming gap is zero.
Fitted shim is .020
lookup up in table for gap of .005 and existing shim of .015

Or work out what gap + shim is supposed to be (say .030)
if gap is supposed to be .005 then new shim should be .025

It's assuming the gap as zero that gives me the problem.

I don't know that it *is* 0. It might effectively be -5 if the valve is being slightly held open.

However I will assume a gap of zero and see what happens.

Thanks for the reply!
