The used to be a link to an excel (or other) valve shim calculator on the site and I had it saved but the old computer crashed.
Anyone have the valve shim calculator saved or a good link for a new one?
Thanks,
Chuck

Why do you need a calculator? You measure the existing clearance and if it's tight you go down a size. If it's loose you go up a size. Very unlikely that you'd need to change by two sizes. At least, I never have.
exercise in futility ?

I provided a link to one
maybe some folks are not as good at math

Perhaps a new valve or two was installed and I wanted to make it easy on myself....

OK but it's still simple maths. e.g.
If your clearance needs to be 0.2mm and you measure 0.9mm with 3.00 shim in there. 0.9 - 0.2 = 0.7 + 3.00 = a 3.70 shim needed.
If you don't have any clearance you can't calculate anyway so need to insert a much thinner shim first and then remeasure.

If you had my luck, you'd want to double and triple check every calculation.
This project is all because a spark plug came apart and bent two intake valves; see what I mean?
Bad Luck!
