OST-053: Massaging a 20V Blacktop

[oldeskewltoy]

20V shim tolerances are pretty bad. I've now had new, as well as old shims, and in some cases the shims vary by as much as .001" (up to as much as +, or - .0005" either way). I have purchased shims now from a supplier here in the USA, as well as directly from Japan.




with that kind of error, and a still small, growing - but still small shim bank, to set tolerances to within .001" was going to be a challenge... but I did manage to set all the intake with nothing tighter than .010", and nothing as loose as .011", and setting the exhaust side with nothing tighter than .017", and nothing as loose as .018"......

I'll wait.....


I did need a bit of "help" to do it......
