The feeler guages you're supposed to use are: .15mm and .30mm.
Gene,
0.19 mm intake and 0.32 mm was just an example of what might be the actual spacings vs. the measured ones.
I did use 0.15 and 0.3 mm, but that's only the lower end.
The feelers were sliding easily, which means that the spacing is actually greater than the feelers' thickness. But, by how much ?
For that I used the next feelers in the set to make sure that 0.2mm and 0.33mm did not fit. So, the actual spacing
for the itake is greater than 0.15 mm and less than 0.2mm,
and the spacing for the exhaust is greater than 0.3 and less than 0.33

I guess if I had 0.15mm and 0.16mm that improve the precision.

Pop,
Take a look at the OVAD, it tells you about "feeling out" the amount of tension you should have as you drag the feeler gauge across. You definately need some resistance there.

good luck,
