I want to check it on a kubota engine that uses shims under the pump. The crank has "FI" marks for fuel injection BUT does this indicate when the fuel should start to flow or should it be the end of the injection squirt. My manual says to use the inside of a pen so you can see the fuel move but it didn't say that it should start when the pointer hits the FI mark or it should have finished. I'm wondering if this is why an engine i have smokes a bit at startup, by a bit i mean a cloud if i didn't give it a really good glow. It may be squirting too early when the air isn't hot enough for ignition, and yes the compression is quite good, 375-400 PSI i think it was.</p></blockquote><p></p>
