    Big question is the carb. When are you fitting the 088 carb?

    rules state it has to have stock carb but can be modified. stock air filter and cover must be in place.

    Trying to learn something here, what attributes/running characteristics lead you to that conclusion?

    I tested the saw with a stock piston, timed cuts. I then swapped the piston with one with a 4deg duration bevel n the exhaust port. tested and timed cuts. saw was faster and stronger. this tells me to raise the exhaust 2 deg and test again. if I get a gain, then raise 2 deg more. repeat till either no gain or it starts going south. put stock piston in and it will be 4 deg shorter timing. doing this allows me to back up without starting over with a new cylinder.

    the other pistons are for the transfers. I was to cheap to buy a 4th piston for the intake, so I ended up grinding it to far. easy fix but loose time for testing.

    I think I worded my first question wrong. I understood what you were doing with the grinding on the piston so you could test timing without being permanent, but I was looking for what is it that you feel when your running it that makes you say I think this saw needs more or less of a certain part of the porting scheme?
