Think I might have a coil issue, but here is what is happening. After saw warms up for a minute or two, I have worked on tuning the carb using a tach. After 4-5 minutes, the saw just acts like it is running out of fuel. So far, I have tried two different new carbs, installed new impulse line, checked the fuel hoses for cracks, checked the fuel filter, intake boot and made sure the tank vent is clear. Also checked the coil to flywheel gap and spark plug. Any suggestions on what I seem to be missing?

OEM carbs I hope? Sounds like the coil. Make sure the tank vent is working, or remove it and try once more before you buy a coil.
Aftermarket carbs. OEM tank vent that has clear flow when applying vacuum, but stops when blowing. Simple test with slight pressure and vacuum using my mouth. Will give it a try tomorrow with the tank vent removed.
How do the aftermarket tank vents compare to the OEM tank vents?

Tank vents either work or don't . Since it runs OK then craps out in 5 minutes, I say coil prob! Get an OEM coil. Look for spark when it dies in 5 minutes.
