Mine hasn't done this yet. What's the cause? Fuel stop in the carb not set right?

This is why we asked Brad to help moderate. He has all the good ideas.

I only have issues with leaking B&C oil, and not on all 5 of mine.
I store all my saws with full fuel tanks.

Okay, Gotcha. That why on builds guys say they polish the needle seat.

Basically it's a quality control problem.

Its also a good idea to try to polish the seat if you have to drill the orifice out to increase fuel flow.

I've always noticed on my two Makita's that they build a lot more pressure in the fuel tank with temperature changes compared to the other brands. I started to get into the habit of cracking the gas cap before I begin to start them. If I don't, they seem to flood immediately.

I've had problems with them flooding when I run one right after it's been shipped to me, other than that it hasn't been a problem for me, seemed odd.

How'd you find it, pulling it apart to port it.
Was it shipped with that in there, sure the oost office would like that . Then again, can't tell you how many guys have sent saws full of fluids .

Most of them I’ve picked up at gtg’s or they brought them to mine.

Yours didn't have any crankcase gas in it by the time it got to me. Reckon @markds2 stole it?
