    Motor has always ran really good but a little cold blooded and sometimes would die moving from neutral to forward idle.

    I am seeing a small puddle of clean gear lube leak out my prop. I had not run the motor for 2-3 months. Took her out and now seeing clean lub leakking out the bearing carrier.

    Fuel line bends

    Re: Fuel line bends Thanks. If the heat doesnt cause an issue with the rubber or inside (teflon?) coating this may work (see pic). I put a little 2 cycle on the allen wrench and slid the hose on it. I applied some heat and then cooled. This got most of the bend. I'm doing it one more time...
