I DO NOT want to spend days in the pits fighting to get the thing started and tuned. I was flying two weekends ago and a guy came to the field with a new gasser and spent the better part of 3 hours just trying to get the thing started. I left after 4hrs and he still wasn't up in the air. This is what I want to avoid.
One thing to make sure of before trying to start a gasoline engine is to get the fuel to the carb. Irun mine dry, so it takes some "pumping" to get the fuel from the tank to the carb. You can either "rock" the prop or spin it - with the ignition "off" of course. My Fuji 34 (magneto) is amazing in that it has always coldstarted with the following procedure: Close choke. Flip <u>backwards</u> until the first "pop". Open choke. Flip six times. Always catches on the sixth flip.
The Fuji manual gave that clockwise (backwards) until it pops suggestion and Ihad never tried that before (we used to start the Cox 0.049 glow engines by flipping backwards).
Once it has run and is still warm -one or two clockwise flips and it's running again. No heater/glow driver and no starter motor and battery needed. Just a leather glove and a can of gas with a pump. Nice and simple.
And that sound of a gas engine idling after you flip start it. It's just the best sound there is (IMHO). Not the screech of a glow engine; but a great "put-a-put-a-put-a" that sounds airplaneish.
Ithink Ihave adjusted the carb jets once this year since the start of flying season. Probably will have to richen up a bit since it's getting colder now. No more futzing than some 2-cycle or 4-cycle glows. Much less than the last Super Tigre Iowned (very sensitive to adjustments).
My little G-26 Zenoah (also magneto) has days that the first start is a bit "crankier". But even so If it hasn't started by the 12th flip Istart checking for fuel feed issues. Thereafter, one or two flips gets it running after refueling. My Fuji 43EI - two or three flips even cold after that choke-on "pop".
