For my glow engines, I tune the low end by pinching the fuel line (close to the carb) and listen for the engine to speed up. I keep tightening the needle valve a little at a time until the engine no longer speeds up when the fuel line is pinched. Then I open the needle back up just a little. Just wondering if this method works on gas engines too? |

NO!
Glow engine carbs are muffler pressure/gravity fed. Your carb is pump driven. You need to remove all GLOW FUEL methodology from your thinking. Especially regarding tuning...
