Im new to the hobby. A few months back I purchased a NOS K&B .61 glow engine. I hooked it up to a stand. Everything is hooked up correctly with my fuel tank. My adjusted fuel valve is 2.5-3 turns out from what was told is a good starting point.
I hooked up the charged stick to glow plug. The motor will run but for only 3-4 seconds then it dies. Sometimes it starts hard. I tried leaning it out & richening it with no changed. The carb it came with has one of those flat disc on the side you can adjust. I tried everything. The fuel I'm running is Cool Power 15% green fuel non castor. Someone told me I was nuts to run it on a K&B .61 others said it will be fine.
I have tried a different glow plug that's for this motor with no change. I am thinking my issue could be the wrong fuel or carb. I have taken the carb apart and cleaned it. Everything looks good. Im stumped. Any suggestions or pointing me in the right direction would be much appreciated.
