Status: offline 		Hi Guys, I have a 3W60 that's been lying around waiting for me to finish my YA Spit. Went to bench run it and it won't start (My arm is killing me LOL). I rebuilt the carb last year and made sure everything was in the right place. I also made sure it was pumping frm the tank to the carb and the carb was good and wet. It fired off the prime and then wouldn't start. Somewhere I read there is a safety feature in the ignition which BTW is an older 4.8 V. I also replaced the plug with a new one just to try to eliminate obvious things. Any help would be appreciated. The plane is ready so I would like to install the engine knowing it will start. Thanks in advance. Oh ya, there is a reed on 3W but I'm not sure if they go bad over time without being used.

If it fired off the prime you're getting a spark so you have a fuel draw problem or your needles are closed too far.

Status: offline 		I would have Gerhard send you a spare cap kit when he ships it back to you. You may find that it will be handy to have when you are off at a fly-in and it wont start again .
Been there - done that!!!
