Gang,
I'm trying to troubleshoot a couple of fuel metering problems. The first problem is idle-cutoff doesn't actually cutoff. Recently, I've needed to use the ignition to kill the engine. Also, if I advance the throttle rapidly (faster than about 3 seconds) the engine stumbles. It eventually recovers, but it's clearly an issue. I've done some searching through the forums and I've come across several threads where people had similar symptoms and a common suggestion is disconnecting the primer to make sure it isn't leaking.
I'm not sure how to safely do that. I have an electric priming system. The fuel comes out of the fuel line just before entering the carburetor and enters the primer solenoid. It goes out the other side of the solenoid and tees off to two cylinders. Can I just plug the line that feeds the solenoid or do I need to disconnect the priming ports at the cylinders as well?
