"Dan and netters It would be very easy to wire a primer solenoid into the starter circuit for use only while starting."
Here are some additional thoughts after Brian's post between Dan and I: start of fuel flow. As a quick fix I would add a single primer injector just AFTER the carb, and only shoot fuel after the engine is spinning. If it fogs the mist then it will work just fine. With a split intake, installing the primer injector at each port is obviously the best spot for nearly direct injection. But, since you are not running the engine off this injector, but merely wanting fuel fumes to be there to prime the engine so that it will start, the injector would be easier to install, and work just as well at the runner junction prior to the split into to two runners. This makes it easier to plumb since there are only 2 injectors instead of 4, less to go wrong, and still close enough to get basically instant engine response. As Mark L. pointed out, you could also actually use it to run the engine if something clogged the carb. I would wire it up so that you select the primer before starting, and then it activates when pressing the starter button. In a separate location would be a separate switch that can activate the primer by itself, maybe near the master switch. By needing to use the separate primer activation switch, you make a hot start better, because it should not need priming, (hopefully). During cold starts you use it, and separate switch allows for emergency use, or if prime is not enough with engine spinning, if really cold out, say 30-40 degrees and you need a few seconds of prime by itself first. That would be my take on it, and the way I would begin to solve this issue... Colin Rainey brokerpilot9...@earthlink.net EarthLink Revolves Around You.
