Jim, I'm not sure if you have a primer installed yet or not, but it was my experience that without one, it won't start, no matter how warm it is. I don't know about the EFS-2, but the EFS-3 requires that on initial startup (first time ever) you need to suck on a little hole in the inlet (offset to the pilot's side) while the fuel pump is running, which will allow fuel to flow out the spraybar. That sets you up for first start. Use a piece of rubber or urethane tubing to do the sucking. I have one primer solenoid that splits in two, with one nozzle feeding each of the two intake runners on my engine. It works, but it's iffy sometimes when it's really cold. William Wynne set up a few where only one primer nozzle (make sure it's an official nozzle with the little orifice in it) goes into the main inlet between carb and runners, somewhere near the top before it splits. He says it works great. I plan to set mine up that way one of these days to see if that'll work for me. So to answer your question, go for it, and let me know how it works. If it doesn't work so well down low, you could always move it up higher. Mark Langford, Harvest, AL see homebuilt airplane at http://www.N56ML.com email to N56ML "at" hiwaay.net
