I'm New Here
I have a RV-7A equipped with the TMX-O-360, a MA4-5 carb and Slick mags with impulse coupling on the left one. When it gets down to 40-50 degrees, I have considerable difficulty getting the engine to start. I have tried leaving the primer pump on for 5 seconds and also 8-10 seconds. With about 10 seconds, it will cough, sputter and then die. When I do get it running, even up to regular idle speed, it dies about 3-4 seconds later. It seems to be running just on prime and is then starving for fuel. After a dozen attempts, it will finally stagger to life, and then idle just fine if I can keep it running at least 5-10 seconds. But I once ran a battery down in the process. Since the engine doesn't seem to want to stay running once it does start on the first few attempts, it makes me wonder if idle mixture is set too lean or if float level is low. Maybe it wants more than 10 seconds prime at lower temps? In warmer weather, the engine starts immediately. Any thoughts/comments appreciated.
