One of the line crew at York THV showed me this method today. He uses it before starting many of the fuel injected rental planes on the field, including several that have no prime capability. I figured that this morning would be a real test since my plane was outside last evening and cold soaked at around 20F.
1.) Turn on Batteries and boost pump…mixture to rich. Move throttle forward to full fuel and back to Off 3 times. Turn the boost off and batteries off.
2.) Hand turn prop through 2-3 revolutions
3.) Repeat step 1
4.) Hand turn prop through 1 more revolution.
5.) Prime for about 15 seconds
6.) START…mine started IMMEDIATELY with absolutely no coaxing. I was frankly amazed!
Hope it works for others having the problem.
