Mike,You probably have done this, but number one, tie the tail down with a rope andknots that you would feel comfortable restraining a pit bull next to an elementaryschool playground with. Do not trust wheel chocks nor brakes. If it startsunexpectedly, your throttle and mag switch may not be set, and have a CO2 fireextinguisher on hand. 10 years ago a FL Piet project was largely destroyedon the first start for want of 6 feet of rope. Any engine that is giving troublestarting is a distraction, and is creating a situation that could lead to inattentionon the brakes.Two hours is a lot of hand propping on a warm day to not have a single hint oflife. Even if you don't know the starting drill on a 65 yet, in 120 minutes youwill have by random chance a pop over if everything is set right. Go back andcheck things. Popping over on starter fluid does not correct what is out ofadjustment. You don't need the motor to run to time the mags and verify floatheight.Now comes the stuff only a tactless person would say: If the guy who is teachingyou about hand propping a 65 doesn't already know every single thing that hasbeen written by Jack and the other's he is the wrong guy to be helping you.Hand propping and diagnosing engine issues are skills to learn, but if your guydoesn't know what is going on in 2 hours, you need a better in person assistant,or to have the realization that you are on your own. You can not imaginehow many people I speak to every year who are new to airplanes and have 'a buddy'who is just providing a false sense of progress and security while the stumbleon.Tactless part #2. If in any way shape or form, it turns out that your 'carb rebuild' or any of the adjustments to it are the starting issue, take it as a warning shot from the universe not to play aircraft mechanic on critical items. Sounds harsh, but read this story about a guy I knew who insisted that anyone could rebuild an airplane carb, that hubris and an internal mistake, killed him on the first flight: http://flycorvair.net/2013/04/20/risk-m ... -place/Not to hurt your feelings but your tone on carbs reminds me of Ken. I asked him3 times to have a pro check it, he died a week later.Any engine, Continental, Corvair or Lycoming, if it is set correctly should start near instantly on a warm day, even if it has never started before. The average crank time on a brand new Corvair at a College is 3 seconds. A perfectly set new 65 should light on maybe 5 blade pulls. Tactless part #3: if the best prep work you can do before a start test doesn't work, take it as an important sign that you need to re-evaluate what you think you know, and who you think you are learning it from. It should not take two hours of pulling on a prop and an email from a tactless jackass in Florida to have a 'moment of awareness' on this. In the past you have offered a lot of information for sale for a guy who can't start an engine today. I have been an A&P for 24 years, but I still touch every plane cognizant that safety is only found after you discard the myth of personal infallibility.
