I just installed a brand new carb on the engine and found I could lean the low end quite bit more than what I normally had for the old carb. This really cleaned up the midrange but made it as difficult to start(initial) as it was before . So the next day at the field for the flight tests with the new carb I figured what the heck, I'll give the 5+5+1 a shot and at the very worst, I would have to remove the plug to dry it out. I was dumb founded when it started on that 1st flip and was just idling as pretty as you please. I then tried throttling up after a minute or so and I got a slight hestitation. So I opened up the low (ended up about 3/16 a turn more) and it was running perfectly and I also gained about 140 rpm with the new carb, I flew the airplane 4 or 5 more times that day and it started on the 2nd or 3rd flip each time without choking! My engine never started and ran this good since I bought it (used) several years ago. I think making sure the throttle is wide open on both of the "5"s is the ticket. Just have to (MAKESURE) you return the throttle to idle with the final "1" of the sequence with the ignition on or you could get yourself in serious trouble[X(]!
