I just installed a new 140 in my Synergy. Had 90 flights on the original and sent it in for new ring, and rear bearing.
I ran one tank of PM 25% thru the engine on the ground, cycling between lean and rich.
Then I put it in the air, still a little rich. I had forgotten how much power this engine produces. Noticed it while trying to taxi. the slightest movement of the throttle stick had a great response at the engine. I could not taxi without "pulsing" the engine.
It flew fine, but after landing, the engine would not shut down. It just kept clicking over shaking the plane horribly. A quick bump of the spinner with my hand stopped the determined engine. When I got home I adjusted the throttle expo to flatten the curve on the low end.
Tonight I put on the 2nd flight. Neither problem was solved. I still had to pulse the throttle to taxi, and it would not shut down.
I use the 3 position switch on the Futaba TX to go to low idle, and cut off. Always worked in the past.
I am thinking that there is something wrong with the carb, and may try putting the carb from the original engine on the new one.
Anyone have any other ideas??

Oh, the good ole days...
Back when I was about 12 (1971) my dad traded our Honda 90 for an EK Logictrol (Log 2)..it had humongous servos, plugs and a shorting plug for a switch.
Memories...
We learned to fly on the old Styrofoam Canyon Schwiezer 1-26 sailplane on Hi-Start ($29 from Tower I think). First flights yielded 1 traffic pattern from a 300 ft launch..I remember something like 30-40 second flights.(IT WAS VERY HEAVY) Then I'm back chasing the hi-start parachute. (Yep, I earned my flight time!!!!) Dad then extended the round trailing edges that came out of the mold by using balsa trailing edge material and we picked up a few more seconds per flight..then sandpaper and elmer's white glue to smooth the wing surface..a few more seconds. I think we finally got it to about 1:50 avg flight per tow. In contrast a couple of years later we bought one of the new EK Champions with the little bitty servos..built a Windfree and got at the very minimum 5 minute flights from the hi-start in dead air.
Why does it seem that RC was just as much fun then as it is now...(I would never have dreamed of having more than one setup back thenJ)

Anybody......remember the shorting bars we had made from a wood dowel and plugged in to turn on the receivers in the "50s. I had one on my J3 Cub BCR10 Babcock system. My 1st RC plane.

Agree, a mechanical/electrical connection sort of thing would seem best.
And have it located to be easy for all to see.
Later, Ron Lockhart

I personally witnessed an instance of electric starting unexpectedly at the Nats. Since I was only around Masters & FAI I believe it safe to dismiss the problem as lack of experience.
I feel it essential to implement some kind of safety device to prevent this from occurring. I would prefer a mechanical lockout of some sort or at least an arming plug.
The airplane was being carried back to the pits when the failure occurred. The handler was on top of the problem but it could have happened after the plane was parked.
It is a disaster waiting to happen.

Another reason to go electric.

I have an $8000 left thumb. They installed a couple of options while they were rebuilding. It warns of weather changes and also serves as an alarm clock (sometimes).
I recommended that a student headed for a pro basket ball career give up RC until the career was behind him.

About two years ago I got my finger in one It cut the right index finger off at the first joint. Wrapped the finger in a towel went to the hospital with the severed finger, three month's and $6000.00 later it was almost as good as new except it is still numb on the end. APC's show no mercy.
