Carb Throttle Return Spring
Setting up my first Warbird Gasser, using a DLE55; I can figure the throttle and choke servo and linkage out easy enough; one question: do you remove the throttle return spring, or leave it on?
Thanks. |
RE: Carb Throttle Return Spring
No real need to remove it.
If the servo dies it's, in most cases, not strong enough to over power the servo, but if the linkage popped off it would shut down the engine |
RE: Carb Throttle Return Spring
Leave it. Remove the idle stop screw completely, and make sure it has an NGK CM6 spark plug in it.

Actually you want to leave it but clip the little tang that engages the bell crank to return it to idel. The idea is that the sprimg remains to push out against the carb body to avoid vibration wear on the arm, but with no back pressure on the servo.

I do what Steve said.

RE: Carb Throttle Return Spring
I unclip the spring but I don't cut it like steve mentioned. There have been times I wanted the spring to operate and if you clip it then you may someday have to buy a new spring.;)

Another quick question; what are your thoughts on Throttle and Choke Servo selection; Standard Analog servos OK to use?
|
RE: Carb Throttle Return Spring
For the choke just any old standard. For throttle it depends on the plane type.I like at least duel ball beraing servos for smoothness, they doen't wear over time. For stunt planes I look for speed, throttle doesn't require a lot of torque. In my larger stunt planes I have used fast lower end digitals.
