Tuning & throttle linkage adjustment

[marcobrien]

I've got an Acme Condor with .15 engine. I'm trying to tune & adjust the engine/idle speed (only has one adjustment needle & idle screw).

I think the throttle linkage needs adjusting, but I can only seem to adjust it to idle correctly or open full throttle. It doesn't seem to have enough travel from fully opened to fully closed. When I adjust, then accelerate/brake, the servo seems to push the carb back open slightly so it idles fast.

I've attached a photo of the linkage & carb. Any help/advice/guides would be greatly appreciated.

in this position the servo is in neutral? make your servo linkage "+" not "x" when you are looking at the photo. Cause the way you set the rod just moving side ways not traveling as push and pull .

It was actually set in the + position but I adjusted it in an attempt to get more movement in the linkage.

Once back in the correct position, what's the best way to go about resetting all the linkages?

 

[avelciario]

return it to the + position then adjust the stoppers of the linkage. Try to move the stoppers back and fort until you've got the correct adjustment

First thing I would do is get a new airfilter foam, the one in the pic you posted is way past its useful life.

A bad/overused airfilter like that will give no end of probblems when at or near idle.
