If it ain't broke, don't fix it.
Well, it didn't seem to be broke but now I don't know?
Finished the annual on my Tu-holer and while it was apart I decided to weld a bracket to hold the end of the Throttle cable in the front pit Like I had made for the Acroduster. Throttle was working fine and as I did the inspection I found it was fully closing and opening but I wasn't happy with the clamps I had holding the cable end.
As I continued to work on it checking travel It started being very hard to open....... I spent all day on this thing.... I did weld on the new bracket and figured it would be the fix but it wasn't.
I found that it was the accelerator pump that was causing the issue. After the throttle is cycled a couple times the pump seems to "load up" and it is VERY hard to push the throttle to full open. Is this normal? If so, it seems I don't understand how this thing works?
Again, it was working fine. The carb was working fine on this engine in my EAA bipe but I had it rebuilt with new float when I put it on the Spezio. It now has 55 hours on it since rebuild.
Again, if I push the throttle slowly it will open but the accelerator pump gives high resistance toward the end of travel.
Don't know if it's broke or not? I have not run it I wanted to "run" it by you guys before I put the cowl back on.
Thanks,
Jack
