The IO360 on my Arrow 200 lately developped some rough running issues at idle.
It almost always happens during the idle check at the end of a run up.. I captured this in my datalogs attached.
The log in #1 shows how erratic my EGTs get right after a runup, with cylinder nr1 EGT being the worst. Fuel flow drops to just about 1.3gph and the EGTs are all over the place. The log in #2 shows how the engine used to run about a year ago where everything is looking smooth and fuel flow at 1.7gph. Both logs were made with same mixture setting so I am not running it excessively lean in the first picture.
Full rich, fuel pump ON/OFF does not fix the problem. The only way to stop the roughness is to increase throttle a bit. I dont suspect induction leaks because the engine idles really nicely after a flight. Roughness only happens when the engine is cold.
any ideas what to try next for trouble shooting?
I live in Naples Florida and recently purchased a 1981 Piper Dakota. Can anyone recommend a good maintenance shop for my annual?
The french control ask me to justify by a SB or other that the electric pump 481-666 of my PA 28 181 is "on condition".
He want to know if this pump...The french control ask me to justify by a SB or other that the electric pump 481-666 of my PA 28 181 is "on condition".
He want to know if this pump have or no a limited life ?
Somebody can help me ? Show more
I believe the shunt may be internal to the ammeter gauge in which case installing an external shunt with the regular gauge would show the symptoms that you have.
Exactly! And that diode went bad. A rather expensive part to replace.
Thank you, my mechanic said that there was no shunt either. He installed a shunt and a 60amp breaker as well as a new ammeter gauge and I still cannot get any load on the ammeter-needle all the way to the left even with everything on. Alternator tests ok, battery ok. He also adjusted voltage regulator.
Hi Stan; Thank you very much. I never knew that. Very good to get that piece of information in the data base.
glad your taken care of.
I happen to remember the early taper wing single engine Pipers used a large diode on a heat sink instead of a 60A circuit breaker. It is installed between the ammeter and the master relay on the 6 gauge wire. I just verified that by looking at an early Arrow wiring diagram - I don't have a Warrior manual.
Got it from Western Aircraft. Good guys , good to deal with. Ask for Eric.
Installed and working perfectly.
Old switch barely held gear up. New switch at 1800psi . Could hardly pull gear out of well with aircraft on jacks. Hope this helps others with similar issue.
Thanks for all the input.

Thanks, Steve. We have the GLYD seals ordered and hopefully on their way!

Dear Mr. Dellenbusch,
The ”Hutch” modification to the Pawnee using the Cessna spring steel gear was from quite a few years ago and is very difficult to find information about. Charles, our airframe shop foreman, had to really hunt to get information when we last worked on a Hutch Pawnee. He ended up talking with Mike Hutcherson in Texas, and we were able to buy a blueprint from him for the gear installation. We still had some problems as someone had modified the original installation(which was not a good design), but we were able to get the gear working again. Charles thinks the person who now owns the Hutch STC is in prison, so that may be why you cannot contact him. If you want a copy of the blueprint we have, we will charge you what they charged us, $210.
