Re: Aerovee one EGT high

Bryan, you didn't mention so I won't assume. You did verify both the top and bottom plugs are firing ok - right? Only one plug firing will give a hot egt as fuel burns slower and gets out the exhaust before it's ready. Brock, Mag check has been good. Generally I switch to the primary ignition only ...

Re: Aerovee one EGT high

Lou,
My #1 CHT failed. It reads around 100F after the engine warms up. Pretty much everything else was under 200F. It was cool out. Oil temp was 161.

Edit: I assume it has failed. I'm going to do a differential compression test today.

Re: Aerovee one EGT high

Another thing to look at is the intake manifold gasket security. if one bolt isnt as tight as the other, there may well be just one cylinder sucking air. I have saftied those bolts and have not had any of then come loose any bit. The other thing to consider is the probe may be at fault, if nothing ...

I'll check the exhaust gasket. They are the originals.

Plugs are coming out, stand by...

Aerovee one EGT high

Hey all, Looking for some thoughts from the Aerovee brain trust. I have one cylinder (#1, back left) going insanely high, like over 1500F. This is during a full power climb. If I enrichen it to get it below 1400, the engine runs poorly as the other cylinders are too rich. The others average about 12...

Re: EarthX Battery Kaput?

There is a solenoid in every relay. Our starter solenoid does dual duty, pushes the gear forward and makes electrical contact. I didn't sense any confusion here.

Re: New Tool

I save a few mandrels. When you need to drill out a rivet you can grind the end flat and use it to punch out the part of the mandrel in the rivet.

Re: Elevator Trim Linked To Flap Settings

From reading that I'd guess the starboard trim tab is linked to the pilot controlled lever, or there is no starboard trim tab and dial-a-trim is used. But it would be easy to implement, just a cable attached to the flap handle that would move the trim tab. Seems like a silly thing though. The PA18 h...
