The original gear was the weakest of 3 or 4 Maule factory designs and sure enough it was bent making the plane sit left wing low since I got it.

Well, I finally got my new gear, brakes, wheels and tires installed. I think I love it... just gotta learn how to land it now!

Nice!!!!!!!!!!!!!!!!!!!!!!

Gump

too cool

I like it!

Just great when Santa knows what you want, you have been good, and he comes early.

Those look too big to fit down the chimney!

You are my hero Nice lookin bird.

Looks awesome, Spinner. Is that a 220 powered M4?

Thanks y'all for the encouraging words! Glad to see it's a hit.

Yes 01V, my M4 has the 220hp Franklin in it. Good power and last tank it burned just 9.2 gph.

did you buy a big jug of armour all to go with the tires?

So my 12 yr. old son and I decide today would be a perfect day to practice. We're both excited. Weather's nice and the first three landings around the patch are sweet as candy. We then head off to land at a friend's ranch and various other places.

About twenty miles out we clear the Caprock and I notice a shudder... then another. Hmmmm, weird. My son doesn't feel it, but I do, so I start a turn and now it really starts missing.

I aim back to the west hoping it will run long enough to get me back on the Caprock where there's plenty of cotton fields to land in. The engine surges while running roughly, but it's still running. Everything's in the green. I go through my check list and try everything while nursing as much altitude as I can staying a little above Vbg.

Finally it stops surging and just runs terribly rough. .. but it's running. I see the #6 cylinder is reading 740 EGT. The rest are all about 1200 now. I guess it to be a bad cylinder.

I make the turf runway at my home airport, grease a landing and taxi up to the hangar.

Wouldn't ya know... The plane and I were feeling great up to that point and I was loving the feel of the new landing gear, anxious to fly a bunch.

Bummer... but all is well. I'll know more next week.

I'll display my knowledge of a Franklin are they fuel injected? because what you describe sounds like a clogged injector or maybe a stuck valve.

Carbureted. Stuck valve seems likely, doesn't it?

if its just your primer left unlocked, its happen to me..duh.. makes em run real rough too. woody

Simple compression check will tell the story if it's a valve.

Could be a bad plug, too. Maybe start by looking at the plugs in #6, if its a wet one and looks like it has not been firing, put another good plug in and give it a try. (you can fire it up with the cowl off for a few minutes to see if it runs smooth) That happened to me once and I carry a spare now. Inspect the plug wires, too. If #6 is grounding out it could cause that symptom. Those are some easy things before getting the A/P on it. Good luck, hope its something easy. I've had to clean the screen on my computer several times to clean up the drool after looking at your photos...nice job!
Best wishes for the Holidays and your solution,
Don

I'm not sure why, but a bad plug will cause an increase in EGT. Watch your EGT during your next run-up, On one mag, therefore one plug per cyl., your EGT will increase.

I don't have such sophisticated engine instruments...strictly stock. But I would like to know "why ?" Does it matter if its top or bottom?

No, it doesn't. I assume that less efficient combustion results in higher EGT. That doesn't make sense does it? I know that the lower compression motors run higher EGT's. Example carburated O-540 vs I/O-540. I assume the lower compression is less efficient and that is why the higher EGT? I do know that if you ground one mag in flight, you will get a decrease in power and an increase in EGT's. Go figure, they seem opposite don't they. I would expect a drop in both power and EGT.
How do you lean without an EGT gauge?

No big deal, do it by ear. I lean to rough, richen 3 clicks. Before you mention it, I got no idea if that's lean of peak, rich of peak, or peak. Or maybe don't peek.
My first airplane had an EI CHT/EGT gauge & I leaned it by ear too-- trying to read that flickering digital display was a PITA.
I'd venture to guess that there's more airplanes out there without an EGT gauge than with.
