Thanks Nathan. For the manual AND the girls!

And since I'm never one to avoid looking a gift horse in the mouth, any chance you have a pilot's manual for a 7EC?

Fantastic! Thanks Nathan.

Did this to ward off the spammers (Joe A)

Does anyone know where I might find a 7EC service manual in electronic format? I found the paper version, but being a Champ pilot, I'm a cheapskate .

Jimmy, I did all the work in my A&P/IA's shop, and I used his flaring tool. For some reason, his tool doesn't make flares very cleanly. I even spent some time deburring the tubing before I flared it, but the edge of the flared end was still just a little rough. I expect that's just because you'r...

Thanks for the information. I went out this morning to work on it, and I found that by unclamping the tubing and re-routing it some, I could just manage to get another inch or so of reach. So I was able to cut off the cracked part, flare the end, and put it all back together with some new clamps on ...

I recently had to repair the fuel shutoff valve in my 7EC, and while taking everything apart, I found a crack about one inch long starting at the flared end in one of my fuel lines, the upper right line shown below with the obvious leak: http://img213.imagevenue.com/loc596/th_18661_IMG_2920_122_596l...

Thanks for all the info guys. Dennis - I have the carb icing probability chart myself, and based on the conditions, I think it was extremely unlikely. It shows that the probability of carb icing was about the same as it would have been in cruise on a 100 deg day with 20% relative humidity. If carbs ...

Thanks again Mark. I just sent ACA's parts department an email before I saw the two part numbers you came up with. I sent them my photo, so I'll see what they say.

Thanks Mark, that's good information! I really didn't think a leak like that could cause it to stumble, but I'm looking behind every bush right now. And you're probably right about how long it's been leaking - I've smelled a faint fuel smell in the cockpit for as long as I've owned the airplane (6 y...

Recently the engine on my 7EC "stumbled" in cruise. The stumble was a short, but attention getting drop of several hundred RPM that lasted for 3-5 seconds. The conditions weren't right for it to have been carb ice (80 deg day, cruise power, low humidity). After the power came back up I did...

Check the Autolite plugs if space is tight - they are shorter than Champion. Good to know Mike, thanks. I'm getting ready to order the harnesses and plugs now. The plug I bought just to check the fit was a Champion, and the fit was tight, but ok. The Autolites are a little cheaper, so I was plannin...

Thanks, that does help Jimmy! The plug is clearly shown as being approved.

I think to use them (and clear the cowl), I'll need a new ignition harness. My current harness has hard elbows that don't clear, but I tried an old slick harness with pretty flexible wires, and it fit fine.

Thanks again.

My 7EC has unshielded plugs (M41E's) in the the top of the front cylinders. They sit inside what I think are called "Ercoupe caps", and I've always had problems with these plugs. I've read here about folks using the shorter REM37BY plugs in place of REM40E's, so I bought one and found that...

Moved this to the Engine section where it should get more people viewing. As well would like to see the photos. I have only the screen now and was thinking of putting a filter on my C85. Thanks for the info! Joe Joe, since Nathan volunteered to post the photos, I'll forward them to him, but could o...

I received this from a friend the other day. He has a C-140 with an oil filter mod on his C-85-12. I couldn't figure out how to show the pictures, but they were dramatic. --------------------------------------------------- Or, how NOT to save $2.50! Last year I had my Cessna 140 on display at a Cess...
