The cylinder that exhibited the failing piston was an O/H superior with a new piston and ring set from Fresno. History of the cylinder before the O/H was unknown to me. The cylinder was standard so the O/H was limited to the valves. That cylinder not only had the failing piston, but also showed some...

Up date to our cylinder problem. The piston in No. 2 cylinder failed. There was a chunk out missing between the top two compression rings. This was a piston with about 150 hours. Purchased from Fresno. Now trying to determine why it failed, whether from heat or if it was a freak thing that the pisto...

Thanks for responses so far guys. Going to start taking it apart tonight and see what we find. Would one cylinder going bad and its associated blow by cause the others to glaze like that? If thats not the case we have something different. I'll update on what we find.

Oil was changed to Aeroshell W100 this past summer after running Aeroshell mineral oil for the last 50 hours to seat the rings on the last replaced cylinder. Pretty sure we are not mixing rings as the cylinders were not all changed at the same time and three of the four cylinders that went bad were ...

Hello guys having some cylinder problems and looking for opinions... Engine is a mixmaster Top Overhaul: 4 superior steel cylinders, 3 are new out of the box, one is older with new valves, all standard. Two cylinders are continentals chromed to standard. oldest cylinder has 250 hours, newest about 5...

What was left of it points to mo gas. The bit of fuel that was in it had turned yellowish and had a bad smell. Now have several trouble free hours on it since cleaning the carb. We run mo gas in ours as we can get ethonal free near us but if one of the airplanes has to sit for any reason for a while...

Our crud was from sitting I have no doubt. Gas that had varnished. When we bought the airplane we had drained the bowl. We also emptied the tanks and nothing has been showing up in gascolator strainer. In hindsight guess we should have just pulled the carb off and cleaned on the bench rather than th...

To my knowledge all of the model 20 fiberglass taylorcrafts used the continental 0-470. The original 15 which was then modified into the prototype 15A was engined with 150hp Franklin. Taylorcraft then became concerned about the availability of the Franklin and so made provision to engine the airplan...

Glad you found the problem Ryan and shared the solution with us. And a four-place Taylorcraft is a very rare airplane that most people don't even know exists. I've only seen one! I believe around 20 were built, is that right? Russ Farris Pretty close. There were two 4 place Taylorcrafts. The first ...

Well this weekend the carb came off. Upon opening it up there were floaters in the fuel in the bowl and one piece of crud that blocked the left passage from the bowl to the jet. We cleaned everything out and reinstalled and she ran great today. Thanks everybody for you ideas and help

Thanks for the suggestions guys. The spark plugs are brand new so ruling them out (the old plugs were a problem). We are going to pull the carb on Fiday and go through it this weekend. Will also check for induction leaks before pulling it off.

Hello, my name is Ryan. My Dad and I recently purchased a 1953 Taylorcraft 15A Tourist this past summer. I am posting this question here because it has a Continental C-145 engine, and all Cessna parts firewall forward. Here is the situation. Our engine is running rough especially at higher RPMs 2350...
