Well, I should have listened to all the tips on RCU about mounting 2 strokes inverted. I tried to get away with mounting my TT pro 25's inverted in my C160 because it looked better and less of the cowl had to be cut away. I finally got around to firing up the engines to break them in and I had nothing but troubles. The fuel would literally pour down into the carb and flood the engines out. I tried flipping the plane upside down to start them and this didn't help either. I also tried different glow plugs- including those with idler bars and this didn't help either.

Long story short, is I went ahead and ripped the engines out and took the nacelles off and am starting over. Needless to say, the nacelles were attached pretty good with silicone and I pretty much destroyed them in the process of taking them off- not to mention I did a small number on the wing too. THe wing can be easily repaired and I re-ordered some replacement nacelles from AK models.

Lesson learned and I won't do that again. Now I have to start over with the engine install- which was a royal pain in the ***** to begin with the first time.

Why rip out the nacelles? I don't understand. All you had to do was turn the engine mount over 180 degrees. At most, maybe re-drill the holes, but I doubt even that. Maybe a new cowl, but certainly not redo the entire nacelles. Sounds like you had tank position issues more than anything...

I wonder if you could have left the engines and tanks and cowls alone and just installed the Cline regulator instead?

I should clarify- i didn't rip out the entire nacelles. I did have to rip out the entire nacelle covers, which I had secured in place pretty good. I was hoping to be able to turn the mounts 180 degree by only taking the small engine covers off, but I could not. As a result, i had to pull the entire fiberglass cowl covers off which damaged them in the process. Anyways, AK models was kind enough to ship me out the replacement parts so I should hopefully be able to try this out again.

kmot, yes I could have tried the regulators, but there is limited room in the nacelles anyways and I wasn't sure they would fit. Not to mention that a pair of regulators would be much more money than I want to spend. Those regulators would have been more money than I paid for these engines brand new.

How much were the Cowls, I started setting mine up for glow and had already cut the first side when decided to go Electric. Thanks...Don
