Default Diesel engine projects

OK guys, I finally got myself a digital camera. This will be my first attempt at posting some pics.

One of my first diesel projects was turning an MP Jets .061 into an .078. This was done by stuffing the piston and cylinder of the Hornet .09 into the Jets case. This was not too hard to do as the Hornet's cylinder has a very thick cross section and all I had to do was turn down the OD to fit the case. The original rod was used but the top of the piston was trimmed. This was done to ensure that the timing of the original .061 was maintained. I'm happy to say that the project was quite successful. At a slightly lighter weight than the original, I now can run a larger prop with a lot more power. Power is on par with a dieselized Norvel .074, but the Norvel is slightly lighter. Throttling with the Jets own unique, two needle throttle, is very good and again, on par with the Norvel. This project was completed long before I had dieselized the Norvel. Otherwise I wouldn't have bothered. Still, it was fun and I learned a thing or two about diesels.

What do to do with the parts from the original .06 Jets? Waste not want not, I promptly stuffed those into a collection of Wasp and Norvel .061 parts gving me a more compact .061 with nearly the same power. For some reason, even though the critical parts are identical to the Jets original, this one is hard to start,,,, even on 50% ether fuel. Also, for some reason, throttling isn't as good. May need to install a Jets throttle to this one.

Before I bashed the Jets .061, it was run as glow and I must say, it was a very strong runner and throttled very well. It's a tad on the heavy side though, as its genesis was as a diesel. All parts are built to diesel standard and we all know that's a virtual necessity. Never ran it as diesel but I've seen it reported that it's a good performer in all respects. An engine perhaps overlooked by most.
