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.

I can see the writing on the wall between Andy, AJ, and randy I think its only a matter of time
before one of these guys cranks out or modifys a 4 strk head to run the engine as diesel
somebody reported that they had a saito(Dave??) that had such a high compression that
it did run as a diesel but sounded bad after half throttle not being able to adjust compression
(overcompressed?)

What do you think Andrew, should we give it a shot? Could be interesting. Almost sounds like a challenge to me.

Andy,

Did you use the same conrods or retro fit the larger ones too?

Randy,

Your question prompted me to have a look inside both engines. Both were done several years ago and memory isn't what it used to be. [sm=confused.gif] Inside the Jets hybird is actually a custom made rod from solid bronze. It appears identical in length to the original Jets rod. Can only speculate why I did this but being short of rods comes to mind. I have another hybrid Jets which also has an .09 piston and cylinder installed but this one is run as a glow. It has the original rod so it looks like I got the two mixed up.

Also, while I did turn down the OD of the cylinder, I see that I also had to turn out the case a bit to make it all work. Would have made notes if Ida known I'd be posting pics on RCU some day. [sm=rolleyes.gif] Ah well.

The Jets/Wasp/Norvel hybrid has one of the early Norvel rods with the rectangular cross section. Wish I could get more. Experience has shown that they're stronger than the current "round" rods and that's a plus if you run a Norvel as a diesel. Wish Norvel made ALL their rods a lot fatter. Not a lot of extra weight added and it sure would help us diesel converters.
