I do not see where that is a Diesel. There is no lavonia cell anywhere to be seen, it has glow plug in it.

RE: 4-stroke diesel
I just got through test running my Magnum .30RFS after a diesel conversion. The engine itself has some kind of issue and won't hand start but it ran OK after starting. I have to tweak the compression ratio and make some changes to the lanova cell, but it works. It throttled well after adjusting the needles. Now, I have to go back to my OS FS-40 and make some changes to finish that one. I might get a video of one of the two running this week.

RE: 4-stroke diesel
So someone get's a glow plug engine in the wrong diesel box and makes a huge profit on ebay. I wonder if the other box was used to sell a rare nitro enya, with a mysterious compression screw.

RE: 4-stroke diesel
This is my OS FS-40 converted to diesel with lanova cell. It runs OK. I have too much compression and need to reduce it. That's an easier problem than increasing compression. I hope to get some tach readings tomorrow.
Edit: It has no rocker cover at this time because I haven't shortened the pushrods. The adjustment is at it's limit which gives proper clearance, but the adjustment screws hit the cover while installed. It'll be back when I'm done.
The Magnum .30 RFS still has valve sealing problems that I haven't sorted out. It runs but is inconsistent and will not hand start. I might try the other one I have to see if it's any better.

RE: 4-stroke diesel
treedog, If Drone is on the front of the crankcase it the MkII version with ball bearing. If Drone is on the side of the engine it is the first version with a plain bearing. Needle valves and other reproduction parts are available from AEROELECTRIC email [email protected] specify the version Drone you have when ordering a needle valve as they are different from the plain bearing and ball bearing models. Also a variable compression head is available from Aerodyne. I have been running 3 of these late 1940's diesels with fixed compression heads and the Aerodyne variable compression head.

RE: 4-stroke diesel
I made it on my lathe. This one turned out very nice. The first one was so, so. The screw and contrapiston shot across my townhouse complex as the threads failed.
I ran my OS FS-26 yesterday on diesel. That one worked very well, and am happy with the results. The .40 still needs some tweaking so no tach readings yet.

Here is a video of my OS-FS26 diesel. It turns a Graupner 10x6 at about 8700 and idles at 3000. I saw some readings at 91-9200 but it could use some tweaking of fuel mix. It burns very little fuel.

RE: 4-stroke diesel
Thanks for the video, Greg - that 4-stk diesel sounds great.
In general (not in this engine) I wonder if threads on the inside of a Lanova cell could encourage pre-ignition. Hot, sharp edges.

RE: 4-stroke diesel
There are no threads inside the lanova chamber. But I do seem to think detonation is a problem. Jens says reduced ether will fix that. I'll be mixing some fuel today. You can here it knocking a little in the video, especially during throttle up.
