Cub 099 diesel?
I have been looking to acquire one of these, but have never seen one. .049s and .074s, but not the .099. Did a diesel version exist in this size?

Larry,
I'm no expert, but I don't think there was a .099 diesel. I know how I can find out though and if no one comes up with a conclusive answer soon I'll check on it.

RE: Cub 099 diesel?
Dennis,I have a CUB 0.074 Diesel bought new in the 60's,that I have never been able to get to run longer than a prime.
I used OK diesel fuel back then and later tried Davis fuel which ran well on my Davis conversion Cox 0.051TD.
I have Davis 1/2 A fuel which i bought last fall and have not tried yet. Do you think the fuel needs more ether and/or castor oil to run in the CUB?
Thanks in advance for any or all suggestions and advice.
P.S. I have an AM 1.5 cc which ran very well with the OK and Davis fuels in the mid 80,s.

RE: Cub 099 diesel?
mapnet,
Next time you try the Cub, check that there's no air leak around the needle.
I used OK Cub diesel fuel in the 50's. I think others were McCoy and Topsol (Francisco).
Now I use Davis and Aerodyne. I have not yet used RedMax but I understand it is good also.

RE: Cub 099 diesel?
On one Cub .049 diesel, I had to replace the O-ring. I found an O-ring supplier, and went in to buy 1, count it 1 ring. He just gave it to me <G> The engine worked just fine after that. Smallparts.com has Viton rings that are about the best for high temperature and chemical resistance. Sorry, I don't recall the size.

RE: Cub 099 diesel?
[&:]OK, so shoot me if this is a really dumb question, but could you mean a McCoy "9" diesel? I have one, and I was squirreling around the net trying to figure out how much it's worth before I post it for sale.

Check the needle valve assembly that it isn't blocked also. do not use too big a fuel line on these use the smallest tygon or buena rubber that you can. However to check this out cheaply go and buy some cheap plastic fuel line at you friendly pet/fish supply/hardware store. easier to see what is going on. Make sure that it really makes a seal on that fuel nipple.

RE: Cub 099 diesel?
Remember to not use silicone fuel line. Diesel fuel makes silicone swell and may cause you to lose the tight fit.
What size prop are you using? Try a minimum of 6x4 and possibly a 7x3.
Also, you might start using a choke prime to start it. Using an exhaust prime may cause you to start the prime but not have enough compression to sustain firing after the prime has run off. Many diesel users compensate by increasing compression while the prime is firing...assuming, of course, that you are getting fuel.

RE: Cub 099 diesel?
Nope, not the McCoy 9 diesel, that is a whole different engine. And a pretty good one, so far as I know. I have helped a friend run his on some fuel we Jinned up from starter fluid, kerosene and castor oil, since he didn't have any good fuel. It ran just fine.
No, I was (am) interested in the Cub, but I guess it doesn't exist. I do have the .049 and .074 Cubs already.
