Thanks to all for your responses on the Norvel. Now I know I'm not alone with this apparently fussy engine. I've heard good reports about the .074 diesel Norvels, but not as much about the .061. If increasing the oil doesn't do the trick then I guess I'll try the 40/40/20 mix since my engine seems to like it so much. Admittedly, my .061 is a bit of an oddball. It is a UC converted to RC with an AP carb. It runs like a banshee on glow.

Greg--I just assumed the non-ether 20% in JD starting fluid was hexane as other fluids seem to use it. Whatever it is, I just counted it against the kerosene. I have a question for you about lanova cells that is off-topic for this thread. I'll send a PM.
