HI DAVE
IVE RUN THIS THING ON MOKI 18% OIL NO NITRO AND MY WALBRO ALKY MODIFICATIONS WORKED WELL. I HAD ADJUSTMENT IN BOTH DIRECTIONS - TO RICH & TO LEAN. I MADE A BATCH OF ALKY AND 40:1 KLOTZ TECHNIPALTE WITH 20% CASTOR IN IT. THINK ITS KL100. ON THIS FUEL ITS SO RICH I NEED TO ALMOST CLOSE BOTH NEEDLES. I GUESS ITS BECAUSE I NOW HAVE 16% MORE FUEL SINCE MY MOKI FUEL IS 18% AND MY NEW FUEL IS 2%. ILL HAVE TO DO ANOTHER CARB NOW OR MAYBE ILL JUST TRY 1 IN THE STOCK FORM SINCE CLOSER TO THE GAS RATIO IT MAYBE RICH ENOUGH WITH OUT ANY CHANGES. IVE HAVE ABOUT 2HRS ON THIS GLOW PLUG SO ID SAY I DONT HAVE TO MUCH COMPRESSION. IM TURNING AN 18-6 MASTER CLASSIC AT 8400 WITH THE OVER RICH CARB.
