Hi Bill: Seems as if we have a bunch of good old K&B boys here! I have had one some where in easy reach since 1949 & thought they all were runners ,(maybe the Infant was a little weak) . My favorite combo was a Sterling Lancer with a 1969 or 70 Perry carbed .40. Used to run it out of fuel about 1/2 the time & watch it windmill dead stick when landing, a bit un-nerving at first. Used to fill the tank , prime the engine flip it once or twice & put the prop just past TDC & let it set , when it came time to fly just putting the glow heater on it would start about 1/2 the time! Real neat! Have you tried that or had it happen? MAX H.
