Hi All,
I'm trying to develop a 'foolproof' hand starting technique for my C-85 equipped J-3 Cub (with Stromberg carb.) that will work across a full four seasons here in the northeast. I've only owned this Cub for about 2 years, and I've gotten pretty good at starting it, but sometimes it can be a rear bear to get going! Most often this seems to be when the engine is a bit cold, but the outside ambient temp. really doesn't really justify preheating. My general starting technique is to turn on the fuel valve, crack the throttle a bit, and pull the engine thru a few times with the magnetos off. In the warmer, summer weather, I generally don't use any prime, and she fires off in 2 or 3 good pulls. As the weather starts to cool, I generally give 1 shot of prime after pulling the engine thru a few times. Mostly this works, but a few days ago it took 15 minutes and another shot of prime to get the engine running. I'm always reluctant to prime too much for fear of flooding the engine, but clearly it needed more fuel this time!
So, what are the 'foolproof' techniques to starting a C-85 in differing temperature conditions? This is a strong running engine with a carb. that was serviced by Uni-Tech ('the Stomberg expert') about 100 hours ago!
Thanks,
John
