Howdy again, Low 'n' Slow fliers-For those flying behind Continental A65s, what is the recommended idle RPM? I've got a rebuilt carb and will be setting the idle speed in a week or two, and need to know what these engines like.Thanks!Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Oscar,I have an A-65 in my other plane, an Aeronca Chief, and I have the idle set at 650 rpm. It runs so smooooth. A Continental A-65 is such a bullet proof engine. Easy to maintain. Easy to fix. Hardly ever breaks down. It'll run forever. The only "down side" is that it is only 65 horsepower and it doesn't have a starter (but, who really needs one?). It's a great engine for a Pietenpol!Irwin FustAnderson, CA________________________________________________________________________________

OscarDittos with Mike. I run at 600 after warm up for a couple of minutes at 750.Dick n.----- Original Message -----

Group,Having had a close association with the small Continentals, mainly those equipped with the Stromberg carburetors, for well over 50 years, I have found that 550 to 600 rpm at static idle is about right. The following procedures have worked well for me:It is important to warm the engine thoroughly and adjust the idle mixture first (idle speed to be adjusted later) by means of the big brass screw on the aft side of the upper carburetor body. With the engine idling (throttle fully closed) slowly turn this screw counterclockwise to enrich the mixture. When the engine begins to run roughly, it is time to slowly turn the screw clockwise to lean the mixture. As you do so, it is a good idea to open the throttle a bit to clear excessive richness, then close the throttle again and continue to slowly lean the mixture until the engine begins to run roughly. Then turn the screw counterclockwise until the engine idles smoothly (usually not more than 1/2 turn is required).You may find the idle rpm is now a bit too fast--especially if the idle mixture was set too rich at the beginning. Adjust the idle speed after clearing the engine with a short burst of throttle, and you should "be in business".To check the idle mixture setting, turn off the fuel with the throttle closed and let the engine idle until it runs out of fuel. Ideally, the idle rpm will increase slightly just before the engine stops.In our climate (Alberta, Canada), it is customary to increase the idle speed to about 600 rpm in the winter and enrich the idle mixture by 1/4 to 1/2 turn of the adjusting screw. Summer setting is about 550 rpm with the mixture adjusted as described previously. The Stromberg does not have an accelerator pump and the engine may quit if the throttle is opened too quickly when doing a gliding approach on a cold day. For this reason, we generally avoid power-off, engine idling, approaches in the winter. Of course, these precautions don't apply to you folks in the warm, sunny south!Graham Hansen (Pietenpol CF-AUN)________________________________________________________________________________Date: Wed, 04 Jan 2006 07:23:19 -0500

Winter in Canada - I'd start my old T-Craft, leave it tied up, and go backin for a coffee for at least 10 minutes. What else are you going to do@ -20C?Bob-----Original Message-----
