PAR 36 is a style, not a part number. 4313 is a part number. There were several automotive PAR 36s part numbers before the old glass...

Too little heat, and the engine will not produce rated horsepower, and it will use more fuel. This is why cars have thermostats. Take...

They have those high RPMs because the propeller is a fussy device. At 700 RPM, idle RPM, it will barely move the airplane. Double that...

It is. An injector nozzle looks much different, and has a much different operating principle.

That Lycoming O-320 has a max continuous rating of 2700 RPM and 150 HP, straight out of the TCDS. As I posted: And as I said, the...

Remember that the passengers are travelling in a straight line. Their momentum is along that line. If the airplane is suddenly forced...

The airframe manufacturers specify the propeller pitch so that in level flight, near sea level, the engine will reach redline at full...

Just try borescoping the case on a Lyc to get a look at the cam and lifters. Nope. Cylinder has to come off. There's no access. On some...

You lower the nose to maintain best glide, not to prevent stall. Have you done full stalls at altitude? Power on and off? The nose is...

I'd put a desulfator on it first. It will put a low charge on it in the form of a square wave signal that breaks up the sulfate and...

Just to add, the CamGuard only helps within the 30 day window of inactivity most OEMs use as a benchmark for when to preserve an engine...

An hour isn't going to do the job. At the very least, a magneto needs to come off to get a look at the steel gearing and mag drive...

Only if the airplane does not exist. My experience as a mechanic, dealing with owners who have ground-run their engines, tells me that...

I wasn't talking about the cam and lifters. I was talking about the piston putting more load on the bearings at lower RPM and higher MP...

RPM isn't the only factor. A coarser prop lowers the RPM but results in higher cylinder pressures, putting more load on the bearings.
