Static RPM too low

[DanBrown]

With full power, my A-65-8 will get a max of 1950 rpm. The TCDS says not under 2070. I had the prop repitched with no change. Both mag drops are equal at 20 rpm -- the carb heat works ok. What are some other causes to have checked? Thanks all..

Tachometer?

Re: Static RPM too low

try using an optical tachometer

also make sure you have fresh fuel

Mixture or mag timing, or a little of both. IF the tach is accurate.

remember the quick tach check , after dark, place the ship with the back toward a light, run the engine up and at 1800 RPM the blades will appear tostop. 60 cycle / sec you know!

Thanks all. The tach checks OK -- will look at mixture and mag next..

Timing and compression check too.

Must be a gas discharge lite like a mercury vapor or flourescent. Worked good for me at 1800 rpm.
