Starting 1ES

Pilots,

I have seen numerous "failed attempts" to start Cessna 1ES, and to a lesser extent, the same problem applies to Cessna 17J and Piper 85Y - which is, fuel-injected lycoming engines use a weird approach to starting.

For warm weather (read: always), the procedure in the checklist will FLOOD THE ENGINE every time. Here is my procedure:

Master ON
Mixture to idle cut-off
Throttle in 1"
Engage Starter until engine "catches", no more than 10 seconds.
Mixture full

If the engine failed to catch, try the boost pump for 1-2 seconds and repeat.



That's it. Using the primer/fuel boost pump should ONLY be necessary when it is cold out, and even then, do not use the 5-seconds or the "until fuel pressure stabilizes" rule. That is for Continental engines. 1-2 seconds TOPS will suffice.

Starting with the mixture "full rich" like the carbureted planes (68U, 20U, 04H) is a recipe for flooding also.

Give it a shot -- if you have a particular "trick", I'd like to know. At $500 apiece, starters for 1ES are worth sparing. :)

Blue Skies,
