I agree with the procedure up to step 9. I was taught to start the engines differently after step 9( I was a mechanic on a fleet of DC6 A&Bs in the 70's)
10. Mech in right seat clears #3 for start.
11. Mech in left seat engages safety, primer, starter, and booster coil switches.
12. Mech in right seat calls out blades.
13. Mech in left seat switches mags to Both after 12 blades.
14. Mech in left seat releases start and booster coil switches after engine starts, but keeps primer engaged .
15 After engine is running fairly stable between 800 and 1000 RPM on primer only, mech in right seat sets mixture to autorich.
16. Mech in left seat watches for a 200 RPM drop(rich mixture) then releases the primer ( This is to prevent a back fire from a lean mixture if primer is released too soon.)
I used this procedure successfully many times. I have tried using it to start the PMDG DC6. Not much luck so far. Keep in mind, I am presenting a procedure from a mechanic's point of view. I absolutely loved my time with these wonderful planes.
