Chris,

I know that each engine/installation is unique, I usually don't have= to prime even once when cold (summertime), and never when hot (doesn't n= eed the extra help igniting the fuel mixture). However, I always go= rich on the mixture knob (full rich for a cold start, 2-3 o'clock position for a warm start). It a= lways starts within a few seconds of cranking. I would try priming l= ess when hot and see what happens. Also, I would check your idle mi= xture settings. If it takes that much priming, it sounds like it may tuned be a bit on the lean side.

My take on your static rpm question is that OAT may be the= cause of the variations. Sounds like you've got enough to get off = the ground. Have you done any fast taxi runs? You've got plen= ty of runway.

Thanks.
