After nearly a year and many flights, I am yet to find a reliable, repeatable cold start procedure for my carburetted F23.
Warm starts are fine- crack the throttle a bit, no choke, and it fires within a couple of seconds cranking.
But cold starts are still a mission-
My routine is usually squeeze bulb until I feel back pressure to ensure the carb bowls are full; throttle at idle; choke on; mags on; and crank.
Very occasionally OK, but most times I need 5-10 x 5 second sessions of cranking with/without choke, various throttle settings; and when it fires definitely requires throttle and some choke for about 5-10 seconds to settle it at about 2000rpm for warm-up.
That seeems to indicate not enough priming.
What procedure/tricks do you guys have for starting?
