Hi Folks,
On my last few flights I've had a bit of trouble getting it started using the procedure that has otherwise worked for years (three shots of primer after feeling it firm-up, throttle cracked). I brushed that off since my primer has been getting a bit weak and each time it was after a period without running so the battery was possibly a bit low. Went flying this past Sunday after servicing the battery and with a solid primer and it started up without issue. Had a great flight but as I was enjoying a rare greaser of a landing it quit on the rollout. Naturally at this point the primer refused to pump (I might start a thread on that) but I was able to get it started with the accelerator pump. Taxied back to the hangar and it idled without issue. Possibly not as smoothly as could be but certainly nothing abnormal with or without carb heat. So now I'm wondering if the hard starting and the flameout are related.
I did a search here (and online in general) and found an old thread on the same thing for a C85 that mentioned the issue was corrected with a turn of the idle mixture screw. Unfortunately I didn't make a point of looking for the RPM rise as I shut down but I will do next time I'm out there.
So, short of checking for induction leaks and idle carb settings does anybody have any ideas what to check? I can see where the idle adjustment might work but I'm puzzled why this would manifest itself only recently. And what would be different about the rollout compared to sitting in front of the hangar?
Cheers,
Jeff
