Since then I've never primed the engine unless I was cranking it over. No chance of an airbox fire, and always seems to work.
Good advice. Absolutely the safest method when using a primer.

Agree! And, yet another piece of good advice that's worth (much more than) the price of admission here!! Mac

Agreed... The best money I've ever spent. Great knowledge here.

Interesting in any thoughts about changing the air filter (Bracket type) for K&N and the effects on hot starting... Improvements or no change?

great ideas... Many thanks..

I'm never sure whether to prime or not...

I need to have a try and see what works best..
There should never be the need to prime (or choke) a hot engine.

Just a data point..........

It was over 90° F yesterday in Central Virginia. After flying for about 1 hour and making a brief shutdown/stop, I pulled the starter handle and the O-200 fired right up. No prime!

Cheers,

For me, in the UK with C85 engine and Stromberg Carb ( G-BVUZ) with Pull starter. Cold start. Power on, mags on, throttle full closed.Prime ( 3 pumps) Pull starter. Any start up afterwards and on hot days. All off ( power fuel etc). Pull prop through 3 times by hand - clears any vapour lock I am told. NO prime. Throttle cracked open no more than 1/2". Power Mags on . Pull to start. This has worked for me last 3 years including the very hot ( for the UK) summer we had last year. If I don't do the pull through by hand thing then often she simply won't fire up.
