Frans,

I had the same problem, albeit it occurred no matter if the engine was shut off for 15 minutes or an hour.

When my carburettors were rebuild last winter by Bert Spreuwenberg, it turned out that the seals were due (the engine was built in 1999). Though unexpected for me that solved the problem completely. I only open the throttle an inch or so for warm start and it fires and runs immediately. I hope it remains that way in summer when temperatures rise further.

I also found out, that I don't need choke even after hours parking and even at cold temperatures only for a few seconds.

Maybe I'm just only lucky but I wish you the same.

Update:
Frans, disregard my last post. I had the same problem yesterday at Bitburg. Temperature around 20°C. It was flooded and started very reluctant. After landing I discovered traces of fuel on the nose wheel spat. I also would be one of the first customers for a (reliable) fuel injection.....
