My 3800 starts from cold easily but when warm it is sometimes quite difficult to start. Can anyone tell me what the problem could be.
<br>Thanks David

that seems to be inherent to piston engines..my solex ('65) starts best at the first run of the day.

Many times the engine runs rich due to the evaporation
<br>of petrol that continues to evaporate after you shut off the engine.
<br>"priming" the engine by repeatedly applying the decompression lever while pedalling and starting the engine most of the time overruns this enriched state.
