Today I went to my archery club, a 25min drive from my house and parked up. After shooting 12 dozen arrows on a National round which took about an hour and a bit then chatting afterwards over a coffee, so after roughly two hrs I started the 80 to dense clouds of grey smoke.
Once the engine had reached full temp it cleared, but it wouldn't have been stone cold after standing for two hrs, but what could have caused it?
it's never done that before, BTW it is running on petrol not LPG at the moment.
On the way back home I tried revving it at the lights when at a standstill but no more smoke appeared.

and no trace of smoke 
, so why did that happen yesterday. 
, I've been to the LPG man this morning because the gas wasn't getting to the engine so was running on petrol all the time. A solenoid on the tank had failed, but the Flashlube system, which should 'talk' to the LPG system, was occasionally going potty and pumping too much Flashlube through, hence the clouds of smoke.
