Fired her up on Satyurday after 5days buried under a foot and a half of snow....
Monumental backfiring, tractor noises, sounded like a bag of spanners. - hopefully I just had a slightly cold / stuck / sticky rotor.
After abouts 15secs of running (and a wee bit of right foot) all was well again.
Needless to say - i was bricking it!!!
Not just me then, although no snow fall here in Plymouth, everytime i start her up she is backfiring/popping away until she warms up then all is well.
