back fireing & a pain to start... any ideas on the following.. my 03 is a pain to start.. its obviously been tucked away during the winter.. its been plugged into a optimiser.. any thoughts.. would it be a spark plug issue... also to get ut started after about 5 pushes of the button, it will only start with through choke on full.. to add it sometimes backfires once it started?? is that because its cold?? what should i be looking at to prevent that.. any thoughts would be great |
