Moderator DirtyDT Posted March 3, 2012 Moderator Share Posted March 3, 2012 Check where the petrol is stopping. If it is coming to the petcock, is it getting to the carbs? Are the carbs full of petrol? Is there an inline filter that is blocked. Have you poured a little fuel down a spark plug hole, refitted the plug and HT lead and then tried to start it?
