Played with the thing again last weekend and the problem is definately to do with the choke. Had it firing up all day but once it gets a bit cold it will not start unless I force the choke closed more. As i said previous adjusting it closed more only leaves it running too roughly to get the vacuume to work and it just hunts along. Bruce i did remove the main jet completely to look for an 'O' ring but it doesn't seem to have one. Also as fast grass has suggested ,once I thought I had it running sweet I covered the thing in nail polish wich hopefully sealed it as well. Does anyone have any ideas with the vacuume thing,a sring maybee??Cheers Greg
