stork955 Posted December 14, 2009 Report Share Posted December 14, 2009 Gday, does it run OK on the choke and then play up when you turn it off then? Cheers, Stork Quote Link to comment Share on other sites More sharing options...
coop Posted December 15, 2009 Author Report Share Posted December 15, 2009 Hi Stork,it litterally only needs choke when cold but then only for a split second as it dies otherwise,she ticks over perfect though as soon as the choke is off.I did try useing the choke when she was hot and starting to die but that made it worse and the engine stopped,as this is a new fault(one of bloody many,this will teach me to buy something on the cheap) I still think it is electrical but then i would not be asking advise if I had much of a clue so all advise will be welcome.Thanks.coop Quote Link to comment Share on other sites More sharing options...
coop Posted December 15, 2009 Author Report Share Posted December 15, 2009 Stork you are a star,got me thinking about the choke and with a little oiling of the plunger we are almost there.(did'nt stop me having to push the bugger half a mile up hill on a boggy field though) a little messing and hopefully i will be there.Thank you very much for the push in the right direction mate.Coop Quote Link to comment Share on other sites More sharing options...
stork955 Posted December 15, 2009 Report Share Posted December 15, 2009 Gday Coop, that'd do it - if the choke is not sealing off it would get worse as the bike warms up. Are they a Dellorto? If so, I think they use a needle and rubber seat plunger arrangement - someone will confirm this - it may pay to check the seal is OK too, to make sure it is fully off.
