All replies are appreciated thanks people Hi Have you cleaned and checked the carb? sounds like a fuel mixture problem if it runs ok with the choke out. You should also check the autolube settings as this will affect the mixture too. Good luck Geoff Link to comment Share on other sites More sharing options...

yoda Posted August 16, 2007 Share Posted August 16, 2007 Sounds like you have an air leak into the induction system. This is causing the engine to run weak and badley but run fine with the choke open, enriching the fuel ratio. Remove the carb and check all of the seals and mountings for cracks or splits. When re-assembling use a light grease to make the joint seals better. Link to comment Share on other sites More sharing options...
