Ive been having problems with the carb lately.
George Fraser did a bit of setting up, i.e timing was out so that was set, then he tried to set the CO, but kept jumping around, eventually got it set at 2.5, but didnt seem right when i started driving, was really holding back, and the next morning, took a while to start.
Then i tried a primitve method to adjust the CO, i.e setting it to the point the engine revved most. Worked well, now like runs nicely when warmed up, but still very hesitant untill it reaches full operating temp.
Idle, by the way, is perfect now, must have been timing.
Anyone guess why im only having problems when cold??? I have set the autochoke up perfectly now (i think), starts at around 1300rpm when cold and goes down slowly...not as perfect as modern autochokes, but at least it does something now!
Unless anyone advises otherwise, i am going to buy a repair kit and rebuild with new needle, jet, o-rings etc. Never done before, but armed with my Brooklands manual and some stuff i found on the web...
Any insight much appreciated.
