Re: Need help to set idle
Update time. The main source of the problem is a sticky and leaking throttle shaft. Complications were a small leak in the inlet manifold. No vacuum to the distributor, and numerous small faults in the carb itself. I'm just organising for a replacement base now. I found it by accidentally jamming the throttle butterflies completely closed and all of a sudden the vacuum jumped up to 20" and the idle mixture adjustments started working properly. In the meantime I also have a new inlet manifold gasket, nicely painted inlet manifold, replacement V belt of the correct length this time, and a nice new shiny vacuum feed line to the dizzy. Thanks to everyone for your guidance. Not a hope I would have got there without the support from the people on the forum. Pictures of the offending article attached.
PS: Anyone know the thread size on the small vacuum port on the manifold riser?
