For some reason I am not getting NO vacuum at the choke opener or fast idle unloader when I start the engine, I have just fitted a new thermovalve so that eliminates that does anybody no what could be causing this, I would appreciate any help....Thanks
Seems to be an overwhelmingly common problem on our cars, I choke opener may have a hole in the diaphram.. it comes off with screws... purhaps buy a new one fo r40 or repair waht u have with some silocon or something... well i will attemp that but my scres are stripped.Quote:

Try taking the opener off and checking for vacuum at the internal passage where it gets its vacuum.Quote:

#26 goes to a solenoid that leaks vacuum when you crank the ignition... I guess that keeps the choke opener from holding vacuum which in turn keeps the choke closed.
Yes, what you said here is correct. It took me the longest time to understand how the whole system works.Quote:

You can use a paper clip to hold the lever connected to the choke opener so the choke is always open a little, so you dont have cold start-warming up problmes in the morning :-) Thats what I did until I get my weber.
Hose 26 should be the farther one. 18 is the closer one.Quote:
