PMD1969:
I have a QJet that has not run right in years.  At the moment I just need to limp it along until I can order Cliff's parts and rebuild it.

The symptoms are that the choke is not working.  I recently replaced the choke thermostat and that is working.  The carb adn choke are all original and the carb was rebuilt in 1995.  What is happening is that the primary flap stays closed unless I manually work the carb by hand.  I had temporary solved the problem by removing the primary flap but that keeps the secondaries from opening.

I can provide a picture if necessary.

Looking forward to getting this fixed to so that this OHC will finally wake up and run.

Appreciate the help.

What is the part # on the carb? Is it a hot air, electric or divorced(on manifold) choke?

I'm not familiar with tweaking the divorced choke setups. The carb-mounted choke could be adjusted too tight, or the thermostat could have been installed backwards so that it starts open and closes as it warms up.(may apply to divorced chokes as well).

It's a pretty simple mechanism, really.

7029261  I am sure that it is simple for someone with experience but I have never really worked on it.  The divorce choke is good.  I know that the choke mechanism is way out but I have no idea how to adjust it?  I may put the primary flap back in, disconnect the choke and just resolve to flooring it when its cold.

I meant no disrespect when I said it was simple - that was in reference to the on-carb choke. In the case of the divorced choke... I'm clueless. :)
