choke rod
Hi Guys,
I need a choke rod and am not sure what to order. The carb is a '73 'vette Quadrajet and the car is a '68 with a stock L79 intake. Should I order a '73 rod or a '68, or are they the same? What I see available from different sources varies.
Thanks!

If you are handy, you can make one from a piece of #9 iron wire. Commonly used for suspended t bar ceilings in office buildings. Should be readily available.
It would be a little harder to make since you don't have one to copy, but not too hard to figure out. Perhaps there are pictures on the internet or in parts catalogs.

You may also have to take into consideration the choke coil. The 1968 coil may turn in the opposite direction of what the 73 Quad requires. Send an email to Lars Grimsrud at v8fastcars@msn.com

Use the coil and the rod for the manifold you are using - not the carb. The rod attach point is the same on all Chevy small block Q-Jet 4MV carbs. The only Q-Jet choke coil that operates backwards is the '68 427. So get all the choke parts for a '68 L79.

Thanks Lars!
Not sure if you saw or not but I think I've found the source of my fuel starvation. Stuck a bunch of clothes pins on the fuel line and it ran almost flawlessly. I never had a starting problem so never really considered a vapor lock issue.
I know what the right solution is (put the return line in) but not what the best alternative is. Do carb spacers really work when fuel is boiling in the line?

No, the spacer will not prevent the vapor lock condition in the line. You need to have constant fuel flow through the line to eliminate the problem - that's why the factory used the return line - it works. Put a fuel return line in it.
