<VV> Fuel Issue

[Bryan Blackwell]

Hi Steven,

I'd say it's likely one of the following:

 - Gunked carbs
 - Fuel line clogged/air leak
 - Not a fuel problem at all

My suggestion is to try to isolate which area it is.  The car should run for a few seconds on a good shot of starting fluid.  That would eliminate the last possibility.  My money is on some gunk in the carbs, those passages are really small so it doesn't take much, some fuel may have dried out and then running the engine knocked it loose.  I've had some success with just a good blast of carb cleaner down the vent holes and idle cluster holes.  If that doesn't work, if you can get a helper, is to remove a fuel line and attach a hose directed to a catch container and have someone crank the engine.  You should get a pretty good amount of fuel (there's a spec in the book).  You could also rig a line from the fuel pump inlet to a gas can and see if it runs off the can.  From there you can work through the carbs or lines, depending on the result.

I should note that the tank was replaced with a new one from Clark's about 10 years ago.  There aren't many miles on the new tank.
