Problem starting Race Spec Pinto

[rlk500]

Guys, I have a Race Spec Pinto engine in my '78 RS2000. It runs on twin 48 DCOE's and hasn't been started for about 10 years.....I have a spark but do not appear to be getting any petrol into the engine. It's getting to the carbs but no further. All the jets have been cleaned and the float chambers are filling, but the juice doesn't get to the combustion chambers, the plugs are as dry as a bone, yet the car will fire if I spray easystart into the chambers.

Firstly any carb guru's know what could be stopping the juice getting through, secondly if I take the carbs and manifold off, and operated the throttles with the fuel pump on, would I see a small build of fuel in the manifold, thereby indicating that the petrol was at least making it as far as the manifold.

TIA

Have you cleaned all the jets/emulsion tubes out with CARB cleaner?
The old petrol will have evaporated off and left a sticky varnish/residue that can clog them and prevent fuel from flowing where it should.
Also, is the pump giving good pressure, 3 to 7 psi should be right for a mechanically driven pump.
hth.

I noticed some of the varnish'y stuff in the jets and emulsion tubes. I think I will re-do them all again just to be double sure.

What's the best method to test the pressure from the pump. It's a remote external (in the boot), so is easy to access.

if theres fuel in the carbs pump the throttle the acceleration jets should spray heaps in

I'll second what turbospud said, hold the throttle open with your finger and look down the trumpets, you should see fuel dripping into the carb, if not you know where the blockage is if the floats are filling up.

Didnt realise it was an electric pump. Your fuel pressure may be somewhat higher in that case, depends upon the pump.
Go for the cleanout first tho of the jets.

Thanks guys, I'll have a fiddle.
