Exhaust Question

[ChevLoRay]

You said Pungent, but I think Acrid may be a better term.

Before I changed my carb, and later my distributor, being around my exhaust gas would bring tears to your eyes....and they weren't happy tears. When I bought my truck, it had an Edelbrock 1405...jetted for performance. Mileage was terrible and the truck ran rich...which caused the acrid, eye-burning odor.

So, I changed to an Edlebrock 1901 (Q-jet). The engine ran so much leaner and hotter that I had to put a heat shield on the starter solenoid. This one item got rid of that eye-watering smell.

I had also had a problem with plugs that became gas-fouled. It was better with the new carb but changing the HEI out ,for an Accel reman unit, really stopped the problem with the plugs.

But, I think your carb is running too rich, and that is why you complained.
