318 Chrysler V8 problems

Hi bee utey, the engine does make a hissing sound. The distributer doesn't have points.

Furthermore, when the engine warms up the fuel-air mixture goes straight out the exhaust, with the engine just running at about 100revs. When you try to accelerate the engine it pops back thru the intake manifold and pinks and stutters, then the revs gradually slow down until it stops running with no response from the throttle.

When cold, the engine runs well and is very responsive to the throttle, but quickly snapping open the throttle causes it to pop back thru the intake manifold.

Thanks LandyAndy for the locations to spray the CRC Carby cleaner. LRT

Hi Davehoos, this engine only has a manual choke. LRT

If the engine has a mechanical fuel pump the diaphragm may have holed and you may have a sump full of petrol (I've met this more than once!). As it warms up the petrol evaporates more and more and floods the engine. Lift the oil filler cap and sniff for petrol. Look at the dip stick and check for excessive level. You might have to run it on an electric fuel pump instead, after draining the sump and refilling.

Bee utey, I think your right. The rocker cover oil fill smells of only pure oil, but the oil on the dip stick does have a hint of fuel in it.

This engine problem only occurred a few days later after changing the engine oil and filter. Could this be related to the problem?

The carby fitted is a Carter Carburettor, made in USA.

What size or capacity electric fuel pump should we install?

The timing is probably a coincidence. Fuel pumps let go when they feel like it. Simply using the engine more after a service is enough.

As for a replacement pump, I regularly used Facet brand electronic fuel pumps on V8 dual fuel (carby) cars because of the chance of failure of the engine driven pump is too high. Can't remember the correct part numbers but your local auto store should have a catalogue with recommended pump listings.
