Engine sputtering...

Re: UPDATE: Engine sputtering...

Hi Wana, Take a look at the spark plugs after the next good run they may tell you something.---Keoke

Well, I've finally gotten time to go through the suggested items. I replaced the fuel filter, checked the fuel pump flow into a milk jug, replaced my Flamethrower Coil with the old stock coil and finally took the Pertronix out and put the points back in. The car still runs exactly the same - sputters a bit when I accelerate. So, I'm now wondering if it could be something with the carbs? As you may recall, this condition started suddenly, while ideling waiting for my son at the pool. The car had been running perfectly for 2 years, and as I pulled away from the pool parking lot I noticed the sputtering for the 1st time. And it now does it every time I drive it. It starts fine and seems to idle fine.

Any suggestions on what to check on the carbs (or anything else that might come to mind)?

Thanks! Wana

Wana,
You may wanna give this a try. With the engine significantly sputtering, turn off the ignition key and pop the tops off the carb fuel bowls and see how much fuel is in the bowls. Very little fuel means fuel delivery problem. Blow out all the fuel lines yet? A pump can have good static pressure and still have substandard fuel delivery.

Just a thaught to add into the mix, had a similar problem with my BJ7 some time back, ran upto 60 - 70 MPH then backfiring and so on, could not accelerate any more. This was finally attributed to the fact that only one carb was operating. They are HS6s and the fuel connection from the bowl to the jet was blocked on one of them. The good side was great fuel consumption, the bad side was lack of anything above 60 - 70 and that the engine must have been running lean, meaning a very hot burn which may have contributed to the ultimate demise of an exhaust valve.

Give your carbs a check over
