Still running poorly, 914/6... Options

[Lawrence]

It warmed up a little yesterday, so I worked on the /6 when I got home from work.

Replaced two fuel filters, and remounted the pump, that seems to have come a bit loose. I had hoped that replacing fuel filters would clear up the running issue. No luck.

The car runs poorly - under load/acceleration it hiccups, spits, backfires. Once I get it to a cruising speed, it's not too horrible.

The plug wires ore OEM, and only have a couple thousand miles on them. I checked the cap and rotor, and they looked okay. I'll try the new coil from Summit tonight. Any thoughts or suggestions?

Long distance tuning is such a bitch that I almost hate to get involved......oh well.

There are so many things that can be screwed up, but it *sounds* like a side to side carb balance or an idle circuit problem rather than ignition.

On the ignition front, from your discription, your woes can be caused by improper timing or erratic dizzy advance.

I shitcanned points long ago for Pertronics and have never regretted it. They either work or they don't....and mine always have worked.

There are several carb related issues that will cause these running problems....I've experienced most all of them in my Weber learing curve.

I would go back to square one and make absolutely sure the carbs were right. This would include checking the idle jets for FOD.....crud often gets to em' when one has been fooling with the fuel system.
