I need some troubleshooting advice, guys. I have been doing my fall maintenance over the last couple of weekends including a semi-annual removal and cleaning of the webers as I had noticed a increasing roughness over the last couple of months. Since then the car seems to run on about 3 1/2 cylinders - 3 good and one not completely out of it but not healthy. My first thought or course is clogged idle jet, but after a couple of removals and thorough cleanings I am not so sure, nor do I really want to remove them again. Could it be that the old adage or "Most carburetor problems are ignition problems" be true? What is the best way to diagnose? I will try the old "remove one plug wire at a time" trick, but I would like to hear other suggestions. This seems like a more regular misfire that usual from a clogged idle jet and it seems to happen at all RPMs.
Today was the first Saturday in several weeks where the weather was good enough to drive the Speedster to Cars and Coffee and I was pissed that I couldn't.
Also - I need to buy some spare idle jets for the carbs (.060s) and wonder where the best place is to get them.
