Ninety-nine Percent Positive

The other day, as I previously posted, I swapped out Glinda’s modified carburetors for the newly rebuilt ones that were meant for Scarlett. Since that change, she’s been running wonderfully for Mikhaila’s in-town trips. Yesterday morning I couldn’t resist claiming Glinda as my day’s ride. During my brief test drive of a couple weeks back (right after swapping carbs), I could tell that the throttle response was significantly better, but it still a thrill as I headed down the beltway’s on-ramp, transmission in third and pedal to the metal. The tachometer climbed above 4000 rpm with no hesitation and very little needle jiggling. A shift into fourth gear and back to WOT and soon after I was going eighty. What a huge difference. Later that day I pulled into a gas station and put less than seven gallons of high-test into the tank. According to Glinda had averaged over 17 mpg since the carb swap - where she’d been before the swap.

When I got home, I pulled the #1 and #6 plugs and checked them for fouling – nice and clean tip and ground electrode. #1 looked clean all over, while #6 had a little black buildup around the face of the plug body. I didn’t clean them, but put them right back in and will check again after another couple hundred miles. If, after that, the mileage is still good and the plugs are still clean, I’ll be asking the source of the modified carburetors to replace them. I’ll also, at some point, put back the Pertronix Ignitor and coil since they weren’t causing the rough-running.
