I'm having a misfiring problem and don't mess with engines directly. Well, usually. My Speedster motor is all Gene Berg, 2005 cc, with the addition of CB 9:1 heads, 42mm Berg Webers, merged headers, 009 distributor with an MSD energy unit. One cylinder has been popping for several years, both at sea level and the 6500 ft altitude in Colorado. I took the car to some very meticulous performance guys in Glenwood Springs, CO. The problem seems to be on the lower end, decelerating and at low speeds. These guys thought it was the #2 cylinder, played with the Webers to no avail, thought there might be some internal gunk. However, I later removed rt. side carb, disassembled and it didn't look bad. No improvement. They also felt there could be an ignition problem and suggested an MSD distributor. I ordered the distributor but haven't installed yet. Any thoughts here? The car performs okay when you put your foot in it, maybe getting a little warm on the highway which makes me think the mains might be a little larger in spite of being the same as at lower altitude. Plug readings are okay but went and black on the right side tail pipe. There might be some room for change in the idle jets. can't provide the size but I did reduce those before the car went to CO.So, any experience with the MSD? These units have extra springs that allow the advance to be tuned as necessary.
Thanks,
Dick
