1965 413 This started suddenly after a short joy ride and noticeably gets a little worse each test drive although I think its peaked now Hard to start, and just cant get up past 40 mph. getting to 40 is an effort as well. pressing the accelerator "confidently" up to about 20 mph instantly starts sputtering and bogs down with random thumping and pops. at idol (park) I get a slightly rough idol and intermittent thumping out the exhaust. pulled each wire at the cap and got rougher idol at each one (no help). I looked at the cap and each of the rotor points has a matching "spark scar" that is off center to the same side on each (get that one?) coil plugs and wires with after mkt electronic ignition about 2 years old. Im hoping ignition/timing some how. my buddy says intake (carb) leak. I don't want to hear compression because I just bought a new house...... Thanx again in advance you all have bailed me out heroically in the past. Johan 65 LeBaron Washington DC
