Hi folks. My brothe-in-law's EH 149 exhibits this cursed problem. He's had the car for about 10 years and was doing it on the drive home back them. The car runs very well otherwise, under load up hill, full throttle acceleration is great. After about an hour it begins to surge at whatever cruising speed you're doing at about half throttle. Floor it and it goes real good, back off and it slow down smooth but hold throttle to cruise at constant speed and it begins to buck. Items recently replaced with new include plugs, points, condenser, leads, coil, dizzy cap. Ign timing set, float level checked, full tank of fuel, new fuel pump, ballast resistor bypassed. Vacuum and mechanical (rpm) advance are working. Sure, it’s either spark or fuel but what exactlyis the cause? Vapourisation was a possibility but because it accelerates up hill perfectly, it ain't that. TIA Freddy Edited by user Sunday, 20 October 2024 6:52:25 PM(UTC)
