Hello.
I've got a problem that has stumped me. The symptoms are:
Engine starts and runs fine. Pulls great in all gears with loads of power.
As soon as i get on a Motorway and get up to above 55mph for more than 30 seconds it starts to die and splutter. it also backfires.
It returns to normal after it slows down to about 40mph (not fun on the Motorway!)
I thought it must be a fuel issue, so i have changed the fuel filters and pump. I also changed the coil leads and plugs. It is already running an electronic ignition conversion.
I've checked the vacuum advance pipe and sucked on it and the distributer does advance.
i've cleaned as much of the carb as I dare take apart. So just the float jet and the excelerator plunger (which was sticking).
It's all made no difference at all.
Any help would really be appreciated!
Thanks in Advance.
Paula
