EXCEPT that once it gets up to and has been at operating temperature for a while, it starts to chug at idle and seems to be loading up before it eventually dies, but the plugs show a good mixture.
I've replaced the plugs and wires (original wires) and swapped out the coil to verify it wasn't an ignition problem. I've adjusted the idle mixture and I'm pretty sure I've got it right.
It's got an electric choke and I've verified that the choke butterflies are fully open when warm and I've checked what seems to be an electrically actuated solenoid (anti-diesel?) for proper operation. I'm about to check that the choke cut-out diaprham is OK, but I'm betting it's fine.
It's almost like it's experiencing vaporlock, but I've verified that I've got pleny of fuel pressure at the carb.
I've got and maintain a number of classics (including a Brit w/a Weber DCOE), but this is my first Opel.
The records I received with the car indicate two carb rebuids over the past few years since the engine rebuild (it sat a lot) and I've already ordered a rebuild kit. But unless both prior mechanics screwed up the rebuilds, I don't hold out much hope for that fixing the problem.
Anybody got any clues where I should be looking?
Thanks,
