Technical Unhappy Engine

[ianhowe]

Hi, new to the forum & hoping I can get some help.
Recently bought a 1970 L which i am told has a 594 126 engine fitted I knew it wasn’t running right when I bought it , It’s really rough on idle like it’s missing .
I have swapped electric fuel pump which I think was defective for a mechanical one, changed carb , plugs, distributor, distributor cap & coil. It takes a long time to start also needed choke .

My car was similar when I got it, but mine was supposed to be working.

First off, you will need choke to start if the engine is cold. That's nothing to worry about. I'd look at the distributor. Is the points gap right and is the timing good? I'm told the condenser can mess things up, though I wouldn't know how to check one.

If it does start, then you're getting fuel and a spark. A weak spark or a badly timed spark would be the first thing I'd check.
