Ok, engine went really rough, all cylinders were going. I changed the electronic distributor for an old points set but its the same as before. Checked compression: 165 to 170 throughout.

Not sure what to try next?

OK, new known working distributor and it idles okay but when it runs its like I'm tapping the accelerator. Very jerky!

If you are SURE about the compressions - and haven't mixed up the plug lead order in all the excitement....then you will need to look further to ignition or carb problems. Maybe it's the coil....... :oops:

Start on timing first. Also valve gaps. Adjust carb later but best to err on the side of rich.
