Default Misfiring 350 GP

I've been going through the newly acquired 76GP , and I can't figure out the missing.
The previous owner stated that it would miss on start up and then clear up. I did drive it 500 miles it had no power .
Now it pops and backfires, and no clearing up.

I have new spark plugs and leeds.
The timing is OK as I put a timing light to check it but I may need some advice on doing it properly.

The distributor cap and electronic ignition are new from the previous owner.

It will backfire through the carb and pops out the exhaust.

I know it's a *****ie 350 with a possible 120hp.
I will need to replace it in the future but for now I just want to get it driving.

The carbie is new and is made in China with no brand name.
It still has the big catalytic converter in place.
At one stage on the drive home, the engine had a loud ticking noise which did go away.

Do you suggest I remove tappet covers and have a look what might be going on and do a compression test next?
