Hi Stu

Have you manually bled tappets before fitting?

I did that when I rebuilt my dg and fitted marco high lift rockers and it started and ran beautifully

Certainly did. Even though new. All bled. Which was probably overkill.
I even test fitted down engine block bore for smooth running. Then placed each in a small sealed container of oil with their respective positions marked on phial.
Too much time on my hands. :rofl

But that was a few months back.

I would do it your way.


Thanks for your reply.
I went to the Internet for answers. Mostly as l have written earlier.
One cut and paste
_______________________________
Procedure
Install the Camshaft.
Set the Valve Lash or Preload as recommended by the manufacturer.
Prime the Oiling System.
Set the Initial Ignition Timing.
For carbureted engines, make sure fuel bowls are full and any air is bled from the fuel lines.
Start the engine and immediately raise rpm to 3,000.
Vary rpm between 1,500 and 3,000 for the next 20-30 minutes.
Use a slow, steady acceleration/deceleration pattern.
Shut down the engine and let it cool.
Drain the oil and change the oil filter.
This removes any metal particles from the break-in process.
Refill the engine with break-in oil.
The initial break-in is now complete. After the next 500 miles of normal driving, change the oil and oil filter again.

Meanwhile, l decided to replace the radiator. The rad cowling was very rusty. So gave it a coating of rust inhibitor. Then sprayed with undercoat. And finally a top coat.

Look at the size of the old radiator. South Africa model?

Cowling cleaned up and sprayed.
