Hi John.

It was yes.

The conclusion to our issue was using supermarket fuel. It seems the engine just didn’t like it.

Hi RUM4MO

I’m not sure what the cause is. The engine seems to be running fine. There are no misfires.

- running it on the motorway for a good time with premium unleaded fuel
- spark plugs

Any thoughts from your experience ...

I think I’ve found it..
