Got a bit of time to day to iook at it again,so I found. 

It would run at full revs assembled back together, popped rocker cover off and tappets were out of setting reset them. 

Tried it again no luck, so while it was running popped breather pipe from rocker cover to airbox off and smoke like a coal fire, and engine ran better and ran flat out with no spluttering. 

So I am thinking rings gone. 

 

Just to clarify, the smoke was coming from the breather and not the exhaust?

If the breather, I would agree, time to pull the top end apart and check the piston, bore and rings.

Yes from breather on rocker cover, bought it second hand a year or two ago and is 8 years old in total. So I have decided to put new engine on it as got no idea of history, will probably pull head off and look at condition of it. Got a shock when I message Unipower and they said could not get Honda engine till April.

OK, fit a new one, Locin are fine and Predator seem to be good on the Youtube tests but not sure if they are USA only then the Honda can be a nice little bench project for the winter.

Loncin are very good for money.  Sounds like you've sorted but I could help you with a new engine if you need

Yup, I run a Rover Mower and chipper both with the Locin engine, seems OK to me.
