I strapped mine to a pallet.
Ran on tick over with a little revs every few seconds for 3 tanks.
Takes a while...
Then milling small diameter 12-24" logs for a few tanks.
Then into the big stuff ever since.
Big difference from about 15-20 tanks. Torque is epic.
But at first I was disappointed by lowish power. It builds.

I like everything you're saying, but just thinking back to my 2-stroke bike days. We used to do something similar, setting the revs for a thankful. I remember some people suggesting the engi e could develop a flat spot running the engine at the same revs for a prolonged period

Hi Con fuck I totaly remember that as from my 2 stroke days , so anyway fouled it up this afternoon when the bloody rain stopped, and free handed a small walnut chog I had kicking around in the yard , totaly chuffed ace new saw , after the year I had last year good way to start this one , now I need 4 ft bar and chain , as I got a call today to go and Mill 2 , oak butts 3 ft wide and 10 ft long , it will be tough on my ankle but hey got to get on 

Thanks for all your comments  Mark

My ha'penny's worth , would be 3/4 throttle fr first tankful, an wear stripey socks just in case. K

I have to respectfully disagree Khriss .  Saws are designed to run at idle or flat out not in between for any length of time . Just use it normally from day one . The socks are fine though

What does the manual say? I'd go with that. 

 

I've never seen any manual suggesting running a saw on tick over for any extended time. Sounds like something the bloke down the pub might suggest. People should be cynical about where they take their advice from.

Ah, the old "run in" question.....

When the piston, ring and bore are made, they aren't all quite perfectly round and they also have rough machined edges - not that rough but rough enough.

These rough edges, if moved against each other for a long period produce excessive heat which is bad for a two stroke. The answer is to move them against each other for a shorter period of time but flat out.

The reason to use a saw flat out for short periods of time when new or a new top end has fitted is that these rough surfaces don't stay rough for long so you have a small window of opportunity where all the parts rub against each other and wear to each others shape until they all fit each other perfectly.

If the parts wear quickly to shape, you get better compression and a better running engine.

The worst thing you can do is to take it easy as the parts will lose their rough surfaces and the engine will glaze over and never seal as it should!

I have to fill 2/3rds of the way through with my 088! 

Yeah, but only when the chain is blunt,
