running in new saw?

Some good advice so far and I think this link has been posted before but it's worth reading.

 

Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

 

Now I'm not saying i agree with it, but I've always made sure I get the saw (or any engine for that matter) loaded up from the start. I don't find the biggest wood and lean on it, but I make sure it's doing some real work. Vary the revs too and don't idle it for too long.

I've only owned 2 or 3 "new saws" in my life time but I've rebuilt dozens .

 

My method is to set the fuel mixture slightly rich for several tank fulls at the onset then gradually lean it out .After say half a dozen lean that thing out to proper mixture and flog that thing .Run like you stole is an old red neck Yank saying .Run the knackers off it maybe ,whatever knackers are ?

I see you are from the US and struggling with our old English phrases:lol:

 

Knackers = balls=testicals=kahoonas=dangly bits=rowlocks=ballachs (the spelling is not typical - just swerving the wrath of the good moderators:lol:)

Hmm imagine that .Oh not a big deal we on this side of the pond have so much regional slang stuff it almost takes a translator if those from the midwest converse with the deep south or west coast .Then you throw the Canadians into the mix and it really gets confusing .

 

Then come the Aussies' which I understand perfectly in written text but miss about half of it in real conversation .I sometimes wonder if we all speak the same English which is certainly not the "Queens " English in any form or fashion .

 

Oh not to worry I'll catch on .I just somehow tried to relate knackers to something .My first thought was a well developed busty female but that would be knockers perhaps originating from this side but we'll probabley never know .Enough nonsense .

Oh Knockers, bangers, devils dumplings, titties, boobies, tits, boobs, hooters - there you go, a bit more of the Queens English:thumbup:

I think the main thing to do with a new engine is to not over heat it.

 

 

Dont let it tick over but give it some stick but not for long periods so it doesnt get too hot.

[Al Smith]

A couple things will over heat them .Probabley the worst is tuning the carb too lean .A lean mixure burns faster than a more rich one ,produces more heat .It doesn't help the cause to run a dull chain or crowd the saw too much either .

 

Say little known fact of history on this .In WW2 the RAF and USAF had the escort planes shot up .The Rolls Merlin was a water cooled engine used on Spitfires and later the P-51 Mustang ,leaking coolant they would over heat .Many an old war bird made it back accross the channel by throttling them back and running with the choke partly closed to keep the heat down .

With mine i just put them straight to work. My 200t was dug into a big nasty black poplar takedown on its first outing. Still going strong as to be expected!!
