Hi all,

A bit over a month ago I posted about a chainsaw a Husky 162 I obtained and did a bit of work on (replaced anti-vibes, fuel line and filter) - Husqvarna 162se - new buffers.

The saw starts in no more than two pulls, idles no problem and sounds "normal" (at least to me) with the throttle full open.

Had the chance to cut some hardwood rounds (elm) recently that are about 14 inches in diameter. Cutting is fine if I don't put downward force onto the saw, but if I do, the saw is bogging down.. I would expect a 62cc saw to cut through stuff like this no problem. Chain is sharp and oiled.

Is this considered normal? Could I be seeing a compression and/or tuning issue on this?

Some possibilities: Aggressive chain or green chain? Rakers filed down, too? H mix screw needs tune? Carb screen partially blocked? Slightly low compression that presents under load?
 
It could be a tuning issue. A lean tune will cause this. Wide open out of the wood it should "four stroke, burble, miss fire" and clean up as soon as you touch wood. Madsen's has a good video or audio file you can hear the correct tune. I can hear it better with ear plugs in. A lean tune is also the death of a saw either slow or fast depending on how lean it is.
 
Good advice, thanks to both for you.

I'll start with the tuning (the Madsen's link is very useful) and post back on my results.
