Compression on 372

[Stgcutter]

My husqvarna 372 blows about 145 on compression and is this normal? It's practically a new saw

it's normal

What he said.

I appreciated it. Just wondered why it was so easy to pull since I was using my 288xp. Yes I know the 288 is a quite bit bigger saw but didn't think there would be that much difference between the two

Yes. http://www.arboristsite.com/community/search/678462/?q=372+compression&o=relevance&c[node]=9

I checked my new 365xt tonight, it had 165psi with .035 squish. The saw has only idled a few minutes.

Totally different cylinder. The original 372 was known for lower compression, even on brand new saws. That's just how they are.

This saw is the x-torq I believe it's the strato version I have seen people speak of in other posts

 

[blsnelling]

My apologies Termite.

The X-Torq usually blows a bit more than the older Non-XT models. I wouldn't put much stock in what the gauge says though........how does it run?

 

[Stgcutter]

Runs great actually. It's still on maybe tank 10? I believe the compression has went up since I've had it. All of them around here seem to be that way so I guess it's normal. I really like the saw though.

 

[Mastermind]

Good deal.......I see too many people get hung up on this sort of stuff. Just enjoy your saw.

 

[Stgcutter]

I had thought of looking at my piston. But I believe that I'd have to have a special tool to pull the muffler

 

[Mastermind]

Just a 5mm Allen wrench.

 

[blsnelling]

I think you'll need a 4mm and 5mm.

 

[Stgcutter]

Yeah it's 5mm for the two holding the muffler to the cylinder . 4mm to everything else. I looked at the piston. It looked fine so I'm feeling great now. I run it about 40:1

But thank you Brad and Randy for the help.
