Modded MS880

[Rob D]

Have had my muffler modded on my MS880 for around 3 months now and had no problems. It's louder but not that louder, definately more powerful although I couldn''t say by how much.

 

Starts and runs well but I think now uses a bit more fuel than before.

 

Milling is great especially around the 2 foot mark - you fly through!

 

A guy in the states did the muffler mod - Scott Wojastik. Although it blew out the modded pipe bit after half a tank of fuel (I got it rewelded) the design was good and he refunded me half the money. He hadn't done an 880 muffler before so it was a bit of an experiment.

 

Got to be carefull cross cutting as it can start to singe the bark!

 

Also tried this Oregon square ground chisel skip link chain. It's def faster then normal chain, still smooth and produces less sawdust (so the saw chips must be bigger...). I have 2x 100ft reels of this so if anyone wants to try it it's £.30 + vat a drive link (.404 .063). But I need to get some square chisels from Baileys as can't find any in the UK. This chain is only for soft wood as apparently hard wood will blunt it quickly... but I'll have a go cross cutting some oak later!

cool how much was the muffler rob? does he do them for other saws too? did you have to adjust the carb much?

[Rob D]

It was about £50-00 for the mod I think. But it's the muffler that costs - a new muffler for the 880 is aorund the £180+ vat mark !!!!!!!!!!!!!!! But luckily there was one on US ebay second hand for £60. So I had this sent to Scott and then he sent it on to me.

 

 

He does all mufflers for most saws - I've lost his e-mail address now and also how to spell his name right so you may have to trawl google to find him!

 

 

Another way is get an after market muffler from Baileys sent to him and then he'll post back to you which would probably not be that much.

 

 

I adjusted the high jet to richen the mixture I think it was about a quarter turn maybe not even that. You don't want the saw revving its absolute max but just come off the screw so it has that slight 'chuckle' on high revs.

certainly seems to be flying through the wood! what are you cutting? thought it was oak at first, but reading youre post it must be a soft wood if youre gonna try oak later?

[Rob D]

Monterey pine but it's a good size butt all of 4ft. I've cut the whole of those 2 butts up and it was still pulling nicely through the wood.

That does seem to be very quick!

 

Have you found an increase in fuel consumption with the muffler modification?

[Peter]

It will use a little more juice, that extra power has to come from somewhere, although that is offset by the faster cutting.

[Big J]

I was just curious if there was an overall consumption increase per workload, in the same way that a performance car versus an economy car will use more over a given distance at the same speed......
