You're right. I have no taste for Pacer chainsaws:msp_biggrin:
I dug out a NOS PS-7300 Orange Top that I had new in a box for a comparison of the three color schemes for this saw.
The New PS-7910
What is SLR?
My understanding of the new muffler is that it's a controlled bleed.
It's using backpressure from the inner chamber to reduce the scavenging losses. This then bleeds into the main body of the muffler.
It'll be interesting to see what differences there are in port timing and port sizing between the new and old jugs too.
You better not let Niko read that the 7910 doesn't weigh more. He was just waving that around in another thread moments ago.
Is there any chance the new coil is unlimited??? Nahh, I didn't think so...that would be too easy!
Well the NEW PS-7910 are selling, and anyone that has bought them or tried them has been HAPPY. As far as NET Weight for Power Head Only as comes in the box here are the results...........
Stock Dry New PS-7900 per our digital UPS Legal scales 14.8 pounds
Stock Dry New PS-7910 per our digital UPS Legal scales 14.8 pounds
Hmmmm same weight, brattier exhaust note, NO CAT, Adjustable Carburator, 15% better on fuel, cleaner running to keep the EPA happy whats not to like??
as far as gross horsepower well I dont have a dyno But in side by side comparison cutting real Logs burring a 24" bar in hardwood 7900 vs 7910 the power and torque are very close!
The EPA Legal saw is still VERY EASY to Service, and do repairs to no major redesign to the saw..., it does have a SLR Muffler, new Cylinder with top side deco, the new lightweight piston same as late model PS-7900's New crank, new coil and a different flywheel. The carb has adjustment screws and a vent hose off the metering pump cover. So again Whats not to Like I ask?????
Both above models are less weight than the CAT equipped PS-6400

That is specs, and according to those the 7910 is heavier, and has .3 kW less power - but specs are specs....:msp_sneaky:
The 7910 specs are 14.7 lbs/6.7 kg and 4.3 kW/5.9 hp - the 7900 specs were about a pound less (6.3 kg) and 4.6 kW/6.3 hp.
It was well known that the weight spec of the 7900 was "optimistic", but it hardly was known that it weighted as much as Scott found.....:msp_confused:
A rev limiter at 12,800 sound really scary, what's the reason for that? :msp_scared:
Btw, my brother is very happy with his 7900 (a new Euro one) so far, except that the potential for porting is somewhat limited.....
Baaaah Humbug!!!!!!!!!!!! That limited coil in and of itself is enough to ruin that claim.
13.6 Pounds Original PS-7900 with Euro Small Spike Bar and no clutch cover
13.8 Pounds Original PS-7900 with large US Spike Bar and no clutch cover
14.6 Pounds Original PS-7900 with US Spike bars and clutch cover
14.8 Pounds Late model PS-7900 with US Spikes and clutch cover with minor changes and upgrades in the saw
14.8 Pounds New PS-7910 with US Spikes and clutch cover
So in real world numbers this saw has gained .2 lbs in the last 10 years.
So the 7900 specs were without the clutch cover - that's quite disturbing.......:msp_confused:
Yes, Yes it is. It is a real challenge to keep the chain tight on these dollys as the tensioner is in the cover, and when the cover isn't on I have to hold the bar out and tight when I cut, and I am running out of fingers!!! Even my friends won't hold the bar when I cut, ya just can't find good help these daze.
