EPA...sounds like just another case of the Gov't. screwing things up. Sorry to hear about your 5100 burning up, I'd definately push very hard on getting it replaced or new P&C for nothing!
Woodshed That's 4 Huskys now to 1 Dolmar just recently, sure must be something wrong with those Huskys. Steve
Big whip .....I have easily a 120 tanks plus through my 5100 these last 3 years and have yet to burn it up so come up with something else to impress us.....Like some proof of "several dozen" that you know about. Not a handful on a AS that you heard about.
Hey Tommy, I wasn't very clear but by better cooling I was refering to the other major change on the PS-5105, an "improved air flow system", not the catalytic muffler.I don't know about cooling but yes it would allow the motor to be richened up some, lowering those rpm's. That cat muffler is nothing more than a afterburner. It will burn up the emissions as they exit the engine lowering over all emissions numbers. The bad part about a cat muffler is they get extremely hot which is how it works. They tend to choke performace somewhat too. Alot of saws have them and have no issues with them. They are a cost effective way to lower emissions without having to redesign the whole unit.
Stihl used them on some of their smaller saws a long while back. I think they still use them on their FS55/45/46 trimmers, I know they did, I haven't looked in awhile. They also had them on some of their blowers for awhile. Stihl has made it clear they don't want to burn off the emissions in the muffler, they want the emissions burnt up during combustion before it reaches the muffler. Thats why they're going strato. Strato nets the same clean results as the cat muffler but without that hot afterburner in front of the engine, fuel being more completely burnt in the cylinder netting better (less) fuel consumption as well.
Its only a matter of time before the fuel injector comes along for small handheld power equipment along with new cylinder designs to go with it. When that happens and becomes the norm the EPA problem will be resolved for good. Course EPA will turn around and make us buy tags for our equipment and make us get our saw emission tested once a year, sounds funny doesn't it, don't under estimate those sorry ba-stards...

Well if you count the 372 sitting on my bench and the 261 and a 41 and the three 395 I sold in the last year (sorry urbicide) your on the list for the next one I get ....
Well that list can go on with all the brands ........

I'm with everyone that thinks the carb is not adjusted correct. I can't see a company like dolmar/makita putting a saw on the market that they know is going to fail, if their trying to break into the market share this would only end up biting them in the ass in the long run.
So with the new saw have they actually improved the air filtration?
Enough said for me. Here you go Fast, here ya go Ultra
Dolmar Bar is open!!!
These saws wouldn't have any problems if it wasn't for the EPA and ethonal both a crock of sh...... . Steve
