Not a sidekick, just like minded, sane, and I can think of 4 or 5 AS members that had 5100S blow up and not get covered. Stop making excuses, cold hard facts are making you look a little silly. Nice fanboy attitude by the way. :monkey:

Also, not bashing Dolmar, they make some really nice reliable saws, history has told us the 5100S is not one of them.

Well grasshopper if truth be known, and yes I do know it, there have been a awfull lot of Huskies fry as well. I bet I see at least 20-30 a year and its not the saws fault just like the 5100. Most of these saws I see come from TSC, Sears and Lowes. They aren't set up at time of sale, they are delivered to the customer in a box and out the door they go. Some are running too fast, some are sold to idiots that don't need a saw at all. Even so these saws sold at dealers that are frying pre maturely is usually the fault of the dealer not checking the rpms levels and some of it is the customer himself. Dull chains will fry a saw, hell alot of things will fry a saw. I've seen alot of Stihls fried too but thank goodness they weren't the ones I let out the door, they were bought elsewhere.

A dozen 5100's fried on this board tis no biggie in the overall pic of things. I will say this board does seem to help get the Dolmar name out more so than Husky or Stihl. That said when one frys the bad news tends comes back to this board.

Not strato, but has a cat muffler.
It's not clear yet, (not enough info) but I think it has the same engine as the PS-5100, and possibly the same 14.500 rpm coil.

Awwwwwwww ok. Welp that muffler will clean it up. Thats one of the ways to get rid of the emissions, burn em up. I hope that muffler didn't gain a ounce, Sawtroll will raise hell,:laugh::laugh::laugh::laugh:

Ethanol info

Good info. What stands out is they do not say ethonal is the boogie man behind every engine failure, good on Dolmar. Dealers should not tell customers well its the new ethonal laced fuels that runied your engine. Any that do is just asking for trouble for the customer will do his homework and come back fit to be tied.

From fuel bulletin:
Lean carburetor settings and high operating rpm’s can create potentially
hotter engine temperatures!

From PS-5105 bulletin:

Improved air flow system for better engine cooling.

So the PS-5105 has a catalyst (which would potentially allow Dolmar to richen the mixture? plus better cooling.

Sorry if I came across that way. I probably did. I'm simply trying to make it clear that the root cause is the tuning, not the fuel. Of course, proper tuning does vary based on the fuel being used.

:cheers:......Lost in translation I guess.....I was just trying to tell the gentleman how to test the fuel himself, for his own piece of mind and future reference for anyone else that wants to find a station with good gas.

I was not trying to insinuate that's what caused his saw to seize. We regulars here pretty much all know what's causing these 5100s to seize and that was already covered so......

I hope that muffler didn't gain a ounce, Sawtroll will raise hell,:laugh::laugh::laugh::laugh:

Well after 5 pages of posts, back to the OP's original post. Your warranty is 2 years so it should be covered. I was at my dealer a while back and he had a 510 sitting there that a guy had straight gassed and the dealer didn't want to even turn it in (mostly because the guy was a jerk :) ) but Dolmar covered it so you should be more than fine.

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...

Not a brand war but can you honestly name any other saw has had as many lean failures as the venerable 5100S? You certainly don't hear about 346XP, MS260 or even 7900 saws blowing up with low hours obn them, especially by the dozen. Might be something else to this, design flaw or something not even related to fuel mixture.

I bought 2 346NE from local dealer both blown from bad gas .....The dealer was the same one that would not sell a non cat muffler for them ......I bought both saws with out original P/C ....He gave me new P/C in boxes along with the deal .......Dealer sold me the saws and gave owner 2 new ones .......

Bad gas will kill any saw!!!.....Huskys are not immune....

Woodshed That's 4 Huskys now to 1 Dolmar just recently, sure must be something wrong with those Huskys. Steve
