Sorry Guido, too late, I already pulled the trigger on the Maruyama (metaphorically, I can't pull the literal trigger until it arrives in a week or two ;-)
So, yeah, I bought the Maruyama MCV51 off Amazon today for $330. Here's the answers to the questions I posed above:
-What production year are these saws?
2013
-Is the carburetor adjustable or does this saw have epoxy/cap over the adjustment screws?
No epoxy in the adjustment screw holes, they just take a special tool ("double D bit" or something like that)
-If I needed warranty work, where is my closest warranty service center? (My zip code is 97007)
Pacific Tractor and Implements in Hillsboro (about 20-25 minutes from my house, near work). I called and verified with them too.
-Does it come with a case? [doubt it, but doesn't hurt to ask]
Nope (but according to the parts list, it comes with a Guide Bar Cover)
-Is there someplace online that I can find the user manual (not just a parts list?). I'd like to look through the user manual before buying, if possible.
They emailed me a copy. My initial comparison to the Dolmar PS-5105 manual shows it to be the exact same manual with the minor exceptions of: 1)The warranty page has a slightly different format and slightly different wording in places, and thus takes two pages instead of one, 2)There a slight difference on the parts diagram page, for example, the Maruyama lacks part #23 "Spark Collector, clp." presumably because ALL of the Maruyama saws have a cat, and thus use part #24 "Spark Collector, clp (for models with catalyst)" instead. Likewise, the parts diagram on the Dolmar also shows some "accessories" (that don't come with the chainsaw), while the Maruyama omits those items (e.g. Chain guage, files, techometer, etc)
Interesting little side story, I posted those questions on Amazon last night, and this morning, I thought I'd just call them, so I can hopefully get an answer quicker, make my purchase decision, and hopefully move on with life.
I told the customer service person that answered that I wanted to ask about this chainsaw that's for sale on Amazon and she sent me over to the appropriate person who answered quickly. I started asking my questions, and he said "Oh yeah, I was just answering your questions on Amazon, so I'll just tell you." hehe.
He answered all the questions, and said he'd email me a copy of the manual (which he did), and I asked him if he was sure about the "epoxy in the carb screws questions," and I told him why I was concerned about it (i.e. I live/work between 250 and 580 feet above sea level, but sometimes camp in the Oregon highland desert, which is about 4300 feet above sea level), so could he double check, and also, if it didn't have epoxy, could he let me know what kind of tamper-proofing it had on the carb. He said sure and asked me to hold for a moment, so he could call the tech support guys. When he came back, he said he was just going to pass me over to the support guy to answer directly, so he sent me over to that guy, and we talked about it. He said they didn't put the epoxy on these 2013 production run saws, that they were fully adjustable, but you just needed the special tool, and any of their distributors/resellers should have the tool and be able to adjust it for me if needed.
All the people I talked to there were nice, helpful, not a lot of hold time. Great experience talking with them, so after a couple minutes of sitting there working on actual work (my job), I thought "Why haven't I ordered this already," so I did.
Thanks for the suggestion Grack.
