Picked up an 046 Magnum yesterday for $220 (at least I think its a Magnum). Its in good condition mechanically and passable condition cosmetically. Saw runs and starts good, has a fresh chain and a good bar. Ive been lurking and learning here on AS for a few weeks. Was originally looking at Husky 372's, then Dolmar 7900's. I thought the price was right, and the power/weight was in the same range that I was looking for, so I couldn't pass it up.
Ive got a couple of questions:
1. I know the "Magnum" is more than just a name, it means 6+hp instead of 5.4hp. Is there any way I can identify it by serial number? It seems too easy to just swap on a Magnum air filter cover. The muffler does have about a 3/4" hole and also a long slit. Is this the 2 port muffler that signifies it being a magnum?
2. It has a 25" Sandvik replaceable tip bar on it with an Oregon chain. Is this a good bar? I assume its ok to mix and match the bar and chain brands, as long as they are the right sizes? I believe it has 3/8" chain, but I don't know anything beyond that (skip, guage, etc). Ive learned a lot about powerheads, but haven't dove into the bar/chain department yet.
3. Pulled it apart a bit last night. Plug and filter are now clean, but I couldn't get the exhaust off to inspect inside. Whats the trick?
4. The lower bolt on the dogs (stock, single, small version) was a coarse thread screw much like those used to hold the handle on. It was a 5/16 head instead of a T27. I assume this is the incorrect bolt, as it was a huge pain to get out, and coarse threads (plastic/wood screw coarse) don't belong in metals. Can anyone confirm or deny this?
5. Ive read about the handle being attached to the gas tank, and dropping the saw causing a tank leak. Has a remedy for this been discovered? What about on the newer models (ms460), and is it retrofittable?
6. In general, what will swap over from the MS460 to the 046? Are they almost identical?
7. When I had it laid over on the fuel/oil cap side, fuel dripped out onto my workbench. Is the tank vent an open line, or should there be some kind of one way valve to prevent this?
8. When I flip the switch to off, it takes anywhere from zero to 15 seconds to cut off. Ive been using an 028av with Electronic quickstop, and it always cuts off very quickly. Is the cutoff delay typical, or something to look into?
9. What is a good fuel mix to run in these?
10. Ive cleaned the air filter and plug and adjusted the chain. What else would be good to do before I put this thing to work?
Thanks in advance.
