I have a New In Box Dolmar 7900 and was wondering if there is any special advice you guys have for firing it up the first time.

Should it be adjusted fairly close from the factory, or will it run lean/rich, etc... ?
 
Dump fuel mix in it, and bar oil, and go cut wood.

At least that is what I do... Oh wait I have never bought a new saw in a box... my dealer has always gassed them up, tuned them, and cut some wood before I leave the shop.

But then again... my dealer spoils the hell out of me.

I'll admit it...

I'm a Stihl guy having a Dolmar moment. I bought my father a Dolmar a few weeks ago off ebay and it runs like a banshee. Then I decided he can't have all the fun himself so I bought myself one NIB a week or so later. No Dolmar dealer near here. It's the one I need a bar for.

I figured those Husky guys out there might have some suggestions. No pun intended:)
 
Follow the instructions in the little book that Dolmar wrote that accompanies the saw. You probably don't want to cowboy it for the first few hours. Check and make sure everything is nice and tight and you know how the controls work, how to start and stop the engine and the chain. Get some safety equipment if you don't already have some. Lastly, if you are new to felling, etc. get some instructions from a persion with some experience in this. You can badly hurt yourself if you don't do it properly.

Without a tach is isn't easy to mess with the tuning so I'd stick with the factory tuning. If it is missing when it has been run for 10 minutes you might attempt to smooth it out. It is probably best to let the pros at the dealer do it for you though. My saw is tuned slighty to the rich side. I think that is so if my air filter gets clogged the saw doesn't lean out and damage itself.

Get some good engine oil, blade oil, and some spare parts, plug, filters, chain, scrench, etc.

Being from Big Sky country you probably know all about this stuff.

I would never run a new saw without taching it just to be sure. Even if it got tached once before, once it is hot it may rev higher. Or on your local gas.

And especially for the first tank or two all my saws started reving a little freer/faster. So I like to set them at 3 to 5 hundred revs low until things settle out.

I'm a Husky guy and I buy them at my local dealer. Just as GASoline71's dealer, my dealer sets it up, runs it and go's over it with me. They also stock all the parts I'll need and will service my saw(s) and trimmer as well! :cheers:
 
I still don't have a tach. I have mostly modded or full race saws so there is no standard rpm to guess your fuel ratio with. The true test is reading the plug, brown is good and grey is bad, or even better an egt which will measure the fuel ratio through the burned exhaust gas. Tach settings are just a close guess at best. 7900's like a good burble just a touch on the rich side.
When I break them in I like to tune them just about as rich as I can while still sounding good in the wood, at least for a few tanks.
