So it WAS a 7300 that I made a 7900, but the bar oil weeps out of that thing like it was designed to. I found a couple of old threads that say I should replace the oil lines with green ones--are they still available? And from who/where? Also, I'm trying to remove the clutch to access the oil...

I need an OEM cylinder & piston for a Dolmar 7300. Would consider used if in very good condition. Yes, I know it can be converted to a 7900, but I have a 7900 and don't need another. PM me if you have anything, or let me know if you know where such a thing is available. It's a ps7300 if it...

Saw starts & runs great for about a 1/4 tank, then dies--doesn't stumble, just dies. Early on I suspected a hot fail of ignition coil, as it seemed to show no spark in this condition. And it didn't want to restart until cool. Replaced coil with new OEM. Saw still dies after running for few...

On my chipper there's a connection where one section of exhaust pipe has a slight leak. It wouldn't concern me except that it's a male section above and female below, allowing rain and snow melt to funnel down in. Don't want any moisture to get into the turbocharger or worse yet a cylinder...

Make an offer. I need to move this saw. Selling this Stihl 041AV one-owner saw from our fire dept. Probably was little used (but I can’t guarantee that), as our saws mostly just ride around on trucks. Our mechanic rebuilt the carb, and the saw starts on first pull. 135 PSI compression, but...

Got a scored ms260 pro. Need to replace slug & jug. I'm looking at the cyl and need to know how to determine if it's 44mm or 44.7. Above the Mahle name it says W2 and 44zk3. Other side says Stihl 1121. Enough to go on?

I just rebuilt a 371--new top end and crank seals. It's running like a sewing machine, maybe a little too well. I seem to remember 371/372 should top out at 13,500. I've got this one about 13,400, but it sounds too smooth, no burble at WOT. Is 13,400 a safe top rpm, or should I be hearing...

To begin with, a full trigger pull would only begin to open the throttle--too short of its intended distance. The trigger assembly felt wonky. So now I have tank removed from saw, and trigger parts removed from tank. (It looks like a challenge to figure how the spring, the trigger and the...

The PTO crank seal on my 346 fails on pressure test. But I'm confused. Threads I've seen here say that seal is integral to the bearing, meaning I'll have to split the case and replace the bearing. Somewhere else it mentions a seal # 503 26 22-01 that would do on its own. What do I need to...

I've got a 2005 346xp that leaks fuel thru the tank vent. I've searched threads and not found anything to help me. I pulled the tank off the saw thinking the fuel line might be the culprit, but it's good. Put fuel in the tank it drips out the tank vent. What's it like to replace one of...

I bought this 346 as a non-runner, put a new p&c in it, and new crank seals and carb (OEM). It’s just now about broke in—8 or ten tanks of fuel thru it. Been working up around 8,000’ elevation, which I thought maybe accounted for the weird tuning issues. But yesterday it was running like dog...

Since the gauges were shot on my ’97 Woodchuck 12” chipper, I bought a new Murphy control panel and wiring harness. It was advertised as “plug and play,” but yesterday when I picked it up from the mechanic he said I’d need to calibrate the tach, something that left him scratching his head...

On a 1,180-acre county park/preserve (Betasso Preserve) across the fence from my home, a fire-mitigation-thinning operation in Ponderosa Pine woods is nearing completion. It’s a $1.3 million heli-logging show creating fuel breaks on three areas totaling 189 acres, through 50—80% fuel reduction...

I was helping on a volunteer fire mitigation project yesterday, cutting in a mixed stand of lodgepole pine, Doug Fir, and aspen at about 8,000’ elevation (Nederland, CO). We remove the trees marked by a county forester, and swampers haul the wood and slash to the roadside. As this is my day...

The nut securing the flywheel to the crank in my 371 spun off and the woodruff key got demolished. The key slot in the crank is clean, but the part of the key in the flywheel is stuck tight--the inner dia. of the flywheel looks like a smooth bore (although I can see the key). Is there a way to...

The ID plate on my chipper is gone, but it’s a Woodchuck WC-12 drum chipper, 1997?, with a Deutz 4 cylinder diesel, oil-cooled setup. I could use the control panel—start-key switch, tach, temp gauge, oil pressure, and so on—and the wiring harness behind it. If someone has a similar machine and...

I need trailer brake shoes for my Woodchuck WC/12 chipper. The ID plate for the chipper is gone, so I don't know what year machine this is. The outflow tube for the chips is round, unlike the square-tube models you usually see, if that means anything. The machine is powered by a Deutz diesel...

I need to replace the flexible tube from the blower to the outflow chute on my chuck and duck Woodchuck WC/12. I could give big $ to Altec for it, but surely this tubing is commonly used on other equipment. Can anyone give me name, specs, and/or a source?

A good chunk of my work the last few months has been a dwarf mistletoe removal project in a 20 acre (30? I forget) stand of ponderosa pine. If a tree is fully infested, it goes. (I climb and trim whichever ones can be saved.) While I fell a significant number of trees, I like to keep a dead...

I picked up a 371xp recently. Cleaned & put a kit in the carb, & replaced fuel line & filter. (Walbro carb 21-477) It runs fine, cuts well, but doesn’t like to idle. With the idle screw backed out entirely, it’s still turning the chain at a good clip. The end of the mixture screws looked...
