    I would check the fuel tank next. The fuel filter might be blocked or the vent line or fuel lines might be kinked.

    As I was at a pawn shop today, I ran into an older fellow that has this same exact chainsaw, and, brought it in to put a new carb on it. He was unsure of what to do and I told him I do small engine repair and he sent me to work. The carb kit came with an intake boot, and, little did I know what I was getting into with that. He wanted the new lines and intake boot and all installed, so I took it home and will take it to my shop tomorrow. I would suggest inspecting that intake boot, but (spoiler alert) you will need to remove the entire engine to do so from the main plastics. I got down to the clutch assembly, which, once removed, you can then remove the engine. Hope this helps!! Love your videos!!

    I had a similar problem with my chainsaw. It turnout that the fuel line had a crack but it was in in tank just below the grommet. The carb was sucking in air and fuel

      @@HomeGaragechannel Rule #1 is always start at the beginning. Never assume that someone else’s previous repair was done correctly. That can have you chasing your tail for quite some time. A tiny nick, split, or a loose fuel line can give you fits. Replace the fuel filter and lines and don’t look back. Just because a part is new doesn’t mean it’s good.

    I'd change the plug to what it calls for, NGK BPMR7A, not use HIPA plugs. Change the fuel line and filter. Get an OEM carburetor as THAT model uses a cheap carburetor. Stihl sells them for around $20. But, honestly, I think it's the plug being bad. I've run into that quite a bit honestly. If changing everything doesn't work, then it needs a new coil which isn't cheap for the OEM Walbro coil it needs.
    The MS170-180 use duckbills as vents in the oil and fuel tanks FYI.

  • @dah61789dah
    @dah61789dah Год назад +3

    Considering all the junk in the carb I'd be looking for a clogged or broken fuel line and filter. Also check the tank for crud and the vent tube.

  • @johnclarke6647
    @johnclarke6647 Год назад +1

    You can remove the periscope from the original carb and put it on the new carb. I have done it lots of times. My guess is tank vent. However you can adjust the Stihl carb, but you will need a very small torx bit or jewelers screwdriver. There are very small torx bit holes in the adjustment holes, which you can adjust like most other saws. I have a brand new ms 170that I found to me turning over 14,000 RPMs. I backed out the high jet a quarter of a turn and dropped it down to a respectable and safe 13,030 RPMs. I had to use the smallest jewelers screwdriver that I have. It must be a #1 or #2 torx bit slot in the adjustment hole.

    Sounds like lean running so either carb or a vacuum leak. Non-adjustable carbs are a BIG no no to me but that's what we have to put up with a lot. I'll get an adjustable if I can find one if I'm keeping the machine. If not, it might go on down the road. I don't have enough hair left to leave it on a rock because of banging my head on it trying to figure something out that can't be manipulated. The 261 has instructions on how to readjust the carb if it gets off kilter BUT it's commercial grade and not entry level. Battery stuff would be their way to go. BLESSINGS

  • @mrtennessee6862

    Always replace the fuel filter, there cheap. Check for leaks from the carb. Never buy a cheap aftermarket, unless you have to of course. You can also pull the fuel filter and check for leaks that way also.

  • @aaronpowell4885
    @aaronpowell4885 Год назад

    Seems to me like if the fuel filter is clean and line is good, it's getting unmetered air from somewhere. Crankshaft seals, case seals or intake maby? After saying that, is the metering lever set too low? Also worth trying it with the fuel cap loose to eliminate the possibility of a bad vent.
    Thanks for sharing👍🏻 look forward to hearing what the issue ended up being!

    Its sucking air. Either the intake boot, cylinder gasket, or crankshaft seals might be letting air in. Take the top cover off, have some carb cleaner or WD40 or whatever, start it and spray around the intake boot. If it doesn't change the way it runs, it'll probably die out. Start it again and spray around the intake gasket. The seals don't really go bad unless its old. I want to say its the carb because I saw a small brass jet in there. I'd hate it to be rubbish under those oblong welch plugs. If it's not sucking air, I'd go straight for the jet. Make sure your rocker arm is flush with the carb body (diaphragm mount).
