bogging

Here’s the video of what the saws are doing. It started after I took the oil pump off to look for worn parts due to a small leak. The clutch was on a little tight so I had to throw some starter cord in the cylinder to keep it from spinning and ended up breaking the clutch and getting it off. I...

What brings me here is my pesky tricky annoying saw, the Stihl MS (yep) 250. What a joy. It runs an hour perfectly. Then bogs and says "I'm tired". It likes to take breaks when I want to work and vise versa. Troubleshooting this saw is like a further insult. You do everything known to man to...

Hello all! I'm hoping someone with good experience with MKI and MKII T540 XP Autotune Husqvarna's could possibly give me some advice. I'm working with two T540 XP saws one is a MkI other is a MkII. The Mk I would run fairly normally without load and for the first 5 minutes it would run in the...

only about 50% of the time. The rpms will drop and the motor sounds like it's trying to sort a bad idle. This can also be caused if I take an ambitious bite or sweep on an angle in to the stump. High idle doesn't recover until I've either disengaged the head and rolled the dice again on...

Hi, as you may have seen on other threads I've posted today, I've bought a MS211 as a non starter for next to nothing. Managed to win the first battle and got life into it after some tinkering. Next issue is the ungodly bogging I'm getting. Anything over 10% throttle and it sounds horrible...

This thing is killing me. I have a Stihl MS170. Recently it started bogging down when I would put any pressure on it. The carb was replaced. Still does it. If I get the chain up to speed and put it on the wood, it cuts nicely... until I put any pressure on it. There is also smoke coming from...

Hey guys/gals first off wanted to say I really enjoy this site and there's a lot of helpful stuff on here. Ok, I just picked up a Mcculloch pro mac 10 10 chainsaw from the 70s from a lady whos dad owned the saw and passed away. One owner saw in great condition cosmetically and mechanically it...
