Husqvarna 525LS is Kinda Boggy 

Thanks for watching!

Thanks for watching!

Thanks for tuning in!

Thanks!

Are you referring to the tight spark plug? I suppose I could have hit it harder but I have enough tools I shouldn't have to hit it at all!

@@TheGreasyShopRag. Approx 5:17 into the video. Odd you are richening , and just last week I had leaf blowers needing a tweak mainly to help start.

@@steveriggenbach90 I see screws so I turn them 🙂

The term "four stroking" is used to describe a rich condition at full throttle. You can adjust a carb so the engine runs perfectly smooth at full throttle but if you richen it up just a little more it will eventually run so rich that the tone changes. It almost sounds like it misses a beat...kinda like a four stroke engine that only fires every other stroke. I should point out that you can pick up on this same rich condition at idle once you know what you're listening for.

Thanks so much@@TheGreasyShopRag

Can't argue with that...mostly because I don't know what it means.

Thanks for watching!

Thats possible but I don't think so. It could have had a lean tune even for hot weather and when it got cold outside that tune would have been even leaner. I've also seen where units sit a while and the fuel starts to gum in the hi and low passages. Fiddling with the adjustments gets things full flowing again. I know that seems weird but I've seen it many times.

I am also thinking about what changed that made it run too lean. Leak, clogged exhaust, owner messing with it, other ...

Yes an air leak can cause a bog but an air leak would have created a high idle which we didn't have.

@@rooster3019 I knew someone was gonna ask because good running units don't usually just all of the sudden need a carb adjustment...unless there is an elevation or temperature change. I think that might have been a factor here because I saw a lot of lean runnings saws recently as well. This trimmer could have been lean the whole time and our cold snap was just too much.

@@TheGreasyShopRag That is a good tip for me about barometric pressure since I tend to work more on bluebird days.

@@TheGreasyShopRag I was asking in regards to a husky 141 I'm working on. Replaced piston and cylinder, fuel line and filter, rebuilt carburator, new impulse and and intake boot. Starts up, idles but wont rev just bogs.

I hope it can help you in the future. Thanks for watching!
