Walbro SDC-1 Fights Me...Welch Plug Removal Was Necessary! 

I really appreciate this video I recently got an old craftsman 3.7 chainsaw that has this SDC Wal bro carb and I’ve been trying to get it running for days , mine is very odd though as it has no H adjustment knob there’s just a plug in that spot so more to dig into to try to get her working with the help of this very informative video, thank you

Great tutorial, thanks for sharing. Would be a good video to show how you cleared that Welch plug hole on another video.

Good video Leon. Shows what working on this stuff is really like.

Thank you so much, I watched one of your videos explaining the low speed circuit and I was thinking that was the only thing I wasn't able to check, after watching this video I think I feel more comfortable if I have to open up the welch plugs and inspect those circuits, sorry about the spider, lol

They can be tuff !! Great job on that one.

So far I've been blessed , not having to deal with Welch plugs. I've gotten quite a few saws running well without it.
