Husky 50 Special Mod?

[maplemeister]

I have a Husky 50 special that I purchased in May of 1992 and am wondering if this is a saw that would benefit from a Muffler Mod, and if so, has anyone done this same model in the past or not. Saw has only seen light use over the years and still runs great. I started selling firewood this past fall and this saw is going to be my main limbing saw for a while so I wouldn't mind beefing it up a tad if it makes sense. It will be seeing a lot more use from here forward so a faster cut would be a timesaver. Can anyone advise?

Thanks,

That should be a non epa one,if it has a fully adjustable carb(high,low and idle) I would go for it,should see increase in power and throttle response.I have not done one of those but have done my Husky 44 and I can notice the difference.

How much did you open it up. I was thinking of just drilling holes in the face of the existing muffler but not sure how big they should be or, how many Any
thoughts on that issue?

Alot of AS members say to go 85% of your exhaust port size(that is the hole that the exhaust comes out of the cylinder at)and some say 75% to 125%.I would go 85% adjust your high speed on the carb and see how it runs,you can always go bigger.I did what you are talking about on my 44,just drilled a hole.I will be welding the hole shut and welding on a pipe in a couple weeks.Heres a pic of the 44 hole in the muffler and a pic of the exhaust port on my 026.You can use some spaghetti noodles and fill the exhaust port with them to get a measurement for the size,you will have to take off the muffler to do it.Your hole should be 85% of the volume of the noodles or close.Hope this helps,I'am no expert but I am learning.You can also do a search on the site for muffler mods which there is alot.

The 85% is a total of your stock muffler opening and your new hole.

Ok Woody:

Thanks for the tips. I never would have thought of the spaghetti approach unless you mentioned it first. I will figure out the opening I need and just go with a drilled opening for now. If that seems to work ok, I can always weld an exit pipe on later. I don't have any welding skills to speak of but can get some help with that part if needed. Again, thanks for the assistance.
