Husqvarna 2100 thread

It looks like a tiny freeze plug. it tuned like it had a governor though, it four strokes hard, And if I turn of the eight screw and eighth of a turn in but it won’t even rev up it’s too lean

If the governor is working properly it won't run lean. If you lean it out it'll go crazy pig rich.

Thanks. It was timing funny, it was super rich, at one turn, Turing it out to 1 1/2 was about the same, tuned 7/8 out and it would fall on its face before it would even rev up, it was odd. Most saws will at least rev clean turn out it four strokes turn in and it either screams rpm or falls on its face. Just free reving. I did a base gasket delete and now it tunes more like normal.

I should be able to make it there.

That would be cool! I real want to know if my 2100 is running 100%!

You can run lean all the way up to somewhere between 8,500 to 10,500. Can't remember what the the governor is set for. It's tricky because the governor works off of vibration wich was engineered to match a specific rpm via a ball and spring. You can tune your saw as lean as you want under a load ( within reason) but if it never meets that rpm in the cut it will never actuate the governor and fatten up. But as soon as you take the saw out of the cut and unload it and the rpm goes up it will instantly trigger the governor and start running fat as hell and trick you into thinking that you are "ok" on you're tune. If you are trying to tune it unloaded you will have a heck of a time getting it right with the governor functioning .

Looks great. What did you use to polish it?

 

[Bigmac]

I use a 6” flannel buff wheel on a drill press and use blue plastic polish bricks

 

[Drptrch]

Looks great. Link or photo of the brick. Is it a sanding brick ?

These are just some screen shots, they are the products I used but I got them at my local hardware store, it was a ace dealer

Great info.. thank you for posting. Was just thinking last night on how to get the color back in some older plastic.

Some plastic polishes better than others too, I could do a little better prep sanding and it would get a smige better, but I am happy for now, definitely not new looking but much better! And am super happy to get rid of the Bergman!!

What grit did you finish with this time around? I tried the sand and buff deal with compound, but it looked like crap lol.

I finished with wet sand 400, I used and orbital sander to cut the oxidation layer, in stages finishing with 220 then 320-400 wet sand, whatever color you get wet is the color you keep, it dose take some patience, and the buffing wheel takes some time to learn how to use, if you are too aggressive with the buffer it will melt the plastic and leave groves! Then you have to sand them out again! I had to do that on a few spots!

If not perfect it's at least an option. Cutting through the oxidation is the only real way to get the color back. There's plenty of faded stuff around here to practice on..lol

Absolutely! It’s kind of fun and definitely rewarding! Go for it!
