2100 husqvarna

[Oldfeller]

Ok, understood, the fuel leak is right on the seam, and as you are aware the 2100 cannot be split and simply reassembled with gaskets like many other saws, I did some investigating and it appears many have tried numerous ways to cure leaking fuel tanks, using a sealer seemed to be the most common and effective method, next to swapping out for a 480 tank and losing the manual oiler.

in my case the oiler seems to be working fine with no transfer of fuel to oil or vice versa, would this indicate the existing plunger seal was intact?

If you are not getting transfer between tanks then all is fine, you may, or may not believe this but I have sealed tanks and holes in tanks, use the very runny super glue, run a bead along the seam, now liberally sprinkle bi carbonate of soda over it, within minutes it will set like concrete, if necessary rub down and re apply, don’t knock this till you try it.
