  • Alternative seized bolt removal procedure!

    I have a customers 10 HP B&S generator which hasn't run in years.

    Carb typically varnishes up with gunk. The float bowl (bowl and carb body are both aluminum) is held on with two M5 bolts.

    One comes out easy, the other no so mush (typical on these engines).

    Carb clamped in a vise, hand held impact tool, nope, just damages the head. PB blaster, heat gun and impact-nope... Add vise grips, nope..

    Dremel out the head for a "re-newed" slot.

    Now the big gun (and this is a first for me), an AIR CHISEL. With the new notch, the carb not going anywhere, I used the sharp edge of the chisel
    to catch one edge of the new slot. Position the tool and chisel to hammer the screw CC, not down.

    Go slow, back and forth some, just like an air gun on a tight lug nut..

    Took a full turn before it would come out without the vise grip once broke loose...

    (I had spare bolts as this IS usual for these engines as I generally replace them with allan head bolts and anti-seize).
