Have a customers 10 HP B&S Generator that hasn't run in years. The carb (like others), varnish up / clog.
The carb body and bowl is both aluminum, two bolts (screw heads) hold the bowl to the body. 5mm (small)
One screw comes loose, the other, seized big time. Hand held impact tool with PB Blaster (while clamped in a vise), no go..
Add heat with a heat gun, no go, just bugger up the steel head of the screw.
Put a vise grip on it, nope, no budging..
Take a Dremel, cut a new slot to the head of the bolt, try the impact tool again, nope..
Now comes the "BIG GUN", (literally). Out come the air Chisel.
*Put the tip of the tool on the newly cut edge. Carefully and slowly, hammer away counter clockwise (not downward) till you see some movement of the bolt . Sure enough, get some movement, hammer the other direction to break away rust/etc. Took a vise grip a full turn CC
before you could turn with a screw driver.
Successfully removed ( I have spare bolts for this reason, threads were fine).
Carb cleaned, machine runs like a top..
