Busted my phillips head trying to loosen the two screws that hold the Run-Off-Start switch to the handlebar. Suckers won’t budge. Tried WD40, tapping the top of the screwdriver with a hammer, cussing. There’s no room to grab the pan head with a vice grip. If I use a torch will it melt any plastic inside? Ideas?
Using a hammer and a flat ended punch, hammer straight onto the head of the screw, peening over the surface until it is deformed, then using a 3/8 drive screwdriver bit, hammer it into the deformed head, then install an impact driver into the 3/8 screwdriver bit, apply counterclockwise pressure while hitting the impact driver with the hammer.
This works every time, been doing this for a long time and this is a successful procedure.
Got ’em out! Spent the $14 to get the Irwin(r) Screw-Grip(TM) Impact Extractor. One bit with two ends. First end is a drill. You drill out the top of the screw pretty deep. Then turn the bit over and it has a gouge that digs into the hole you just made, its teeth grip into the metal walls and since it has reverse threads you keep the force going on your electric drill and it backs out the screw. Of course, you have to replace the screw…
