"If the screws are siezed use

"If the screws are siezed use a Dremel w/a cutoff blade to cut around each cap screw tab leaving the screws w/tab intact. Make a crosscut in the tab next to each screw w/o touching the screw. Remove the cap and carefully remove the tabs around each screw w/a small chisel and hammer w/o breaking off the screws.

Next saturate the area top and bottom around the screws w/PB Blaster to help dissolve the corrosion. Wait a few hours and GENTLY TRY to turn each screw back/forth w/a large screwdriver. Repeat process as needed to remove screws. Use a locking pliers if needed. If a screw breaks off, file it flush, center punch it and carefully drill it out and tap it."

"One of those micro butane torches works very well, too. Just be careful with the carb and the fuel vapor hazard."
