Oil & Fuel b2400 fuel cut off solenoid

[d1king]

Can not believe asking this type question, but here goes. No. 1 fuse, 5 amp blowing when starting, substitute 10 amp and blow within 1-2 minutes. Checked wiring, no short in harness. Ordered fuel cut off solenoid, started trying to get old one off, no luck. 10 mm seems to small, 11 mm seems to large. Has anyone ever changed one of these and what size socket did you get on it??

Figured it out. Takes a 10 mm thin wall (very thin) deep well socket to reach in and get it turned. Mowing again.
