Smells problem
1985 Nissan Truck 4 cyl Two Wheel Drive Manual 123000 miles

have 1985 nissan pick up with carburetor leaking gas on top at air fuel mix solenoid. how tight should screw on top of solenoid be. it has been tightened about a full turn to not quite "wrench tight". leak has stopped but am wondering if that is too tight to where heat may build up cause a failure in whatever seal there is there and cause another leak.
