i'd check the carb out along with the crank seals...and the fuel line and filter.
those 42's had a nasty bend in the fuel line. i "fix'em by blocking the original fuel line hole in fuel tank off and drilling a new hole in the fuel tank,so as to give the new line a more straight shot to carb without that nasty bend in it.
can supply pic if needed.

the screw is put in the "old" fuel line and is used for a block-off.you can see the "new" hole i drilled for new fuel line and it's new position,with no kink in it.
