CARB ADJUSTMENTS

[ddzylka]

I HAVE A 7.5 FLEETWIN. 1956 MODEL.<br /><br />I HAVE COMPLETED A TUNE UP AND CARB REBUILD, THE MOTOR RUNS GREAT,HOWEVER BOTH NEEDLE VALVES ARE COMPLETLY SEATED, WHEN I MOVE THE VALVES OFF THE SEATED POSITION THE MOTOR RUNS ROUGH.<br /><br />WHY? ANY COMENTS APPRECIATED, OR SHOULD I JUST LEAVE THE NEEDLE VALVES AS IS, CLOSED POSITION

Re: CARB ADJUSTMENTS

I doubt they are in fact fully seated if it runs at all well.<br /><br />They may feel that way due to the packing and nut wearing the shaft "thin" in the area it runs well.<br /><br />If you mean they hit the stops and won't turn anymore, the levers sometimes are set on the shaft with a tapered device that can be loosened and secured, allowing the range to be adjusted.<br /><br />If the packing thing is the cause, replace the packing, and lube it on assembly. If the needle is actually reduced in size in the packing area, you should get a new needle and packing.
