smelly_cat Posted June 3, 2006 Share Posted June 3, 2006 Hi, my 84 sw with a 1800 carburated engine with a 5 speed keeps stalling. When I look in the float chamber window there is no gas. Then i try restarting the engine for about 3 trys, the float fills up and off i go. Is this a problem anyone else has ever had? The filters are new and the fuel pump is working and the carb was cleaned and rebult with a kit and it runs great. Does the fuel pump shut of while driving for some reason? Some times i can drive all over and no problems, other times i conk out after about 4 miles. Thanks Mike Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 3, 2006 Share Posted June 3, 2006 Float needle and seat are sticking in the closed or partially closed position. I've had that on a couple of Hitachi's. Very annoying. Some rebuild kits are poor quality. Could be a short in the fuel pump circuit or a bad fuel pump control unit too. GD Quote Link to comment Share on other sites More sharing options...
paulpicard Posted June 4, 2006 Share Posted June 4, 2006 AND!!! Be sure you get the various carb vent hoses connected to their respective vacuum-controlled check valves. I can't be more specific, except to say that it took me a year to figure out which went where and cure the intermittent fuel starvation/flooding problems. Maybe someone here has the correct illustrations for this and can post them:confused: Quote Link to comment Share on other sites More sharing options...
smelly_cat Posted June 5, 2006 Author Share Posted June 5, 2006 hey thanks for the advice, I manually worked that stupid float needle and it did not appear to stick but i suspect it. When i had the carb apart I could not get to old float needle valve out so I cleaned it real good and put it back together. Is there a trick to getting a brass float valve out of a pot metal carb top. I was afraid to booger it up any more after the screwdriver wallowed out the top of the the darn thing. . mike Quote Link to comment Share on other sites More sharing options...
