Powermax fuel starve

Recommended Posts

My 4040 runs till the bowl emptys. Original float was cracked, so replaced and set height. Sometimes it will run an hour, sometimes 30 seconds. Is the fuel pickup in the tank filtered? I have a new clear inline filter and needle and seat apear to be working. Maybe fuel pump is bad. If I crank engine with gas line off, it pumps fine. Maybe I will convert to electric. Any ideas?

my wager: seat sticking or float hinge hardware sticking. it's where you were working and not much else it could be with fuel flowing happy when hose is pulled. but I've been wrong before. I'd pull the bowl and put a fairly clean bit of fuel hose on the carb, blow gently and play with the bowl (also gently). it should shut off and open promptly and without any hang ups. at this point if no problem found you put it back together, and maybe it works fine rest of its little metal life.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
