posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it? -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb -I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
Hello All, - I have a 1996 Sportsman 400 4x4 2 stroke, and the fuel petcock leaks like crazy. It leaks around the red barrel that rotates to the 3 positions, on off and reserve. Can it be repaired or is replacement the only cure? Thanks in Advance.
