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

I'm trying to troubleshoot a starting issue. For a while, maybe a year sometimes I would hit the starter button and I'd hear a single loud click, but the starter wouldn't turn. Usually if I could pull the pull start or roll it in gear it would then start. (now I'm thinking that was coincidence) Now it only clicks. I tried to check what I could, battery is good, solenoid clicks strong, cleaned all connections (which were 80% clean anyway). I started thinking the starter wasn't spinning. I pulled it and it spins freely. The gear that it contacts in the engine-I can wiggle it maybe 1/16th to 1/8th inch back and forth. When I reinstall the starter I feel it jerk when I hit the button. I'm thinking maybe it's the starter clutch? It seems when there's a problem with them they usually just spin freely and don't engage at all. Is it possibly something is causing it to lock? I'm a bit lost now.

I need help please. This is all new to myself & my husband. We have gotten 2 used fourwheelers so we can ride with our kids (kids have go carts). One of the 4wheelers is a 1998 Suzuki Quadrunner 500 4x4. It has rearend trouble.
We are having a difficult time finding new or used parts, & no luck with aftermarket parts.
Hoping someone here can help. We were told by Suzuki dealership that some Artic Cat parts will interchange, but he wasnt sure which ones & said there are companies that produce aftermarket parts, but wasn't any help there either.
Any help or information is greatly appreciated.... Thank you.
