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
Hi bought a 2012 kingquad ASI last year a great machine which is a delight to ride, but I find sometimes it doesn’t go into top gear just revs high at about 42mph. Any idea ???

Hi guys and thanks for taking the time to read this...
I've took my sons quad apart to tidy it up and replace the carb.
Replaced carb sprayed exhaust etc.. And when I reconnect the battery I get no starter??
I tried charging the battery and replacing it again to no avail.. On the battery ground wire there are two wires that seem to be pressed into the same connector.
I have read about a reset button under the wheel arch but can't seem to get it to work.
Here's a screenshot of the two wires that I think have been fused together circled on a diagram.
Thanks in advance.
Anyone have any thoughts on the early Quad Sports? My very first ATV was a 1985 LT230S, me and a buddy purchased them brand new in 1985, rode those little bikes till the wheels fell off, I would like to find one to restore for nostalgic reasons and to teach my 14 yo son to ride. Nice meeting you all!
