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

A friend of mine has this particular 4 wheeler. It sat in the garage for about a year, so I redid the carb, cleaned the tank and installed a new petcock. So far, it cranks right away whether its button started or pull started. So I have a couple of questions concerning the carb and air filter.
1. Is this a cvk32 250 or 350 carb? As the air fuel ratio adjustment is different according to a cvk document I read. What's your adjustment setting? 2 whole turns and a 1/8 or 2 whole turns and a 1/2? Comparing the old setting on the carb to the new setting (and where the needle sits now), makes me think it was way off before.
2. The Air filter cover, gasket, air filter and plate element are all missing. So I was thinking of removing the hose that goes to the air box and put one of those K&N style looking filters and be done with it. So my question is.. will I have to readjust Air Fuel screw or just adjust Idle?
It's just going to be driven around the neighborhood.
Thanks in advance for any info or help. Y'all stay safe out there!

I know a lot of people say not to use anything but Oem. For the sake of the those who chose not to, or the OEM part cost more than the project, lets hold back negative comments.
I just purchased a carburetor that is supposed to be up to OEM specs. The company has a good reputation on eBay and Amazon. The Carb is supposed to be for this bike and jetted exactly.
This question should basically go under carb adjustment. I installed the new carb, the bike idles fine. On throttle it sputters half the time and the other half it will rev up fine. Does this sound like the needle is set at the wrong point? Does it sound like the main jet is the wrong size? Or is there another adjustment besides the air/fuel screw thats is 2 turns out?
Yes i could truck through old threads and possibly find the answer, but i thought it would be nice to have one tailored to new carb installs.

Has anybody on here installed a winch on a 2003 Magnum 2x4? I am using a Cycle Country adapter plate (only one I could find), but am having a bit of trouble getting it all to fit properly, and am looking for someone that may have done this install and/or may have some pics of the installation.
Putting in a SW Terra 35 and I've decided the crimp I'm looking at here isn't something I can reproduce so I need to figure out who to take this wire to get the end put back on after I get it shortened to where I need it. Never having delt with wires this big I have no idea who I could go to just locally to get this done. What kind of (electrical?) business would deal with stuff like this?
