my buddys 02? warrior cuts out as soon as you give it throttle. it stays running, but it missfires and pops through the exhaust. it returns to idle and idles fine. the timing looks ok and we have swapped the carb with no change.its been sitting a while waiting on carrier rebuild, it ran fine before that. any ideas?
Friend of mine picked up an LT80 that needs some work. The manufacture date is 11/1986
The fuel and vacuum lines for the carb were all disconnected. I picked up a new card and was hoping someone on here has a photo or knows how the lines are hooked up
Thanks in advance

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 have a 2004 Yamaha Kodiak, which has taken me to many remote places and hauled lots of game. I still love it after 16 years.
Lately when I go to start it using the starter, sometimes it clicks and kills the power in the display. Lights don't work, nothing works and I end up having to unplug the battery, wait awhile, and replugging the battery ends up giving the power back. Using the winch will sometimes kill the power as well.
Battery is new, all fuses are ok, I'm at a loss. I can start it with the pull crank and it will work and so will the lights.
Any insights or advice would be appreciated!
can anyone help me figure out year and on my grizzly i have no clue rode many of them very first ever owned
