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

Hi, think water got into the tank, have managed to drain fuel (not the best experience) and empty the carb of fuel ........ so it starts now and runs however, it cuts out on fuel and won’t restart, it will restart on reserve ? When I turn it off and back onto fuel, it will start again. If I take for a short run on fuel it will cut out again and only restart on reserve 😳. Any ideas what else I can check. Many thanks
Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎
My Dad's 03 Manual Vinson has milky oil. He changed oil and ran it everyday for a week being sure to keep it running for an hour each time. Fresh oil is getting milky again..
Thinking it's the water pump seal. Has anyone here successfully changed the seal or even replaced the whole pump assembly?

Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00. It's been sitting outside with no carburetor on it for about a year. Its rusty, missing some parts, wiring is all cut up and spliced etc. No seat, no racks but the plastic is all there minus the headlight housing. Anyway, who can pass up a $40.00 quad right? I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water. I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine. I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark. Did a quick compression test, 70 lbs. Wet test bumped it up to 90. Ok, so rings and cylinder washed out with water for a year, not too surprised. I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show it's got life. Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either. The compression is now around 60.
Anyway, my question is....is it worth it to try to get this thing going? I tore the top end down today and the cam and one of the rockers is pretty worn. I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well. Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again. Much less just to make it run and use as-is but I won't really like it until it's right. I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much. I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down? I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
I'll get some pictures today if anyone want to see them.
