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.
The engine oil dipstick on my 550XP took a dump and the bottom 1/3 was missing. Apparently it's a common occurrence from the bit of reading I've done on it. Anyway I'm not gonna replace it just to have it happen again so I cut the rest of it off and ground it flat to use as a plug.
So now with no dipstick to check oil level I have some choices.
-Buy another dipstick to use as a dipstick...NOT
-Do an oil change and build a depth checker from the new full level
-ask the good people on QuadCrazy! Any one with a like year 550XP wanna measure their dipstick from the base to the end so I can make an oil level check stick?
Want to show you one automotive show that I filmed in my town called Crazy Race. This was two day race in Qualifications round, Semifinals and Final. In this 4 parts I am showing best moments from all rounds and entertainment of the show.
Crazy Race Part 2 contains a qualifying round where all riders race against each other, selected by lot and split by two. They are free to drive in any direction and to hit their opponent's car everywhere except at the driver's door. Anyone who intentionally hit the other car in the driver's door is disqualified. Winner of each race continue in the semifinal round. In this part I will present the best moments of the qualifying round!
Part 3 shows you the best moments from Day 2 - Semifinals and Final. Battles in the semifinals are among the winners of the first day races, but this time they are selected by lot and divided into 4 battles of 4-5 cars each. The rules in each battle are that they only have to drive in one direction and try to neutralize other opponents until there are only two players left. Then the battle between the two last drivers has the rule to drive in any direction until only one who has qualified for the final round is left. Again, anyone who intentionally hit the other car in the driver's door is disqualified.
For the final round there were only two cars left, because the other two players who got the right to be there had problems with their car and could not participate.
Part 4 containing entertainments between battles and winners rewarding.
This event will have second round in 05-06 October 2019 and also will be filmed For this new round I will filmed in many new angels and places. Will prepare a lot more videos and many new entertainments . This 4 videos was my first try so many things to wish for better filming in the future one.
Hope you will like them and of course feel free to comment and to ask everything. Hope you will Subscribe to my channel and to be first to see my other content and of course new round of Crazy Race! Thanks!

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 recently picked up a king quad 700 that doesn't run in the hopes of getting it running by spring. It had been previously taken apart some and a few pieces are missing in the engine, but the frame is complete and in good condition. The motor will need a piston, rings, cylinder, cams, and a few misc parts that are missing. Also the cases will need to be split to remove the pieces of piston that are in the crankcase. The piston blew up at high rpm and did a number on the cylinder so I'm trying to find out if it would be worth rebuilding this motor it buying another engine to swap in. There may be more damage to this engine that I can see so I was wondering how bad the insides of it could be considering it destroyed the piston. I have found a motor for 1200 plus 200 shipping, the only problem is I don't have that much now and I would have to save up a while before being able to afford it. Any suggestions appreciated.
