Raw power would be a big bore 2 stroke on 2 wheels. That’ll make your sticker peck out!

Thanks for the help. This thing is going to be used for doing stuff around the property. No joy riding. LOL I have my fun on 2 wheels. The wife likes the quad riding. She has a Honda rancher that we bought new in 07.

Yup. Performed the tests and ruled out both ignition and relay switches. Turns out the problem was in the on/off switch. The old thing runs pretty good!

If I ground the green wire on the solenoid side of the plug and put 12v to the white wire that should engage the starter right?

Ok I have a solenoid and ignition switch on the way. The owner said he started it at one point with the key. When I got it, turning the key did nothing. No dash lights, nothing. If I turned the key on jumper the solenoid it would crank over.

So the white wire, coming from the ignition switch, when I turn the key to start, should energize? Or if I put power and ground the green wire that completes the circuit and the starter should engage? I’m thinking that the ignition switch might be the problem.

Ok that makes sense. I’m guessing the green would be the ground?

The one I need to replace has a 2 wire plug coming out of it. Searching eBay I see tons of them with only 1 wire . WTH???

Come on man!!!! LOL I mean after the flood of gasoline I plugged the stuff up and all seems good. I appreciate the feedback and the help. My experience with these types have been if they leak replace it. I never looked into how they work. So now I understand a bit. Still don’t understand the thinking behind using these type of prtcocks.

Again it’s not the needle/seat/float. Needle and seat are brand new, OEM, and the float is set at 13mm. And like I said, when hooked up to the auxiliary tank, zero issues. Here’s what I found yesterday. Yikes! That’s mostly gas, just from the engine. The bike holds 2 quarts of oil and I think I drained probably 3.5 quarts total out of it. So apparently at some point with the fuel tank connected it was leaking into the vacuum port on the carb. Cuz that is a lot of gas in the oil. I must have left the petcock in the PRI or RES position overnight or all day long or something. As I posted earlier the thing died on me and after seeing all of the gas in the oil I was kinda freaked out thinking that I ruined the motor somehow. I put some fresh oil in it and it fired right up and everything seems cool. I do have a new petcock on the way that doesn’t use the vacuum port.

That’s what I’m thinking of doing. I don’t see the reason behind the vacuum operating the petcock like that. Gravity always works. Anyway I got the thing back together plugged the vacuum line and capped the port on the carb. Went for a little ride, 2-3 minutes, and it was crapping out at WOT in 3rd gear. Then it just died. Couldn’t get it to start again. Checked the plug, it was wet. Spark is good, compression is good. I pulled the filter to look inside the intake and I see a bunch of oil in the airbox and in the carb. Is it possible that when the engine got flooded with gas that some seeped past the rings and into the crankcase? It happened 2 times, but I pulled the plug out and pumped the fuel out both times within about 15 minutes or so. The dipstick shows over full and it smells like gas. I’m assuming that nothing was damaged with the short ride time?

Well as I explained in the OP, with the auxiliary tank hooked up to the carb the bike runs great, zero issues.

Thank you for the explanation. My gawd, I haven’t been on here is several years, the freaking ads are off the chart! Anyway, so pic 1 is the ON position, and both fuel inlets are covered. So that’s where the vacuum comes in? I don’t see how it gets fuel, but it works somehow, obviously. The 2 pic is the PRI position and it opens up the reserve port. And pic 3 is the RES position and it opens up both ports but no fuel would into the carb supply? Couldn’t that vacuum be bypassed and would just have to treat the PRI position as ON and it would be drawing fuel, via gravity, but in effect you would have no reserve? I just looked up a $10 petcock and it only had ON/OFF/RES, so it looks like it deletes that vacuum thing.

I rebuilt the carb on said machine. When I hook up the auxiliary gas tank it runs fine and everything is cool. When I put the fuel tank on and hooked up the lines, it completely flooded the cylinder and even about an inch of fuel in the air box. I'm pretty sure that it comes from the little hose on the petcock and hooks to the top of the carb. WTH is that even for? I mean the thing runs fine on the auxiliary tank, so idk And on the petcock when it's in the "on" position, I get no fuel. The petcock from the bike I took it apart and checked out how it operates. The sharpie marks indicate how it really works. Now the other petcock w/o the sharpie marks is an old one that was leaking that I removed from a Polaris quad. It's exactly the same thing, except the small hose and nipple have been removed. I'm so confused, LOL

Ya, 90 bux for a t-stat! I remember when I was a youngin my Chevy trucks took a $5 t-stat.
