Just thought I'd start a new thread for newbies to the site!
If you're new here, tell us who you are, where you're from and what you ride!!!
Lets get to know each other a little better shall we?
I'm not new to the site, obviously, but...
I'm Kristin from Denver!!! I ride a 2008 Yamaha Rhino. She's my muddy baby!!!!!! Several aftermarket parts on her. She's good to me! We try and ride every weekend. This weekend we're off to MOAB! :woot:

Hi all!
I've got a 1988 LT4WD that I am working on. It sat for almost two decades in a shed, so I replaced both the carb and the fuel pump (Pump was rusty, carb was ok, but had a pin hole in the bowl itself?). Now, I went el cheapo and I replaced BOTH with Chinese aftermarket Carb and Fuel pump. Now is where it gets confusing:
So I did this SAME thing on my other Quad, a 1988 LT300E. They take the same PN carb, and a similar fuel pump, (One has a 90 degree bend in the vacuum port). I've been battling the four wheeler a bit with some electrical issues, but I noticed that at idle it runs GREAT when I gravity feed fuel from a burp can into the fuel bowl of the carb... But as soon as I put it on the fuel pump from the tank, it idles EXTREMELY low and smokes a little. To me, this indicated that the carb itself was running rich. I adjusted it a little on the LT300e, but I could never seem to get it right, it still will slowly die at idle when warm, but ironically if I CHOKE the motor, it'll start up and run. I dont know if this is because the RPM increases? But the quad will run around the yard great at RPM and then die at idle.
Now, the LT4WD. I ended up with a faulty fuel pump for my second (I think the spring isn't seated inside as I can hear one rattling around) so when I installed it it WOULD NOT pump fuel. So I ended up swapping the LT300 pump onto the LT4WD. Boom, pumps fuel. I put it all back together and got my tires on. I ran it around my yard and it exhibits the SAME symptoms as the LT300e! It will run around at RPM, but it will not stay running at idle, it drops realllllly low RPM and will start smoking a little as if its running rich. Again, when I ran it with the fuel pump OFF I didn't have this issue.
In my head I'm thinking it would be a mixture screw OR float issue... But the mixture screw doesn't seem to help me on either, and the bowls are not over flowing (I checked both overflow lines). Is there something I'm missing here thats obvious? Is there a vacuum line or something I missed? Maybe some configuration or something I missed? I reviewed the manual and nothing stood out to me.
Conclusion: Two different Suzuki fourwheelers, two different carbs (Both are chinese Ebay carbs) that BOTH run well when I mainline fuel from a drip can INTO the bowls, BOTH do not keep idle and seem to run extremely rich as they run great at RPM but slowly die at idle. Adjustment screws, idle screws be damned.
I ended up ordering a new Suzuki OEM fuel pump for ~90$ just to have it and see if it makes a difference. Any advice here though would be SUPER appreciated!

Hey all, new member, I just joined here hoping I can find some help, I’m always happy to help others but this time I’m at a complete loss. I’ll try to explain all this as best I can.
I got this 94 220 Bayou doing some trading, the guy said it had quit running, and they couldn’t figure out what was up so he robbed some parts for another one and this one just sat in his shed. So it has not run in years. It was missing the flywheel rotor with the ring gear. I replaced the stator. The factory pickup ohms out to spec, generates ac current (.6 vac), I have an Amazon and a used oem cdi, the original oem smoked when I hooked up the battery, safety relay and starter relay are new. Neutral safety is working. It will crank with the button. But nothing I have done will get this this to excite the coil. I have an oem and Amazon coil. Neither really ohm within the spec but I’m tired of thinking I’ve found the problem and buying another part, so I’ve just been checking for a pulse at the green wire to the coil. I’ve ohmed the wires, checked voltages, used jumpers to get grounds, and I can’t seem to come up with anything. I have been doing electrical troubleshooting for years but this thing has worn my brain out. I cannot figure out what I am missing. Sorry I know this is long winded but I have spent hours with this and am just about at a loss, I’m sure it’ll be simple but I’m at my wits end… thanks in advance

The gas in the tank was bad so I drained it and put new fuel in. It still wouldn't run so I took the carb out and cleaned it. Re-installed the carb and now it will only start and run under full throttle. It also runs rough like this. The engine stops running once I back out to 1/4 throttle. What the heck is going on?
