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!

I can't find a diagram for my Can-Am, all the diagrams have different color coded wires and are missing the necessary parts to fully re-wire my Can-Am. Any help would be appreciated

I have a 1985 Suzuki LT230 GE quadrunner. It has been stored in a shed for at least the last 15 years and has very low mileage. Although the tires look and feel great... should I consider changing them since they are 38 years old? I don't intend to ride to far or too fast but I don't want to have to walk out of the bush. Any input would be welcome.

I just purchased a 2004 Polaris Sportsman 700 EFI. While riding today I noticed the throttle lever
was getting hot, not just warm but too hot to touch. I’ve never encountered a problem like this before.
I have a service annual ordered but it won’t be here for a few days.
Any help would be greatly appreciated.
