Question for you guys. I have a 98 bayou 220 that I picked up cheap cause it's wasn't running. So it's has very low compression. It is getting spark and fuel.
What should my next course of action be? Any other tests I should perform or where to start looking?
Thanks in advance.

I picked up a 2000 Big Bear 400 4X4 that was sitting around that I know nothing about. It will not start. I do have a red light when in reverse. When I take it out of reverse, I do not get a green neutral light, and when I push the start button the red oil light comes on but there are no noises, nothing else happens. How do I test the neutral switch and/or bypass it to see if I can get it to at least crank? And does anyone have other suggestions for me to try?

I did a compression test on my 2005 Bombardier Traxter 650 CVT and it's 75 PSI. service manual only talks about leak down test. No specification for engine compression the manual. What does 75 PSI tell me? Thank in advance.
A little history of this machine. 640 miles. Picked it up about 2 years ago, not running. Probably the computer. Tested all circuits and confirm it was the computer. Long story short, I watched a Youtube video and fixed the computer. ATV now started and runs. BUT, it tops out 20 MPH. I cleaned the carb 3 times also using a Mikuni carb kit after the second time. Slide in carb is going up and down. Only adjustment for fuel is at 1.5 turns out. NGK Sparkplug had soot on main part but brown on the electrode. Champion sparkplug is brown. I check CVT clutches and they both appear to engage like they suppose to. Checked valve clearance it's 0.00, I can't get any feeler gauges in-between. I check timing chain I believe it's in the correct position and hasn't skipped. I removed muffler plug and drilled into muffler to try and make sure it wasn't plugged.

Hi!
I got my KLF300 running again with your help a couple of months ago, at that time it was the ignition coil that had failed. It has been in use since then without issues until two weeks ago.
When the new issue showed I was going at about 10km/h and it suddenly slowed to a halt. I started it again after that with choke and I drove it 400 meters and parked. Next time it was really hard to start, and since it was low on gas I thought that was the problem. It didn't get any better with a full tank, so I assumed it was the cold weather, and adjusted the pilot slightly.
After that it I actually got it started again with full choke and some slight gas, I drove about 300 meters and then it slowed down to a halt again. After that, it hasn't started again.
The compression is 165psi. The spark has good intensity, the ATV has functioned before with the same spark "intensity"/light. I *assume* that it has gas as well, there is definitely gas on the spark plug when I remove it
I have checked the carburetor slightly, the float works, diaphragm looks ok, but I haven't disassembled it to really look for dust and such in all the small places.
My theory right now is that it might've been some dust in the gas tank that went into the system, it's just a theory
I'm thankful for all the help and pointers I can get, don't hesitate
