Good Morning All!,
After a significant amount of reading and tinkering, I'm stumped. We have a pair of Arctic Cat DVX 90s (4-stroke), and one of them runs very rich at wide open throttle. I've cleaned the carb (which was installed new last year), verified the main jet (80) to be per the original spec, installed a new air filter, tried a hotter spark plug (CR6HSA), and adjusted the valves (tightened a modest 0.0005" but improved starting). The hotter spark plug may have help just a bit, but not appreciably.
Just for fun, I swapped the CDI between machines, and that didn't help either.
Fouling plugs very quickly, but not to the point the machine will not run or start. [black instantly]
Logically, I assume I'm revving out, but the other machine doesn't "stumble/blubber" anything like this one.
Should I try a smaller main jet?
Any ideas you guys may have would be much appreciated.
Thanks in advance everyone.
Have a 2005 grizzly 660. Just recently started backfiring and showing incorrect speed. Lifted seat and messed with wire going to starter relay, it stops for a bit but seems to come back.
I ended up pulling all the pins out of the connector for the relay and added new pin/connectors for all 4 wires. fixed it for a little bit but came back shortly after. This was a new starter relay i installed a few months ago. Anyone know if a bad starter relay would do this?
I'm outfitting my middle aged '02 Taurus with a new starter and need some advice on what brand starter to get. I'm tempted to get this reman Motorcraft, the fourth one down in the orange remanufactured section.
For $123 that seems reasonable for a OE reman. If not this one I'll probably be going for a reman of another brand so why not go OE?
The other reman options I'm seeing at the car stores are...

Should I go with the Motorcraft or one of these? $123 sounds almost too good although I really don't know.

My 2005 Kawasaki Prarie 700 will not go over 27mph, seems to have low to no throttle response, dies out whenever you don't keep the throttle up, seems to have no power, and the 4x4/2x4 light keeps flashing back and fourth and also there's a red light on that I'm not sure what it means, any help would be greatly appreciated
