Explorer 400 Not Starting--Help
I recently purchased a 2001 Polaris Explorer 400, which is a two stroke model. It seems to keep flooding out, because everytime that I pull the plug, it is wet. I put the plug in the boot, and put it against the block, and it appears to have good spark. I pulled the carb, and disassembled/cleaned it, although it looked good.
I found the crankcase drainplug, and removed it, just to make sure that crankcase was not full of gas. It had about 4 or 5 oz. in it, so I am assuming that the float stuck at one time, maybe from sitting.
If I put a fresh plug in it, and pull it over (the elec. start is not working right now), it will backfire sometimes. If I choke it, then it will run for just a second or two, but will only start if I give it just a little throttle.
I checked the reeds, and they look to be in good shape. I pulled the reeds, and looked at the piston/cylinder with a flashlight, and the skirts, ports, etc. all look good. I threw a compression gauge on it, and it was at 125psi.
I could pull it over all day, and it just keeps doing the same thing. Can the timing on a two stroke get out of whack? Maybe a partially sheered flywheel key?
I am wondering if anyone knows the stock carb screw adjustments for the idle and air bleed screws?
I checked the fuel delivery, and there is fuel getting to the carb.
If anyone has some ideas, I would love to hear them, as I am ready to throw a flare into the gas tank. lol
