	alright i have a 1994 polaris xlt 580. its only running on two cylinders. the closest one the the clutch is not firing it has spark and its getting gas. it was leaking coolant from the head cover so i replaced the gasket and the o-rings around the spark plug. i just did a compression test and it has 85 then when running has 125. would any one have any idea what could be going on?

	make sure you of course have a good plug. switch the plugs with another cylinder, make sure you cap and wire is good. 2002 Zr 500 CCE D&D pipe ported polished y 6 inch riser Acerbis Handguards Chrome winshield Pro-glider Rack Rsi pad Ripped graphics Fox snow pro shocks clickers Rating: 0 Quick Edit Full Edit

	bad crank seal? start it up and spray either carb cleaner or ether around it and see if it fires on that ,spray around the cranksaft behind the pto pulley mid Il alway's waiting for snow,moving north(way north)2001 thundercat 99xcr 800 97SPX ULTRA 96 zrt 600&800,92 doo plusX 92 v max 4 750 Rating: 0 Quick Edit Full Edit

	85 psi compression is too low . you have a problem in that cylinder . Do another compression test this time on all three cylinders and compare the readings to each other Rating: 0 Quick Edit Full Edit

	Quote originally posted by mrholmquist 85 psi compression is too low . you have a problem in that cylinder . Do another compression test this time on all three cylinders and compare the readings to each other i checked all the cylinders there all 80psi when i pull the rope with the off switch off.when i put the two spark plugs in and check the pressure of the one cylinder it has 125psi. then once its running i can pull the spark plug wire off the cylinder it stays running as if i didnt do anything to it. i pull the other wire off the other ones and it wants to die.

It could be the spark plug insulator. Rating: 0 Quick Edit Full Edit

	so if you install the other two plugs and check the compression the pressure goes up??? That doesent make sense unless the head gasket is leaking between the cylinders?? Rating: 0 Quick Edit Full Edit
