My 94 200 still runs rich at low rpms and loads up, but does not die. My hole shots take a few seconds to get going after the engine finally clears out from loading up.<br />I have:<br />replaced bad thermostats (one stuck open)<br />checked compression--all good<br />checked for leaking or high float levels<br />synched/linked carbs<br />set timing to specs<br />replaced one bad coil<br />replaced all 6 recirculation check valves(3 bad ones) <br />checked all hoses and check valves(except for valve in crankcase housing)<br />checked primer operation<br />35/42 low and mid air bleed jets ok<br />air bleed screws seem best at about 4-7/8 turns out<br />all sparkplugs are correct and clean<br />All of these things have helped slightly, but the engine still runs rough and loads up at low rpms. Is there anything else that anyone can recommend? <br />SGC
