here's another one for you guys, I thank you all for the help. great board.<br /><br />2000 25 hp johnson electric start, ran fine last night 12 gals. worth and then this morning won't start unless I prime the heck out of it, then it won't run long enough to let go of the primer. If I keep priming I can keep it running for maybe 10 seconds or so, then it won't start til I prime the gas line bulb ( which is staying hard, I even tried other tanks, and lines--same thing) and prime the heck out of it again.<br /><br />any ideas? this baffles me since it came out of the blue.

If you ran bad gas the carb. might need to be cleaned. It has happened to my 30hp

EAW....are the gas line connectors clipped on all the way? If you can, slip a dish or jar under the carbs and remove the bowl drain plug. Check the gas for contamination.
