the spark check was both, checked it this morning, before start up, weak. Yesterday it ran amazing, very response, yes it does have choke, but bogged and died after 10 minutes of idling. Then I'd restart it, it'll run them slowly bog out and die. I used my spark plug tester to check for spark, was getting a very weak spark, when I test the wire straight off the coil, it gets a big orange/ whitish spark. But off the spark plug wire, very faint spark that slowly decipates.
