Hi everyone, I'm new here.
So the story is I bought my first scooter, a 1997 SK50M, not running. It had been sitting for at least 2 years. I got it home, drained the fuel tank, cleaned the carb, hooked it up to a car battery and tried to get it going. It would almost start, smoke would come out the exhaust but it wouldn't fire and run. Kind of like almost firing, as if out of fuel. The plug would come out wet. I tired this again for a couple of days, then the next day it randomly started right up first try and ran like a clock. No problems at all. I was very happy.
I actually left it idling for an hour and it started right up again as if it never quit.
Then, it wouldn't start a day later. Tested for spark, and it would maybe spark one time and then not again. It has a very weak and very intermittent spark. When I let go of the start button and then try testing for spark again a few minutes later, it would maybe spark a very small amount for a fraction of a second and then stop sparking.
I have unplugged and cleaned all the electrical connectors with contact cleaner. I have the Honda service manual but since I don't own a multimeter (and I don't know how to use it, but an electronics tech friend of mine does, might ask him to take a look but I wanted to see if someone had some good advice here first)
I cut back a bit of the ignition coil lead in case it was corroded. Tried a new spark plug too.
Unsure what else to try.
Thanks
Hessam
