Trouble Shooting
These solutions aren't necessarily the solutions to your problems, but hopefully they will help you.
Problems I've Had Solutions to my Problems
Carb leaks all the time
-Grit stuck on the float needle. I'm not sure if "float needle" is
the
proper term, but it's the little rubber tipped needle which stops the
flow of gasoline into the carb when the bowls are full. The floats
move the needle up as the level of gasoline rises, but if there is grit
in the way the needle cannot shut off the flow of fuel, and it overflows.
No spark
-Bad condenser, check out the condenser before you replace your
coil. Your coil can be checked if you bring it in to a shop.
-To check your spark plug you can hook it up to a dirtbike,
lawnmower, etc. (which you know works), ground out the threaded
part to any metal on the motor, and turn it over.
If the plug sparks, it's good enough for your motor to run with.
Spark plug gaps don't make a big difference, but it
should be fairly close.
-Bad points. I recently had this problem, I adjusted the points and
after
that it just wouldn't run. I cleaned the points with sandpaper and
carb
cleaner, but it just wouldn't go. My friend Dan really sanded the
points,
and then it ran. It ran like crap, but it ran. I bought new
points, and she
runs like a dream. Bottom line - points are finicky and points are
cheap.
If points are the problem, just buy new ones. Mine were $15 Can.
-Bad wire. These are hard to track down sometimes, but with an ohm
meter it's not too bad. Just hook it up at either end and if there's
continuity, it's good. No continuity, no good.
Runs only with choke on
-No air filter. Mine wouldn't run worth a darn without my air filter.
