Help Me! loss of spark

[mako1990]

i have a 2000 ox66. i have noticed power loss when riding sometimes comes and goes. changed all filters primer bulb spark plugs, while checking spark realized one cylinder spark just goes out after like ten seconds from starting, if i gas the throttle hard it comes back but then goes out again. changed the coil and still does the same thing. please help me!!

Have you checked the plug wires? Sometimes the clamps holding the wires in place could ground out a bad wire. IMHO

Re: Help Me! loss of spark

can you post a model number?
some OX66 engines drop cylinders at certain RPMs by design.
dont chase ghosts.
did you clean the vapor seperator filter ?
the one inside that metal tank on the port side of the engine.
