I'm looking for some help getting my '78 puch newport back up and running. My wife was out riding it when it died unexpectedly. I can't get it back up and running nor for the life of me can I figure out what the issue is. She said she was at partial throttle riding downhill when the engine "revved for a moment then died".
Here are some things I've checked:
-Fuel flow to the carb (15 bing) is there (brand new fuel as well),
-Jet is clean,
-Air filter is new this year, doesn't seem like that would cause this problem anyway,
-Big fat blue spark is there,
-Compression pushes my thumb off spark plug hole with ease, and
-I wouldn't expect it to be an exhaust problem as I replaced the whole pipe earlier this season.
When I try to start it, I am getting very little if any ignition in the cylinder.
Any thoughts on what would cause such a problem with the above conditions?
Thank you for you help!
