I have a kasea mighty mite 50 and it ran fine untill the other day it just shut off and will not crank anyone have any suggestions

 

If you have gas, is your plug fowled or wet? Does it have spark? Pull the spark plug and ground it with the bike turned on. Don't touch anything metal and turn over the motor. If it shocks the hell out of you, you touched the plug and you probably got spark. But look for spark in the end of a new plug. If you have spark do you have gas getting to the carb? Pull the hose off the carb, does gas run out?

If no spark use a multi tester and see if you have any AC voltage (around 120) coming off the magneto. If so do you have any (I Believe it is) DC voltage (about 6-14) going into the coil. If not I sayjest changing the CDI box they go out some times.

You may have dirt between the seat and the needle in the card. If you don't get a $2 in line filter before you do.

That's just a start. The first four things I check when a motor quits running are: Fuel, blocked airway (choke on?), spark, & compression.

You need about 85-90 lbs compression for the thing to run. Over 125 lbs is good compression

Good Luck...... And I'm not motorcycle mechanic.... But learned from the school of hard knocks.

 

yes the fire is good it is gettin gas i even rebuilt the carb to make sure it is getting compression how much i dont know i guess i'll get something to test how much compression it's getting

 

what is it doing, "ying,ying, ying, ying, " but not actually starting? Or no noise, nothing? Did you try to kick start it? (you need to engage the brake lever to kick start, can't recall if it's foot or hand-try both). I do recall dealers said they were bad for CDI's, but I don't know if that would cause you not to start. i know our battery was just a little weak and wouldn't start, so we used jumper and it started.
