It was running a minute ago....

[BAM]

I just purchased a used minibike. The engine started up just fine. I disconnected lights and whatnot and BOOM the engine doesn't start. I think its CDI but I'm not positive. Please help!

Reconnect everything back to original and see what happens.

 

[BAM]

No 2 wires are the same color. I realize this afterwords, there's no telling what connection went were.

 

[kartingizm]

maybe the kill switch got disconnected or the lights where connected to it?

 

[Badot]

Yeah, with pulling wires I'd think something with the kill switch/ignition system went screwy. Easiest way to check (if you mixed up the wires) would be to pull the plug and check to see if it sparks fine.

I just can't think of any way the kill switch could/should/would be connected to the lights...

 

[BAM]

I think I got it solved. I'll check to see if the plug is sparking (just wrench it out and pull the starter cord and see if it sparks?) but I think it's my fuel. I believe it's a 2 stroke engine and I forgot to pre-mix oil. Oops...

it would run regardless if you have oil mixed in the gas.

but running it with straight gas, after about a minute, it would seise or overheat...


make sure when you check spark that the threaded part of the spark plug is touching somewhere on the engine block, or else it wont work.

 

[BAM]

The spark plug sparks, I checked it this morning by wrapping a wire around the threaded part of the spark plug then running that wire down to the ground wire. I pulled the starter and it sparked. I cleaned out the carb (I think. I unscrewed the primer bulb and gas came out). The new 32:1 mixture is in the gas tank, I can see it in the gas lines as well. I pushed the primer bulb twice and tried to crank it up by pulling the starter cord 5 times. Nothing happened.... Still dont know what is wrong. Any other suggestions???
