Gy6 starting issues need help

[RyanosAlien]

Hey,

Okay I have a 2005 alien longbo lb150T-19 and bought it on an impulse buy and been trying to get it started ever since,

What I've done so far
Pulled the carbs and cleaned them
Drained old gas cleaned tank and refilled
Checked compression "good"
Replaced filer that was crushed for a cone filter I had laying around off a gokart
Adjust air/fuel to 2 1/2 turns.
Checked spark which I couldnt get to spark.

So my question is there a way to check the coil pack and or is there something else I need to check the spark plug in it looked brand new a NGK c7hsa and tryed to get spark using my motorcycles plugs and couldn't get spark.

Ps on 1 attempt to start it after cleaning the carbs it did start and idled up and down real rough and died out and hasn't started since.

Any thoughts?

If at any time it turned over and it actually tried to start up, forget looking for ignition problems - you don't have any.

This leaves fuel or air/vacuum issues.

Try spraying starter fluid inside the air intake box and turning it over. If it roars to life for a few seconds (as I expect it will), then you need to re-check the carburetor and vacuum lines.


If there is some sort of vacuum leak, the engine may never develop enough vacuum to draw the gas up the jets. If there's no fuel in the float bowl (or the jets or other carb passages are plugged), you likewise won't be able to start.

Could be valve clearance but if you've got good compression I doubt it but worth a look.

If it tried to fire up once I'm with shadow fire you must have spark, of course it could have been the last gasp of a failing CDI or coil.

if you checked spark and you have none then my first suspect would be the CDI you can pick up a replacement for about $10 on amazon. next suspect would be the coil. not suggesting you start throw parts at it but Those are cheap parts and even if the ones you have are good those are good spares to have laying around for the purpose of elimination.

Here is a decent article on trouble shooting the no spark condition.

Good luck and keep us posted.

Just because it started doesn't mean your ignition system is fine. I'd still check the coil, and CDI. From experience, I suspect the coil. Change them both, you can pick them both up for under 20 bucks on Amazon.
