Other Yahmaha pw 80 doesn't run

[ronan]

I have a 2004 yahmaha pw 80 with all new coil, spark plug, and CDI box. I try to start it but it won't pop over or anything. It seems like it has a faint spark but I don't know how to fix it. I've tried cleaning grounds and connections but it still seems like it has a faint spark.please help me

Howdy.
Have you tried using a small burst of starting fluid to see if it's getting fuel from the carburetor?
It'll run for a short time on starting fluid.
Starting fluid doesn't have oil in it, so if the bike is pre-mixed, you'll want to minimize the testing with it.

I've tried spraying starting fluid but it is getting fuel because I full the plug and it wet after I lock it over for some time so it is getting fuel and it feels like it's getting compression but I don't have a tester to see for sure

The kill switch is disconnected or tested as good?
Is there continuity/resistance through the stator?

I will check later today when I get home

Do the reed valves work ok?

 

[ronan]

I have checked reeds and cleaned the carb countless times and I checked the kill switch and there is no issues with it, I get continuity when on off position and 0 continuity when on run.

 

[MrMan]

How about ignition timing?

 

[ronan]

Timing is not my issue the problem is the amount of spark I get. The spark seams faint to me and the timing is good

 

[MrMan]

The only other thing is the stator…. Or your plug

 

[ronan]

I'll look into that

 

[MrMan]

Or it isn’t spark at all, your carb could be flooding the engine too. (Highly unlikely though)

Have you confirmed compression? If you can see spark and the timing is good, and you confirmed fuel, seems like a compression check would be a good idea.

I have confirmed fuel I do not have a compression tester but for an 80 the compression feels good and the bike doesn't have a ton of hours, the issue is the spark because it would only spark every so often and bad spark when it does spark

Get a proper spark tester .. and a compression gauge ... You can't test properly without the right equipment ..... Got to have the info .....
