Two-stroke not starting!

[dylan1951]

Hi there,

I'm trying to get an old 2 stroke 50cc bike going that hasn't been started for about a year, with no luck so far...

It has 1:25 fuel in it like it specifies on the bike. The fuel tap is open, and the switch on the handle bar is on. Iv'e tried starting it with the choke with no luck.

Iv'e even tried replacing the spark plug because I had one handy. For some reason it just will not start!

Any help is greatly appreciated!

Thanks, Dylan

Whip the spark plug and lay it against some metal part of the bike.
Crank it. You should see some spark.
Take the carby bowel off and see its got petrol in there.
report findings when done.

I'm quite sure that the spark plug is fine because its brand new out of the box.
But i'll open up the carb and see if there's any petrol now.

Thank's for quick feedback.

Compression, spark, and fuel are estentials.
Check for fuel flow by opening a small carb bowl drain screw at the bottom of the carb.
Check for spark by resting the spark plug on the metal cyclinder or cyl head, and kick start the bike.
Check for reasonable resistance in the engine while using your hand to kick the engine over.(plug must be fitted to the engine again).
Good luck.:msn-wink:

It looks like there's petrol in the carb...

Is that bad? I'm not very good with these things.

Thanks for your patience.

I don't really care if the plug is new or not.
You take the plug out to check if its getting power.
You do this as advised.

Good luck

Check the plug for spark.

...take the risk of learning something...take the carbs off and figure out how simple they are to clean and fix...I have a feeling that this has been talked about elsewhere here in the last few days...

Check the plug for spark.

+1. New plug wont spark without something to spark it.

Ears must be glues on.

Moving on.

Stale fuel.

Drain the carb bowl.
