Need some help.

Have you checked the inlet? On a 2 stroke the inlet is blocked when the piston is down and open when the piston is at the top of the barrel.

 

you mean the reed valve?

 

no the inlet to the barrel, behind the reed valve

​

 

That pipe between the carb and the reed valve?

This is dry,meaning fuel isn't geting in.I'll take it out,and have a look.

 

Also check the when you start the bike (or try) that the bike is throwing petrol through the carb.

ie start with throttle open alittle with the carb off the block

 

I've got the inlet pipe in hand,it's fine,there's petrol going into the carb as I keep haveing to oepn the draining screw to let it out,could the carb be busted?

 

could be but if you are not getting fuel into the head then it would indicate the carb isnt push fuel through try opening the throttle and see what happens

 

Tride that eariler,the thortall valve opend and pulled up.

 

but did fuel pass through?

 

Just tride now with thortall closed,half open and fully open,no fuel is geting spat out.

 

ok so the carb is defo the issue

you say the jet is unblocked and have you tried the float?

 

Yep all cleand and shinny.

 

rebuild the carb is really the only thing i can suggest without seeing the carb myself :/

 

I tock the carb apart this morning and put it back togeather all cleand up,could see throw evrey jet,still dosn't expline why it didn't start when I injected fuel stright into the piston and tride to start it,proberly beacuse it was liqued and not vapour.
