Take off the air boot and guide it in with your fingers. If it won't go in then you can assume there is something in that itty-bitty hole it goes in.

Ohh air filter? Iv got the carb off so I have plenty of room but it still won't drop in, iv got it into it about one quarter of the way so I only have a quarter of the throttle. Could the needle or slide be damaged stopping it from dropping in all the way ? And I can't get hold of one anywhere

Sounds like you don't have the slide lined up in the carb. It will only go in one way. Look at the slide and you will see a slot in it. It has to line up with the pin in the carb body for it to go all the way down. If it's lined up and still will not drop in , then the needle is hitting the jet.

Never had a problem with doing it before now. Been trying for over a hour. What you mean by hitting the jet? Could the needle ave dropped down by any chance? What about moving it up a clip or 2?
Thanks for replying buddy

Ok, that is what the slide slot has to line up with, as I stated in the previous post.

I am beginning to think you are just pulling my chain.

I have a pic but don't know how to upload it. It looks like a piece of the metal has somehow torn and is sticking up

---------- Post added at 01:26 AM ---------- Previous post was at 01:24 AM ----------

Yes the slide has a slit to line up but this little metal piece looks really abnormal and is the inside of the carb not the slide surely it should be smith for the slide to go up and down freely?

There is a pin but this metal bit is on the opposite side:/ its all jagged aswell wish I could show you a pic could I email you it?

Best you up load a pic..... There is a guide pin for the slide which has a groove on the slide to line up with. Then there is the idle screw adjustment, opposite the guide pin....any abnormal gouges should not be there......

Do you have Facebook? I upload pics to my Facebook then select the photo and open in a new tab.... This gives a none account linked tab that you can copy paste onto here....if you desperate that's what I've always used.... Or photo bucket...
