Here are a few things to look over, and a question for you.
Look at the head bolts, tighten them if required. Using a needle or small drill bit by hand, make sure the muffler pressure nipple is clear.

What fuel are you using?

[heli mad]

Iv done all of that Mate. the fule im using is wildcat 10%

Maybe your pipe is bad. I know it's not necessarily an easy or inexpensive thing to do, but have you tried a different pipe? Also, when you checked the muffler pressure nipple, did you check both ends (coming out of the pipe and going into the tank)?

[heli mad]

Iv not tried a new pipe yet but i have checked the muffler an it is ok i have been told to clean out the muffler with carb cleaner i dont no if this will work!

dont use carb cleaner, you can kill the o-rings. use denatured alcohol. like $12 a gallon at lowes. to mee it sounds like a worn motor, piston ring or bearings perhaps. Clean the carb first, and borrow someones pipe if you can, if that doesn't fix it, well.......:(

There are o-rings in mufflers?

Some do have o-rings, but only in the header AFAIK.

Sounds like 1/16th - 1/8th turn out on the mixture screw would solve all your woahs.....

[RotaryBliss]

you said you changed all the fuel line's. The clunk line also?

[phantom1500]

if you pinch the fuel line when running how long does it continue to run for? you are looking for around 3>4 secs and a clean engine cut. thats a good indication of you bottom end mixture. my os32 is pretty much set to the manual needle settings and runs spot on. has it got a cast muffler or an alloy one, no leaks around the exhaust port?
