Can you tell us what you mean by "four stroke"? Do you mean you think it's missing?
If the idle is too low, you can try to adjust the idle screw (should be on the front of the carb) an hour and try it again. Remember, open the throttle a little so you are not pushing against the bore.
You can also try leaning out the bottom end a little bit. before I explain, this can throw off your tune. The low end needle is in the middle of your linkage on the carb. You will see a little flat blade screw. CW leans, CCW richen's it up.
Make sure your clutches are not dragging. If you are running a spring on your clutches, make sure it's not broke, or "they" are not broke if you have a spring per clutch.
If none of this works, you may try putting on a heavy weight flywheel. This will make it idle a lot better.

Hi sorry didnt realise i put the post in the wrong section. Took the carb off and stripped the jets out. Two things i noticed were that the low needle was very slack so when i replaced it i used a little thread seal aswell. The second thing was upon really close inspection was that the main needle's o ring was very slightly flat in one area (must have been like this from new).
I replaced the o ring and put the carb back in using a little gasket sealer around the mounting flange. The low needle was now much stiffer to turn eliminating it moving whilst under vibration. Anyway after firing her up and a few minor tweeks she is running lovely with a sweet idle and an instant acceleration. Gave her a few flights and it is performing great.
