I have a os70 thats not running right. I took the carb off and stripped it down. I found the brass tube thats pressed in the carb case has a slit in it.its the tube that you see when you look down the throat of the carb. do you think thats causing my problem.

Hello!
Nearly all OS engine carbs has a slit in their carbs(for fuel). So yours are perfectly normal..
If you hav etrouble with your engine...have you tried a OS F glowplug!?
Fuel: 5-15% nitro, 18-20% castor oil(or syntetic oil)the rest methanol.
Propeller: Always APC (because they are the best).
12x6,13x4,13x5,14x4 or 14x6.
Open the fuelneedle apr 2-2,5 turns from bottom and start the engine with the throttle drum open just 1,5-2mm. Use a glowdriver, so that the glowplug is glowing bright orange ornearly white.
Use a 12v batteri of atleast 7Ah preferable 10Ah.

Best of luck!
Regards!
