Air Leaks-----How do you check for them...
#3
While the motor is running (Idle) lightly spray a nitro cleaner around the case, carb and black plate. IF the motor instantly dies, it has a air leak. Keep it away of the air filter. The fumes can kill it too...

OS 18TM stalls
I have a Revo with an OS 18TM. The engine will start and idle for quite a while. However, when I try to drive it, it will go about 20 feet and then die. I was thinking air leak, but I am not sure.
I swapped the exhaust, fuel tank, and replaced fuel line. The one thing I am noticing is when the truck dies, the fuel line is empty. I am loosing prime for some reason.
Would this be a result of an air leak around the carb?
Thanks,

Possibly an air leak, more likely needle settings.

I never check for air leaks...i just make sure i don't have any by using red silicone everywhere.
-Back plate
-Carb neck
-Carb boot
-Crank collet
-and finally white teflon tape around the threads of all carb needles.
This way you KNOW that if it doesn't run-tune, it's NOT because of air leaks.

I do like the teflon tape for needles that might be just a touch loose. It will definitely help keep them in place.

use soapy water and a brush. put fuel line on the hsn and blow while holding the intake and exhaust ports. Brush the soapy water on areas of concern.
