Hello Everyone!
I'm putting the finishing touches on my Midwest Cap232 project with a Brison 2.4/40cc engine. The motor last ran 2years ago... Well lo and behold... It won't run now....
The fuel system is brand new. And as of yesterday I confirmed the plumbing is correct and working.
The Brison Ignition is working, if you prime the motor by turning the prop with your thumb over the carb it will pull enough gas to fire and run on the prime then stop...
The motor was stored in the house on the airframe and was clean and dry... The diaphram appears to be pumping but the carb doesn't appear to be sucking gas on its own...
Any ideas???
Thanks,
Ed "Hibrass" Harley
Ed, it seems to me, from what you describe, that the pump in the carburetor is not working. Remove the single screw from the plate and look at the rubberized sheet. Make sure that the U shaped check valves are not stuck and lie flat against the casting. Make sure that the screen is clean. Screw the needles in until they gently seat. Count the turns. Move them back out to the original setting. If you don't have any luck here then get a carb kit from Ralph Cunningham at RC Ignitions.
