I connected the fuel hoses to the WEBER carburetors and turned on the ignition. The fuel pump started to make the operation sound. But it didn’t stop. I thought it was strange and checked the engine room, then, I found that the gasoline was overflowing from the WEBER carbs!!! (There is no photo because I was in a panic…I’m sorry.)
I guessed that the floats of the WEBER carbs were sticking. I removed the top cover of the WEBER and took out the floats to clean. Yes, the floats were sticking as I guessed. I cleaned them and adjusted the float level, then, the overflowing was stopped.
However, the engine didn't start despite adjusting the float level. The first firing came, but it didn’t continue. After I checked several points I found:
- the fire on the sparkplug was okay
- the engine started if gasoline was sprayed from the inlet port of the WEBER
- the engine started if choke was operated and idle at 500rpm,
then the engine stopped if the throttle was opened or choke was returned - the accelerator pump of the WEBER for #3 and #4 cylinder was sticking
As everyone thought, the WEBER which slept for 10 years needed to be overhauled!!!
