Carburetor Pump pressure valve and Pump vacuum valve...

Post by boeing7873 »

My forward carb pump is not injecting fuel as my back carb. I changed both pumps but I am starting to believe I have either clogged jets or the pump valves are bad. (Parts 1-40-49 and 1-40-51)
Anyone with experience on such a problem?

Thanks,
Jerome

Found the obvious problem. I took the carbs out and found that instead of the pump suction valve, I had installed the starter jet in its place. (parts 01-40-36 instead of 01-49-51.)
They have same thread and will interchange.. but with the most undesirable results.
For the records.

Glad it was a "relatively easy" fix. That probably also explains the lack of advice from people. :)
Enjoy your holiday!
