Small Engine Troubleshooting Problems? Ask a Mechanic Now.
There is no adjustments on this carb. You have a gov spring that controls the throttle.
to make the engine rev higher/lower, you would just bend the front metal part that the spring hooks to. backwards bend gives you less rpms, forward bend gives you more rpms
one of these setups is what you have? the gov springs are the same just hook to diff parts, and one has the extra spring going to the vane
That is the mechanical governor. there should be a hole on the end, that it goes into and then it reaches to carb and hooks into throttle plate hole. the spring then hooks from throttle rod, to front tab.
Setting the Gov is pretty much trial and error. I would also but once you get it close, move to adjust the spring holder on the front.
Is it possible for you to upload a picture of your set-up. I can use your picture and label everything for you and send it back to you.
not a problem, I will be here
