Theres SO much to learn, at least you're trying :D


Yes the open plate is the choke, if the engine is cold it should be closed to make the engine start better.


look own through the choke opening and there will be a plate, called a butterfly, that moves when you push the gas pedal.

There is another one under the one in back that is closed, so one on top and one further down, but the top one won't open until you floor it while driving.

The 'choke plate' in back is the vacuum secondary. It only opens when / if the gas pedal is way down and the engine is under load. It's near impossible to get to open sitting in the driveway


The green thing looks like a vacuum filter or check valve

something under that top plate is moving

but it doesn't stay. I pull the chain or push the pedal it moves but then comes back to the resting spot

what's the small green thing? is that a vacuum line or fuel?

i'm so ignorant
