I did start with the tank, flow was anemic, but gas line had a bad kink - made up a new one. Flow's fine now.

Thing is - I'm less concerned with figuring out what the problem is at this point. It's more a question of IS there a problem?

Tractor's running perfectly fine now - but I've got a nagging suspicion that I found a lucky balance of leaning it enough to not bog with a slightly restricted gas flow.

So my main question is: CAN an M carb draw more gas than is coming in IF the gas is flowing properly.

With the main jet completely out - under moderately heavy load - would it be normal to drain the carb enough to starve the engine?

Forget about how I SHOULD set it - I'm just wondering if it's physically possible to drain it in a worst case scenario.

OR does its emptying automatically mean the gas flow IS restricted? OR float level is too low?

Anybody know for sure?

Also wondering if there's a way to quantify a properly flowing gas line - from the tank. X number of gallons per minute or X time to fill one gallon - something like that.

if not - it might be nice to establish one.

I see the question of restricted gas flow come up so often here. Might be nice to have a real test (other than "looks good") to be able to cross it off the list completely when diagnosing a problem. This one looks fine to me, but maybe I'm wrong.
