Simple carbs to take the top off of.

Needle and seat right there hanging from the top. Usually the rubber tip on the needle gives out first. The seats are simple solid brass. hard to wear them out, but they can corrode.

I use a 1 quart tin can with a gas hose ln it to start engines when there is no fuel supply. Raise them above the height of the carb and let it Gravity feed.

Can take your fuel supply and fuel pump out of the equation for a test this way, see if the carb still leaks when idling.

Saftey first, plug your gas line from the tank, and drsin your fuel pump and guel filter before the test. Don't Want to be spraying gas around .
