258 cid MC2100 issues

[Lumpy Grits]

Problem is I CANT KEEP IT RUNNING it starts and dies like its Starving for fuel. It sat for over Six months and I think I have carb issues over Vacuum leaks. You can usually keep an engine running long enough to find a leak even with a BIG vacuum leak. changed the fuel filter, and checked the flow, The accelerator pump blows atomized fuel when you pump the pedal. When I get home from Texas I may have a couple days off I think Ill pull the carb and rebuild it My guess is its got trash in it somewhere.

Check the fuel pump for psi and see what the carb's float setting is?
Make sure you don't have a pinched fuel feed line, and that the clamps are tight so the pump ain't suck'n air.
Good luck,

Turn the two carb adjustment screws out half a turn see if it will stay running. Tap the side of the fuel bowl with the end of a screwdriver as well.
Do you see fuel squirting in if you turn the throttle shaft?

Also-Be sure BOTH idle mix screws are turn out the exact same amount too.
