Small Engines (Lawn Mowers, etc.): Help on hard starting engine, briggs straton engine, generac pressure washer

Question
Robert, I have a Generac pressure washer that won't stay running. It has had VERY little use.
Intek 6hp, Briggs & Straton engine, 121432-0021-E1
The engine would't start, it had not been run for quit awhile so I took the carburator apart, soaked it, replaced the needle & seat, and air intake gasket (torn). It still wouldn't start so squirted starter fluid in carb., it started for one second then quit. I've checked the plug, intake & exhaust valves movement and find nothing wrong. It it sits for 15 minutes it usually startes for one second than quits. It is always on full choke to get it to start. It just seems to be insufficient fuel but I don't know where to go except to replace the carb.
Your thoughts?

Answer
Stewart, It sounds as if there is a "lean condition" caused by a leaking gasket. Where the carb mounts there should be a "o-ring" present and look to see if the plastic cross over tube (under the coil) is loose or cracked....but look for any areas where air can leak hetween the intake tube and carb.....Let me know.....Bob
