With out the choke, the plug is not likely to have visible fuel condensate. If after priming it fires, sputters and dies then likely there's a problem with fuel delivery. If you're using fuel more than a month old, replace with new fuel (fresh from pump) and mix.
Check the following
- Cracked fuel line(s)
- Fuel filter
- Cracked primer bulb (may not be visible so replace)
- Carburetor mounting has become loose (vacuum leak)
- Carburetor gasket or adapter is cracked
If still doesn't run, then likely the carb needs a clean/rebuild or replace. You could try Seafoam (or similar) additive. There's also a possibility of a crankcase leak.
Keep in mind a china duplicate replacement carburetor for this unit is ~ $10, delivery included (USA), from Ebay or Amazon.
