No fuel in tank; clogged line at/in the fuel tank; clogged fuel filter; carburetor needle valve is closed, fuel float stuck closed. Disconnect fuel line at carb, if you have fuel there, the problem is at the needle valve or float; if no fuel. the problem liies between the carb and the tank, next methodical check would be the fuel filter, etc.
No you do not. You will have to however have very specific jetting.
The correct ratio for that particular snowblower engine is 50 parts fuel to 1 part two-stroke engine oil.
32:1
50:1
you would adjust it by re-jetting the carborator
probably needs the car rebuilt
50 to 1 (parts)
jetting on 2000 srx is147.5,146.3,146.3. jetting on 2001 srx is 150, 148.8, 148.8.
IMO, Ratio depends on the carb jetting and oil quality. Try 32:1 (gas:oil) using good synthetic or syn-blend then jet the carb. With stock jetting that should be in the ballpark. Higher altitudes will require leaner jetting (smaller jet size not different gas:oil ratio).
be best to drain fuel and replace with correct mixture
Be sure the vent in the fuel cap is working.
