I have an older Tru-Test snow thrower with a 3HP Briggs & Stratton moto
on it. The only way that I can get the unit to start, everytime is t unscrew the spark plug, pour in a shot of gas, and put the plug bac in. It will start everytime this way. It appears that the manua choking system is not working. I am not an expert on Briggs & Stratto equipment and I am not sure where to start investigation

One other thing to check. Sometimes on snow blowers, the gasket between the carb and the engine goes bad. Dries out or whatever. I've had a case where the choke was fine, but air was getting in through the gasket.
If you can't find a replacement, just give it a light coat of Permatex #2 non hardening gasket sealer, and put it all back together.
Look in the carburator throat, there is a circular disk that swivels , find it and the attached link, it may have come off or be jammed, make sure it closes on ckoke and opens on run.
