Yes it could if you in fact have a carburetor. Carburetors were fazed out during the 1980's.
You need to check the fuel pressure and the fuel FILTER.Most common cause of that is the float level in the carburetor is not adjusted right. / not getting enough fuel.
Flames coming from a carburetor are typically caused by a backfire, which occurs when unburnt fuel in the exhaust system ignites. This can happen due to issues such as a rich air-fuel mixture, faulty ignition timing, or a clogged exhaust system. It is important to address the root cause of the backfire to prevent potential damage to the engine.
The most likely cause of flames lifting off the burner is insufficient air supply to the burner. This can lead to incomplete combustion and cause the flames to lift off. Adjusting the air mix ratio or cleaning the burner ports may help resolve the issue.
Most likely, Your float is stuck in the carburetor. If it is stuck open gas will continue to flow into the carburetor bowl, then it will flow into the crank case and cause your oil level to rise. You need to take off your carburetor and adjust the float.
