while running? bad spark plug or lean fuel mixture,from day one my troy built pops a little when not under a load, they are set lean at factory and ethanol gas makes them even leaner, if it is backfireing and not starting, it could also be a bad plug, faulty ignition component or a stuck valve
Incorrect Timing Can Cause Backfire.
what is making my Lincoln ls v8 backfire under the engine
A flame arrestor. This prevents a backfire from igniting gasoline vapors in the engine compartment.
The correct ratio for that particular snowblower engine is 50 parts fuel to 1 part two-stroke engine oil.
About 6.5
Several things could make a carburetor backfire. The engine could be out of time. the carburetor could have a stuck float, or the engine could have a stuck valve.
NO! It is too heavy an oil for the conditions the snowblower will operate under. Use 5w30 and do not use 5w40 unless you want to damage the engine.
No, backfire is usually caused by park plug wires that are installed incorrectly or an engine that is out of time. Fuel filter and pump will not cause backfire.
Engine Timing, Unburnt Fuel
