Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello and welcome to just answer and allowing me to assist you. have you checked for a good blue crisp spark, and is there any contamination in the fuel?
ok thank you for that info/ next you said it back fires right
a couple of things that will do that is timing, lean mixture . so when you try to start it do you chock it or does this have an auto choke
so are you trying to start it cold first when it back fires?
ok then not being there I suspect that the auto choke is not closing enough to rich en the fuel to initially start it properly . Can you access the choke plate and see if it's closed fully or open/
so the choke plate is open, that may very well be our problem
does it seem stuck or just no spring tension on the plate
sorry had a glitch on the sight and didn't allow me to respond
ok try a few times to start with plate closed and then take out the spark plug and see if it is wet with fuel or dry
something is not adding up here first you said the choke was open then it was closed and you have a good spark and fuel but not trying to start? The fuel is new or was it sitting for a long time?
ok remove the spark plug and burn it off with a lighter and while it's still warm put back in and try
ok lets do this step by step, good fuel getting to engine , good spark.how old is this unit?
