Forst ST6P won’t start

[Mick Dempsey]

Well, there are better peeps than pan me to diagnose, but I’ll start..

 

A petrol engine like that it’s either spark or fuel.

Have you checked the plugs for a spark?

That sounds identical to my eliet shredder with the vanguard engine.

Turns out the visible inline fuel filter just needed moving slightly into an upright position for the fuel to get through, it then started, but if when running I moved the filter off upright, the engine cut out.

To eliminate the spark plug, have you taken it out and cranked to see if there is a spark?

First I’d look at the filter then the plugs see if there’s a spark then the off switch solenoid my bet is on fuel 

check safety circuits

Thanks good points, I’ll check that when I head back this afternoon. Also to note about 6 months ago I lost my fuel cap whilst filling up and forgetting to put it on whilst driving away so some debris got in the tank though not a major amount. Is it possible this could have filtered through causing a blockage?

When did you last change the filter?

It’s not been changed since I bought it a year ago. Had a service 4 months ago and nothing mentioned about the filter so assuming all was good with it. I had a look at the filter earlier and it’s hard for me to tell if it needs changed. Didn’t look too bad in my opinion. Got a mechanic friend coming to take a look in a hour, hopefully he will know otherwise I will post some pics.

Is it a clear filter you can see the fuel in? If so observe it when you crank the engine to see if you can see fuel flowing

[Cactusjack1993]

Fuel is going to fuel filter but isn’t filtering through.
