Another FS 400 problem

[Paul Smith]

Just been doing a little brush cutting down the yard and noticed a little annoying fault! When it runs hard for a while it suddenly looses power. If I turn it off and start again its fine or if I run it at full revs and keep it there it seems ok!

 

Any ideas please?

Try running it with the fuel cap on a little loose - it could be the fuel tank vent. Other than that, possible shorting of the kill wires or spark/plug issues.

 

Sounds a little strange but if the above doesn't help - try cleaning the carb and checking the metering arm height is correct

Thanks Spud. I will give it a go.
