Just tried to cut my lawn and my petrol rotary mower keep cutting out with
loud bands and some even had flames banging out of the exhaust ?

any ideas ?


Weak mixture. To test theory, does it run better with a little bit of choke?
Did you drain the fuel from it to store over winter?
99% of problems I have with garden machinery are caused by folk just
switching it off then putting it away for four months.
Cure - clean the jets.
Timing is when it will not start or kicks back badly - usually caused by
sheared flywheel key.

The correct way to store an engine is to drain out all the fuel from the
tank, then start it up and run it until it stops, (when the remaining fuel
in the carburettor float bowl is all used up).
A wee puff of WD 40 in the air intake as it slows down also helps but you
will have to remove the air filter first.
