Hi

My petrol lawnmower starts almost first time but it only runs for
between 30 and 40 seconds before it conks out, it won't restart
immediately but after a few minutes it will start and run for 40 about
seconds again.

It started doing this at the last cut of autumn, (hence its not an
stale fuel problem). I added a little redex to the fuel but it made no
difference.

Just tried it out now and its still suffering the same problem.

Any ideas, the engine is a Honda GCV 135E.


TIA

Paul
