Suffolk Punch 35s not starting
 

Hello all -
i purchased a second hand suffolk punch 35s petrol lawnmower a few months ago. - It's been a great mower though currently it's stopped working/firing over. thought maybe it was because i added old fuel - so i drained this out and put new petrol in - and still nothing. Its sparking so seems strange - I also cleaned out the carburettor but no success. - this wasn't the the best solution - but i took the spark plug out - put a thimble of petrol in where the spark plug goes - spark plug back in and pulled - and it worked and fired up for 5-7 seconds but then died out. Seems to be a fuel blockage? - but i've tried all avenues with no success or noticeable blockages - would appreciate and advice you could give an amateur Best regards Parkie.

The first thing I try in such a case is to remove the air cleaner, squirt in a
little fuel, and start it. repeat several times, or if you can figure out a way
to squirt lightly while it runs, keep it running that way for a bit. Sometimes
that's all that is needed to get the fuel flowing. Using the choke or primer
appropriately can help sometime also. Otherwise, you will have to find the
problem in the fuel line or carburator.

Is there a fuel filter on this unit? Does it pass fuel? If there is a drain in
the bottom of the carb, does it drip fuel when opened?
