Hawksmoor Mower Surging

[mikemlambert2@gmail.]

I have a Hawksmoor Mower [XSZ40B][1 year old]and it surges badly since putting it away Last winter. It ran fine before that. It stalls out when I try to cut grass most of the time now and It need lots of choke[Red button pushes] to get it started from hot.. I did not drain the fuel when I put it away. Since then I have drained and refilled the tank with fresh fuel and problem was still there. I removed the carb and main jet and ultrasonically cleaned it in thinners. Then blew out all the jets and small holes near the throttle butterfly with an airline. I did not actually remove the emulsion tube which sits behind the main jet I think but I did blow this out. Anyway after re-assembly the mower still surges as before. I will change the plug now. When I remove the drain plug fromt he floatchamber the fuel comes out free flowing so I assume that any restriction in the fuel supply is unlikely to be the cause. . Any comments??? Anything else I should try please. ???

If that's your actual email I'd take it down before you start getting all sorts of rubbish.
Also get more response in the gardening section

You're certain it's not running lean, and also that the governor system is in good condition, no weak/overstretched springs?

I have the exact same problem after a winter in the garage. Tried everything I can think of including removing and cleaning the main jet / emulsion tube, also checking the idle jet for blockages.
Any would be appreciated.
