Yesterday I cranked the old mower which I had tuned up by a professional just over a year ago and when it warmed up it ran poorly and would hunt and surge when running more than idle.
The fuel tank at that time was very low so I topped it off with fresh fuel and basically had no effect. I had a similar problem last year at which I could get a bit better performance by pulling on the choke, but this time that make nearly no difference.
Do I have to take it back to the pros or is there something that I can do? I heard this model has no mixture screws to check/adjust. The unit has a 19.5 Briggs & Stratton V-twin engine.
Thanks!
