Hello my name is ***** ***** am I speaking with?
When you say the engine has run excellent in the past. Was the past 2 days ago, 2 months ago... or 20 years ago?
Was the fuel all brand new, or did you mix new and old? If mix, how old was the old stuff?

added about 10 gallons, of prem, to last years gas, ran excellent with the muffs on in yard, vro pump works
Expert:  Jason replied 1 year ago.
If part of the gas is from last year then all the gas in the tank is not going to be any good. The tank will need to be pumped out. Do you have a fuel/water sepererating filter between the engine and fuel tank?

Good morning, just checking in, any progress?
