A clogged fuel line will have symptoms such as you describe.
Does it cough(coff), sputter then run ok after ??? or does it remain constant or even cough, sputter and even quit running??

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!
