[Public-List] Engine performance question

[Gordon Laco]

Thanks fellows - 

The fuel filter was changed last year...but this spring I had to do a carb
cleaning job in order to get the engine going.  I'll change the filter.

The filter on the flame arrester is several years old...  But there's no
smoke so I think the problem may be upstream of the carb in the fuel
system... Or a spec of dirt in the carb (again)

I'm getting really fast doing carb jobs....

I'll write how this shakes out.
