how much fuel would be on the open level . i put in 2 gallons into an empty tank and still didnt wanna run fine until it was switched to reserve . and the petcock is brand neww. i dont think it should clogged already .is there enough gas that the fuel is over the "open" or "on" level?
otherwise that side is probably clogged up
i see the reserve filter is lower then the open . but is there a difference in gas flow going to the carb . ?sounds like a clog petcock.
the differences between reverse and on is the level. take your petcock off and you see the difference.
there shouldn't be any difference.
and the reverse should be around half a gallon difference.
I always run on reserve, it flows faster.......
