I'vet a 390xp that has been woods ported and has a ported muffler. The thing runs fantastic, but once its good and warm it is difficult to get started again. It will sit and idle all day long with no issues. New intake boot, new base gasket, new exhaust gasket,new crank seals, all new tygon fuel lines, new fuel filter and an unlimited coil. Can anyone help me understand what I am missing for it be so difficult to restart. Note, if it has been sitting and is cold when starting, it will start within 2 pulls. Any advice would be greatly appreciated.
