Try looking at the fuel cap to see if the vent holes is stoped up.An engine needs air in the fuel tank to help push fuel through lines to carb.If you can breath through holes in cap it's alright.That reminds me the inside of fuel line might be caved-in too.Check this also.

I don't have sk-mag with me to see what kinda carb.you got but sounds like you've have a little trash in it.If your carb.has adjustment screws,turn high speed out bout 1/8 to 1/4 turn first.If not, (or this doesn't work) disassemble and clean real good.Look at fuel line too.Make sure that the tency-tiny hole in between the threads and the hole in the center of bowl nut are clear.This is where fuel gets into the carb from the bowl.That should do the trick.I always use a real small torch cleaning file to do this.Or a bread tie wire will do.
