weired. mine seems to be working pretty well, altho it hasn't been run enough to learn much. I still haven`t fixed my oil leak so I could mess w/ it. it does seem to be real rich what little it has run. 17 buckets of driveway sealer (tar) down, still need about 3-4 to finish. spreading that stuff w/ a squeegee in a 100 degree heat is fun !
