I did get the fresh gas in the right tank (lol) I couldn't tell if the cylinder walls rough(no light early) but will look again,my buddy thought maybe a crack or scratch in their when he looked, which would be bad..And should have been my question,if scratched or worn or cracked time to rebuild and what would this cost parts wise allowing I can do it myself? Oh my buddy pulled the plug out (new plug) poured some gas straight in and nothing,then he takes the plug out,attaches it too the plug wire and holds it down to the head to check for a spark and pulls the rope and sure enough it sparks plenty good and lights the gas,a big balls of fire and burns his beard(lol) had to throw that in as dumb things not to do..But it does seem to sending plenty of fire to the cyclinder.
