success with the Gravely.
not sure I can blame it totally on this but when inspecting the pack of four new
Champion plugs I bought, I noticed two of them were way misgapped, very tight like something had wacked on to the end of them.
So I found the two new ones that were gapped properly, and put them in.
Started immediately.
but did not purr.
some popping and burbling, I think more than usual.
probably due to lack of use and maybe some gumminess in carb jets. Vanguard 23 twin
or perhaps 25...I think that chrome exhaust tip has to add at least two horsepower.
my cheapo spark plug gap setter, from Craftsman by way of northern Mongolia, could not fix the two since the gap was about .15, too low for the beginning opening.
Need to secure them and pry apart, well not pry, am sure that's not good on center electrode. Set those two aside to give to my favorite mechanic.
I was fooled, first one I inspected looked perfect so one right next to it must be right too?... So I didn't check the gap on the second one and it was almost flat.
