GPR-What would cause a piston crown to look dry?
Front cylinder/piston crown and head looks bone dry as if it's not had any fuel.
Plug colour looks good.New plugs fitted before test.
2 other cyls/heads look 'wet' and when you run a finger over them you can feel thefuel/oil layer.
Suspected a blocked carb-stripped cleaned, checked jets etc but all fine, and all passageways were full of fuel.
Anybody got any ideas?????

All carbs rebuilt with the same highs/lows.
it's a mystery-everything seems to be checking out-also all pulse lines are blowing nicley when I turn the engine over.
