Hi Vince,
        Thanks for suggestion.  Sounds like using single electrode and 100LL
gas with lead may indeed be the source of the problem.  Don't think it
is ice as aircraft is hangared in heated hangar >50F and this occured
right after I rolled it out and started it up.

I have the stock NGK plugs handly just thought I would try the others.
I will let you know what the plugs look like when I pull them this
weekend.

Get that motor mount done so you can hang the engine and really start
having fun{:>}.
