plug reading help.

getting conflicting ideas about what's going on in this motor.

2 sets of pics, 1st set of pics is br9eix run for about 1.5 hours. 2nd set is br8eg run for 5 minutes just putting around to get some color on it. both are identical jetting, ambient temperature/elevation. on the first set of pics, the float level was bit low. also, timing was more retarded (just 1 degree less advance).


i'm thinking the first plug (which still ran fine) was a bit too cold, and a little rich. i'm assuming the carbon deposits all over is just due to plug too cold. there are no seal leaks.

2nd set of pics still a little rch somewhere, maybe hot enough of a plug now to burn deposits off.

1st plug.







2nd plug
