Getting some snuffling through the carbs, still feels sluggish. I think i am pretty close on mixture. Got a feeling there is some movement back and forth on my bellcrank which may be making the two halves of the engine "fight" each other. How she look?
.................Looks slightly lean...plug gap appears ok....And it appears that the greyish coloration on the spark plug threads is ..anti-sieze...and the plug has not run very long. Anti-sieze SHOULD be used on the spark plug threads., Especially if you know that you will be removing and installing plugs from a HOT engine. Removing plugs from a HOT engine is when the heads aluminum spark plug threads are prone to damage...cracking, breaking off, stripping etc...I hope you used, or will use, anti-sieze, as well as everyone else.
