Try a 350 and see what it looks like. Plugs are cheap.

That doesn't look bad to me, but its hard to really know what your seeing unless it's in your hand, not on a monitor.

Give it another shot but only WOT for 10 seconds ( more than adequate) applying the brakes a little so that the engine pulls hard.

It is not speed that produces the smoke ring it is pulling hard at WOT.

So I did as blaster told me to make another run on the 340 while holding the brakes and to me looks better what do you guys think

I really think your good. Sweet, now I have a good baseline on where to start!

I like them a little darker than that, I'd try the next size up and plug chop again.

and remember, if it's spot on/borderline as shown, it'll fry if ran in 20-30 degree colder temps than the test was done.

OK ill do a pass with a 350 and report back at you guys,
i rather be safe than sorry even do we dont get berry cold here in fl, rather loss a little power being richer on the main than to lean and fry a piston

Blaaster · Nov 25, 2015

Na little loss of power is so much better than a loss of a lot of hard earned cash.

One size bigger , two if you are expecting colder weather.
