So Blykins I reached out to Scott but no answer.
Here's the situation and what I sent to Scott.

Scott hope your enjoying Football Sunday. Its Scotty from Colorado who has a carb from Blykins for my supercharged cobra. I have relocated to Dallas Texas and want to adjust carb for the altitude, humidty temp etc. I have attached the build card that came with carb. In Co the carb was running super rich so I backed jets of to pri 74 and sec to 84. Car ran better.

Here in Dallas the car runs decent until highway speeds where it seems to sputter when hitting throttle. Any suggestions are super appreciated.

Attached is a picture of one of the plugs.

Thanks.

Btw, the car pulls like a bat out of hell from 1st to 4th. So much so I haven't gone above 4500 because I feel like wheels are going to break loose for good.

When cruising at highway speed in 5th and pressing accelerator the car hesistates. If I drop into 4th then car seems to steady out of hesitation.
Fuel pressure is consistent at 6 to 6.5.
Car idles at around 900 to 1000.
Timing is at 36 and seems best setting.
Colder plugs and correct gap set.

Thoughts?

Move to PV 6.5(dependent on vacuum pressure?
Increase sec jet back to 86 or beyond?

Also not to put you on the spot but in a general sense what does Scott actually do with these carbs that the factory doesn't already do? I ask because the build card looks to be exact to what QF sends the carb out with. Does he light insense and perform chants until he passes out before a premonition comes to him.

But seriously I'm curious since I've been asked by others too.

Thanks
