Your carbs are set up the same as mine; My engine is a B20F as far as head,cam and exhaust are concerned. I'm using an MSD6A ignition with Pertronix kit and Pertronix coil. Timing is at 20 deg and premium pump gas. Simmons sport exhaust.

I found it necessary to set the needles richer than you; they are currently at their richest setting; probably a bit too much for 90-100 deg. days, but the rest of the time it works quite well. I'm guessing you have to use some sort of ethanol blend gasoline?

On a side note, do you have any problems with the idle being a bit low after a hot start?, and taking a couple of minutes to clear.

Also do you find gas seeping out of the overflow hoses on the float chambers after shutting the engine off?

Bill, in Oregon
