FRONT END ALIGNMENT UPDATE

I have been setting 1/8"+ toe out as suggested in the JZR forum. The car drove OK but the steering was a bit twitchy. I tried setting to 1/8" toe in and it made a remarkable difference.  The car is much more stable now and the twitchy steering is gone. Well, how about that?

CARB ISSUES

I've been fighting a problem for the past year and I think I've finally solved it. When cornering hard the fuel would be thrown against the vent side of the carb to the inside of the curve and be forced out the vent. I think also a syphon would start and suck all the gas out of the carb. Coming out of the corner the inside cylinder would be dead and would take 10 to 20 seconds to start firing again.

I researched this to a great extent including contacting Eurocarb.com and the Triking forum. No solution offered did the trick. I tried cutting down of fuel pressure on the Holley pressure regulator but that made it worse. I tried looping the vent hoses high over the carbs and then down. That seemed to help but not solve it. Finally someone suggested bringing the vent tubes up high and into a catch can so no syphon could be started. Well that plus increasing the fuel pressure to 3# solved the problem. Hard cornering without a miss.
