These are pix before I started cleaning and tweaking.
Found a loose spark plug, which might indicate why there was a variable misfire, mixture looks good. Carbs look new, and the piston movement is perfect, which leads me to believe the backfire is exhaust-leak related. The hose between the manifold and the carb box (hot air return) is thrashed, but I'm not sure this is the culprit.
I raised the tire pressure (only 21 in front and in the rear.) Went up to 33 front, 29 rear.
I don't care what people said in the day. The TR7 is FUN. It handles like a slot car, with zero body roll. Once I can figure-out the backfire and fix the deceleration bypass issue, this thing will be one great little sports car!
And I also think it looks great...the wedge look is coming back, I tell you. Look at the "edgy" look in the new Corvette and Japanese cars.
I'm hooked!
