Reply to "Motor stalls when braking hard"

Stalling during a panic stop is usually one of two things: either fuel is slopping out of the float bowl vents and flooding the engine or the engine is starving due to fuel slosh in the bowls. Neither are easy to diagnose since both are transient problems that happen only when the car is rolling. To fix the first, traditionally one takes a piece of tygon tubing and joins the float vents in a fairly tall loop, with a single venting hole in the top of the loop, up inside the air cleaner opening. The second required jet extensions, or turning the carb(s) sideways or stuffing blocks inside the bowls to control slosh. If your problem is something else, first look very closely at your motor mounts, to be sure the rubber isolaters aren't deteriorated or the mounting bolts broken, allowing the engine to shift under braking. Both are common & either can cause all sorts of bad-news re stretched wires, cracked hoses etc.
