 FYI, we always hear about replacing the diaphragm , but i also replaced the spring air valve return. it made the idle smoother and for responsive. figures; they most likely were original from 1973! moss motors sells all the individual components for zs carbs. i ordered from the tr250/tr6 catalog,they use the same 175 carb. spring #365-780. $9.99 each. check out their website.
