My car simply looked like this. little filter for the old sube. Filters original style are ebay now (no local), and it got to be a pain. so I got one that has been around for ..oh...4 to 500 years of the internal combustion carb world for something universal . Bolted right up
This is after an ice storm drenched the car. The surprise the next day with it skipping farting and well a wet car sound...kept running anyway, but annoying. So i thought quick and this is where it is now, ready for anything oem wasn't.
1. natural heat rise by the choke gets trapped under bowl, cools choke, heats car in the car in cold. Nic ebalance.
2. bowl is plastic, one quick slam of any old sube hood gets the metal carb plenum touching it. That has always bothered me, the choke and feedback is sensitive electrical, and grounds where it sits. the bowl stopped this.
3. What goes up must come down. There is a phyisic in ice storms that drenches everything, this car keeps going, but gets reminded after it is shut off what kind of ice storm it just passed everybody in....(as old subes do)
4. the fast heat rise == better fuel mileage, with natural meter and warmer car inside as well when asking for heat.
