I’m hoping together some helpful tips on how to improve my ‘59 Sprite. After a great deal of tuning work the car is running best it’s ever been. However it is still a bit Rich in the carbs but when I test drive the heat builds up in the engine bay and transfers thru the firewall making it very uncomfortable. Also, after my last 45 minute test drive I became sick from the vapors coming into the cabin. The heater is off but the gearbox tunnel is sucking everything up and pushing it thru to the cockpit. Notes: I have a stock setup with dual H1’s, original manifolds and exhaust. I have an O2 sensor on the exhaust showing 13’s-14’s. I did have the heater valve open at cylinder 4, and I neglected to reinstall the fresh air hose to the heater core (but I didn’t realize this until afterwards) any tips are appreciated. Thank you
