I recently installed a new Holley Brawler 600 CFM carb on my 1968 Mustang 302. The shop that installed my rebuilt engine put that carb on and wired the electric choke to the starter solenoid. In a matter of days after getting it back it started running very poorly. That is when I discovered the choke plate was not opening properly and how he had wired it up. Too much fuel, too little oxygen fouled the plugs and got gas into the oil. I rewired it to the heater fan fuse using one of those fuse splicers. Fixed the problem. I also replaced the new but now fouled plugs and changed the oil and filter. I have an appointment to take it to someone that knows what a carb is in the spring. The fellow I am taking it to is who I got the carb from, The Carb Shop in White Bear, MN. Pat Ott, the owner, asked me when I bought the carb why I wanted an Electric choke. Asked me if I drive in the winter which I don't. In hindsight he was right. It ran fine before on the old Holley with the old tube setup. Just added another level of complication that really wasn't necessary.
