/6 wont start/ run with choke
My 1965 valiant convertible has its original 225 /6. It will not start with the choke connected to the heat operated actuator. When it’s warm I have to hold the pedal to the floor and it’s cranks for a significant amount of time before sputtering resistantly to life. Once running it runs smooth and perfect. At 55 mph you would think it was an electric car it’s so smooth.
I replaced the Carter carburetor that had worn out sloppy throttle shaft bushings and had been sitting for who knows how long with a brand new rebuilt unit. I replaced the brittle old gasket and installed a brand new spring heat operated choke actuator and its doing the same thing. It only starts with the choke wide open and the throttle pedal fully pressed to the floor.
I’m thinking it might be low compression due to valve adjustment, old worn out piston rings could be the culprit. I’m sure it still have valve seats designed for leaded fuel. The odometer is showing 3012 miles and I’m assuming this is 103,012.
I want the engine completely stock and to operate as it should with all the factory components fully functional.
has anyone else had this problem?
before I start chasing things around indefinitely only to have no results I’d appreciate if the forum could point me in the correct direction.
Thanks in advance for any information.
