I'm looking for advice on adding a block heater to my 91 DD51T Carry and hopefully solving my cold start issues. I live in the Midwest and our winters aren't usually super cold, my truck however does not like to start when it's below 35°F (2°C). I'm trying to figure it out before it gets cold and decides to strand me at work again.
Last year before it got cold I replaced the carburetor (the choke was sticking), starter, battery, and added one of those sticky pads to the oil pan. The truck still seemed to struggle.
Any ideas would be greatly appreciated. Thank you.
Truck specs: DD51, F6A engine, 4 speed manual, tune up done about 4 months ago (plugs, wires, coil pack, distributor cap, new vacuum lines), timing -5° TDC, air/fuel ratio is a bit on the richer side, idle 950-1000rpm, valves lash was set to 0.10mm on a cold engine.
