Hi All, Hope you're all well. So here is my problem, spitfire 1500 1976, when its warm, its great runs really well, but from cold its rough, won't accelerate properly etc. As it warms up it stays the same rough running until a few minutes after maximum temperature is reached ie the thermostat opens, then a few minutes after further running all is well. It starts OK on choke with small amount of accelerator pedal etc. The timing is 10 BTD, dwell is good (yep still on points but will replace later with a spark rite unit). The carbs are balanced and the mixture set as per book and colour tune checked (plugs a little black after a good run, not too much, I think this maybe old piston rings leaking a little oil, but no smoke out of the exhaust). Is it me just not remembering how things were in the past ??
My 72 GT6 has cold start enrichment on the front carb only. There is a link tube between the carb’s, but the port isn’t drilled-thru on the rear carb so it doesn’t do anything. Anyone else got this setup?
Hello My 1200 Herald is poor cold starter. It takes 3 or 4 attempts to get it to fire. Once started it runs ok but does seem to need a small amount of choke when driving in the cold. I try to start on full choke. once started and then turned off. It fires first time on subsequent starts. Starts well once warm. Any ideas how I can sort I have new fuel pump, thanks leads and distributor cap ready if needed. Other point of note my nephew cleaned the carb when I first got it over 4 years ago and said there was a missing ball bearing is this allowing fuel to drain from carb, hence need to get fuel in before it starts? Any Help appreciated thanks Andrew
