Hi all.
I have a 1970s Early Bay 1600 single port, when I start it cold and after a run it sounds like its not firing on a cylinder, after about 5/10mins driving it does improve but not quite as good as it should do, also idles okay after engine is warm. Recent tune up (100 miles ago), I have checked all spark plugs and they look okay, taken apart carb and cleaned all jets, changed the coil. Any suggestions what next to check/change please?
If you have points check the gap. They could have slipped
Everything is clearer once you have the answer. Just goes to show that a compression test isn’t maybe first call but certainly worth a shot if initial checks fail. At least you know where you are now.
