Stromberg hot start problem 140-160



Tuning Strombergs is not a commonly addressed subject but British car circles tend to know them well; your local MG or Triumph mechanic will probably know those carbs better than your local Volvo mechanic does.

The obvious caveats apply, of course: don't mess with the mixture until you've fully sorted the ignition and valve adjustments...

I had a California-spec vehicle so I didn't have full control of my mixture, as California had some special pollution requirements. On most vehicles a special tool is required to adjust the mixture. There's an air bleed screw on the side of the carbs, but you would be well advised to mess with that only when you've got access to someone who knows Strombergs.

I've got the green book for it, which includes the complete factory instructions for tuning the carbs. I'll be happy to scan those pages for you when you get back. You'll be surprised at how useless they really are. But they might come in handy, you never know.

Again, you opened the throttle all the way, and held the pedal solidly on the floor the whole time while cranking, and the car didn't start after ten seconds with the throttle wide open? No choke was used? If all this is true, something's up. Don't even mess with "mixture adjustments" until you're past that stage; the mixture adjustments don't do a whole lot on these carbs and a gross problem like that is likely to be something more obvious, like a stuck air piston or a clogged air filter or a punctured diaphragm.

Anyway, revive this thread when you return and I'll scan the relevant pages for ya.
