Hi, I have just replaced the diaphrams on my twin strombergs without touching anything else. when I restarted the engine it’s characteristics are completely different eg it started fine but wouldn’t tick over until I adjusted the throttle screws. It feels completely different and not as smooth as before!
can anyone suggest what might have happened. the new diaphrams are stiffer than the old ones, does this account for the changes, if so I assume the carbs will need setting up and balancing ?
