Initial Startup really bad idle - Help Needed
paulbaker1954:
Fixed
Pulled carbs and found 1 blocked and 1 partially blocked pilot jets. Cleared with a wire from wire brush (don't play guitar!!!). Also liberally sprayed through all mixture screw holes with carb cleaner
Purring like a kitten now 😀😀😀

Thanks for sharing the result, may help the next of us to encounter similar issues to get to the culprit quickly.
Ashdowner:
I have exactly the same problem - idle shocking to non-existent yet over 3000rpm as sweet sounding as any engine could be. Looks like a carb clean for the new season.
totty:
If you're not planning to use it any time soon just poor some redex down the fuel pipe to fill the bowls and leave it. You know the carbs aren't filthy as you've already stripped them so I can't see it doing any harm. I've cleared pilot jet passages this way before.
