Ivan kit and revisit to cold starting

[Falcon 269]

If the lead came out of the cap that easily, it's a fair bet the contact isn't as good as it should be.  Easy fix.

The tiny hole at the end of the pilot jet often needs poking clear even after soaking in cleaner.  A top E guitar string is ideal  ... assuming you play guitar, of course

Set the mixture screws to 3 1/2 turns out while you have the carbs on the bench. 

Hope this fixes the issue but let us know if it persists.
