I sometimes struggle removing the old welch plugs. Any tips?
If the factory can't seal reliable using production tooling us carb hacks don't stand much chance.This is new, please explain what they use to seal them and why you have had issues with them?
Since the welch plugs usually cover the idle circuit any leaks will let extra fuel into the idle circuit and mess up the screw calibration at minimum. With a big enough leak the idle screw won't work at all and the idle will always be too rich.Cant say I've ever had negative side effects from it.
It is called carb cleaner like B-12. Spray it into the idle circuit and make sure it comes out the idle and progression hole in the venturi. BTW, how many carbs have you ever found crud/blockages under a welch plug?Beside how else are you supposed to make sure you have all the passages cleaned out?
How did this turn out?
