What's the best way? Biggest concern is whatever i use coming loose and going threw the blower. I can't get my idle below 1450 and 950 in gear so it'd be nice to back it down some more

1450 is hard on drive when engaging...

tig weld.. hav you tryed the secondary screw? if you dont have a secondary adjustment screw you ned to remove the carb and flip it upside down and you will see the tiny allen head or straight slot screw..1/2 turn is good for 500 rpm's..

why not replace the throttle plates with new ones?a good place for carb parts is allstate carb&fuel injection.

New throttle plates are 5 bucks a pair.

some people don't like to mess with the riveted in throttle plate screws. replace them and you have another possible engine eating bullet. what about epoxy? if it comes loose, worst that happens is idle goes back up...

If "afraid" to do it is the problem for the op ..take it to someone who isn't afraid...It's not hard to do and shouldn't cost much to have done JMO

I would like to think his holley 4150 carbs have screwed on throttle blades. I suppose you could booger them up with epoxy to save a few bucks.

The majority of marine supercharged engines have no real need for drilled throttle plates.
