Stubborn Carb Screws

Recommended Posts

Hi everybody.

I just bought a 1986 CR 125 in need of some work. Right now I am working on cleaning the carb but the screws I have to remove to remove the bowl are stuck. I hit them with some seal breaker and they still won't budge.

Do you guys have any tips or tricks to remove these little screws or should I just drill them out or something like that?

Thanks!

needle nose vise grips, then buy new socket head screws

many years ago when the mikuni reps were at the tracks helping racers get dialed, someone asked about those bowls crews. the answer was they were soft and used a odd size phillips slot for a reason- so the casting wouldn't get cracked from over tightening. take that piece of trivia FWIW

I have used an impact screw driver in the past. they work well if the phillips head of the screw isnt stripped completely.

I have a set of screwdrivers I got at Ace or True Value hardware that have "antislip" grooves in the tips. Work very well. Those little screws are not meant to be very tight, just firm.

those screws are not philips screws, they are JIS screws, they should have a dot on them

buy a set of JIS screwdrivers to get them out, swap out screws for allen or regular philips

+1 on the impact driver they teach you that at mmi even, but make sure its a quality impact driver that rotates smoothly so you dont have to strike it so hard.

A #2 "recessed" phillips tip for a 1/4" magnetic screwdriver works wonders. The local Ace hardware sells the tips for about $1 each. The "recessed" #2 tip has a narrower shank that allows the tip to engage deeper into the screw head than a #1 (which causes it to strip).
