Default carb question

i have a some carbs i would like to try on my boat. they are a pair of weber's off a mid 90's 390hp Merc 502's . i want to put them on my small blocks in my scorpion. they are basically 260's with mild cams, Performer intakes and stainless risers. my current Q-jets have been acting up lately and i was thinking about tossing these on. would they work on the small blocks?

TOO BIG You could but you will need to recalibrate them to run on your motors. Best off to just rebuild your q jets. They are cheap and easy to do Dave.

After you buy square to spredbore adapter, new hard fuel lines, and throttle linkage, you'll wish you spent the $40/kit on rebuilding the Qjets. Rebuild the Qjets.

thanks guys, i will re-build the Q's. actually i have had great luck with them in the past but was just wondering if i could use the webers, i will hang on to them for another project. the problem i am having with my current carbs is a when they are at mid throttle, just about when the secondaries are opening. i can run the boat at about 3 grand just fine. as i give it throttle my port motor gets a big stutter. if i dont back off or bring it up to about 4 grand or more the motor will actually stall. it runs great at full throttle or close to it ( which is where is usually is anyway )
