dead spot in carb

[swampy2646]

hi, my 5.7 T/I 4 barrel rochester mechanical, has been running great since my fuel pressure and electrical problems. i used the boat 2x last week and she ran great. yesterday when i accelerated to about 3300 all was well , but anything after that ( i'm assuming secdondaries) the engine wanted to stall unless i brought back the throttle. i changed the water sep, just a spot of water in it. any ideas?

Sounds like your mains may be plugged at least partially.

Secondaries may be opening too much. When it starts to bog, have someone slightly close the upper secondary plates.
