Any Weber guys here?

I have a 48DCO in the REPU. In my experience if the floats are set too high you get fuel dripping inside the throttle bodies. Just look in there and you can see some dripping going on. It will even flow back out the intake side and drip on the motor. Too low and you will run out of fuel quickly on a full throttle run.

The first thing I would do is stick a wide band in there if you dont have one already. I had the REPU running somewhat OK for 5 years, but with my recent rebuild I installed a wide band and in about 15 minutes of jetting I have it running way better than it ever did in all the time I owned it before! Its really quite a chore to get things right without one, and I suggest you have it tuned perfectly before you even start working on your blow through setup.

Dont make a decision based on how clean the carb is. These can be completely torn down, cleaned and rebuilt in an hour.
