I have a stock predator hemi that I have installed an electric start, stage 1 filter and jet from GPS and a 1 inch exhaust with a silencer on it. So far I had the stock carb with the larger jet on it and it runs and starts ok, but since the stock carb doesnt have a fuel mix screw, I bought a $15 replacement off of Amazon to get some adjustment to get it to work a little better. With the Amazon carb and the jet it came with it barely ran or idled when I put the big jet in it the thing ran poorly and smoked like it was too rich. So I put the stock carb with the big jet back in and its back as it was before, but I want it to start better and idle better.
So I purchased a TFB carb and got a chance to get it installed today. It wont even start now. After reading about it a little bit I learned it has an accelerator pump that squirts some fuel in it. With that knowledge I tried again by twisting the throttle body 10-15 times and it starts and turns over 3-5 times and dies. So it seems like its just not getting fuel. Does this carb need a pulse pump to operate correctly? Is there something else I need to do with this to make it operate?
