I bought a new hemi headed predator about a year ago. Just wanting a little more power out of it. It's pretty much all stock except the block has been decked so piston is at zero when at top dead center, I milled the head .070
Engine runs very well like it is. I measured the throttle bore and its at .0750, I disassembled carb and ran a 47/64 drill through it followed by a .750 reamer. Doing this obviously busted through the thin wall casting of the carb body. I epoxied all the holes in and re-assembled carb and bolted back on engine. I'm trying to get the jetting dialed in at the moment. It doesn't want to idle for nothing even with the idle screw turned all the way in. Needing some ideas to try, thanks.
