Update, no way I can get the bowls to seat with those seals, I tried 3 in 1 oil, grease, dish soap, I tried putting the seals on the tube first and pushing in the bowls, then I tried pushing the seals in the bowls first and trying to insert the tube, there is literally a good 1/2 inch of space to cinch up and I'm afraid the fragile aluminum tube will bend, I tried pushing on the carb with my body weight against the carb and the workbench, I actually thought of using a cargo strap to ratchet the bowl to the carb, there is NO way it should be that hard so I just went back to the o- rings, ( new ones ) and it just slipped together. Weird but anyway it's back together, I went through it all again I'll either throw it back on in the spring or I might try it in the next few weeks and just find a nice day to run and tune it, if it don't work I'm done with Holleys and I'll stick with Edelbrock.
