Just finished replacing floats and float valves in an f2. Reinstalled the carbs and then the air box. That is when the trouble began. I have done this a number of times but this time I could not get the velocity stack rubbers to go over the carb intakes. They would either not go fully on or one end would pop off while I was trying to get the other to fully seat. I have never had so much trouble with this air box. I finally removed the velocity stacks and installed them without the box and then squeezed the box in behind and folded the stacks into the openings in the box. I still can't believe I had such difficulty doing something that I've done a dozen times before with nowhere near the amount of time, cursing, etc. I am wondering if I should consider something like pods, although I don't want to get into jetting and all that. Just wondering if anyone else has had a lot of trouble with one of these air boxes.
