Thinking about taking a late model 051av and going to 076av super. I’m not concerned with differences between ignition, chain stop, fuel tank, manual oiler, etc. I think I have a decent grasp as to what needs to be done, and have sourced all the parts necessary to go to 075/076 but the additional spacer on top of the manifold that is unique to the super is nowhere to be found so far. Has anyone here every taken the manifold off of the 051, which I will have left over, and fabricated the 1/2” spacer needed to make the super? Looks like it might be as simple as chopping off a 1/2” and maybe opening up at most, but I don’t have them side by side yet, and of course I don’t have the original 076super spacer to compare them all. Also, anyone with a super out there, is there an additional gasket between the filter housing and the air filter? I’ve only got the 076av IPL that has the multiple air filter schematics to go off of, and was wondering if part 1111-149-1200 is a 076super part. I can find an even pic of it on the internet. In the IPL, it looks like a metal or plastic part, not a gasket, but what do I know. I’m new to this and just spitballing right now. Thanks
