Considering a newly overhauled carb that will also give me a bit more fuel flow - looking at the 10-3678-32 MA-4SPA. ACS has both Avstar units and MS units, with the Avstar being about $300 cheaper. Anybody have any experience with switching - are they identical replacements or might I run into any issues? Any feedback in general on the difference between the two? Thanks!
