Man do I need help, dual webbers Options

[dlindzey]

Short story is I am an idiot and did not ask enough questions about the rebuilt 1971 914 that I purchased. It has never run just right. Biggest issue is a slight bog down at 3000rpms.
Allegedly it was rebuilt with a kit and had the cam changed for the dual webbers. It has had a fuel pump put in by me via reputable shop.

I have taken it to a new shop and was told it had webber 44s and not the correct 40s. I asked if they could modiffy the 44s to work (says it be done on line) and they said no, it needs new 40s. They also said compression is only 100psi in each cylinder but equal through the 4. I bring this up to see if doing anything is even reasonable. So all of this undocumented-kit, cam and just told to me by prior owner. The rebuild shop is out of business.

so what would everyone do here, push for another shop to modify the 44s or go along with the 40s or just change the oil and live with it as a daily driver until the end?
