71 Duster 360 turbo build
I’ve been sorting out all the new editions and the car is running great…out of boost. The carb is going lean and I’m running out of ideas. Initially it was doing okay running it exactly how it was last year with no PV and 86 jets front, 96 rear. Was still going a little lean(12.5) up top so I decided to try out a front pv to add some fuel. After tossing in a 6.5 pv with no other changes the carb has done nothing but go 14:1+ under boost. The power valve didn’t seem to be opening. Pulled the carb hat off and drove na; pig rich sub 10:1. Pv definitely opening when the hat is off. Put the pv plug back with the same jets as before and still 14:1+. Verified fuel pressure is rising 1:1 with boost, and triple checked float levels. Whatever changed during that power valve install I do not know, but I guess I’ll have to pull apart and clean the entire thing.
Besides that I did some low effort paint so that I would qualify for vastly cheaper antique insurance.
