1971 MGB, has Weber 32/36 DGV carb, I put a "rebuild kit" in it. Had some varnish in the bowl, I took out and cleaned and/or checked for blockages. Engine had problem before rebuild, would only run @ 2500 RPM, with Manual-Choke plates almost closed, 1/8" opening.
After rebuild installed, will start easily with Full Manual choke, and can be reduced to about 1500 RPM, (a little rough) still with Choke plates @ 1/8" What is going-on here?
