2.25 swb 1973 petrol / lpg 2286cc engine with zenith carb.
Problem: starts/runs on lpg ok but can't get off full-choke on petrol or stalls. Once engine warm will run on petrol but stalls when I take foot off gas.
Tried/tested: carb dismantled and cleaned, petrol tank cleaned out, timing checked with strobe, points and plugs checked - but no joy. Was certain it would be carb but found it nice and clean. LPG conversion is most basic i.e pipe from mixer runs straight to air cleaner pipe.
I still think it must be carb but am at loss what I can do next.
Any advice greatly appreciated.
