I have been chasing a nasty vacuum leak for weeks in my 1969 GT 1.9L with Weber 32/36. I have done the usual stuff (replace manifold gasket, carb gasket, pull carb, rebuild carb, replace) but no luck solving it. Hopefully this is a new facet to an old question: when I spray carb cleaner it at carb base and intake manifold it will actually slow the engine if not outright stall it. I suppose this is essentially flooding the engine instead of making it race, but the end result is that it is indicating the same, major leaks everywhere.
Could carb cleaner stalling the engine be indicative of anything else, the reason I ask is that all my repairs seem to have yielded absolutely no progress on the leak. I am a hack mechanic, but still I thought I would see a little progress swapping out the old gaskets and rebuilding the carb.
Thanks in advance.
