Help needed with sb 318
This carb photo is of the left side......as for legs on the manifold......I assume you mean exhaust......it has 6.
Again, sometime in the recent past (probably 5 years ago), previous owner replaced original 1969 -1970 era 318 with newer 1983 engine....as per date stamp. No VIN, so probably a generic replacement engine.....and probably used at that. Belief is that for the engine swap, they kept most of the old original stuff like the old carb, etc, and installed those on the newer engine block.
Engine starts easy enough (considering it does not have a working choke), idles well, runs ok at speed....say when cruising downhill or on a flat surface......but stalls under any sudden load....say if you rev it at idle.....any load....like going from cruising downhill to uphill....letting out the clutch from a dead stop, etc. It will pull itself up a hill, but only if you are geared way down and revved up to 3,000 rpm +.
