1991 Fastrike 150 hp had the carbs cleaned and rebuilt with all new gaskets and now after we put them back on she won't idle.if you spray a mix of gas and oil in the throat of the starboard side she will stay running ,spray into port side and she stalls.it seems to be only the starboard side that has a problem what do I look for now ???? even replaced manifold gasket yesterday still the same

that's why we originally cleaned and rebuilt them because it was stalling when putting it on the trailer or when she was trimmed real high and going slow they look correct

Does it run 'above' idle speed?

Pull a float bowl drain to verify fuel in the carbs, it is possible to have a bad fuel line and NO fuel on that side.

Otherwise, suspect clogged idle fuel jets or air bleeds still. Did you blow out ALL carb passages with compressed air?

Do you have the FACTORY Service Manual?

Restart at square one, sync the carb linkages and link to the timing advance per the OEM directions.

If the throttle linkage is off, that whole side could be lagging so badly that your addition of fuel perks it up and makes it 'seem' as tho it was not firing.
