Re: Carb rebuild mistakes on 1984 100 HP (typical v4 crossflow)
Hard to know exactly what you are driving at from your comment. Would be helpful to know what symptoms you are experiencing. It's unusual to need to replace the jets in a carb unless a prior owner had drilled them out. I take it that you checked the factory parts list and replaced the jets with those originally recommended by the factory. (assuming that no modifications were done to the engine, such as composite reeds or high compression heads.) If the engine has been sitting for some time, it is possible that some of the fuel has dried up inside the carb body. This is hard to detect and hard to get rid of when overhauling them for the first time. You need to clean the passages with a product which will dissolved dried fuel. Like a Gumout type product. (An aerosol version works well.) When cleaning, it is difficult to know exactly when those passages are clear unless you spray something thru each passage and compare the exiting spray flow from one passage from one carb with that same passage with another carb. When reassembling the carbs onto the engine, there is a specific "sync and link" procedure that needs to be followed to sync both carbs with each other, then with the timing advance arm on the timer base. An original factory manual is helpful here.
