Hi everyone,
I have a 2000 model mercury 75hp carb motor that runs kind of rough sometimes. Seems to be getting a little worse.
I cleaned the carbs out really well last season and it ran fine, not as smooth as I would like, but fine. This year it seems to be getting back to its same old ways, even though I have 2 fuel filters on the boat. I also didnt let it sit all winter, we would take it out occasionally to keep fresh gas running through it. I also had my vacuum tester on the carbs and synced them up.
Anyways, I keep reading that you can swap out the jets in these engines and it will run smoother. Something like the small jets that they put in these engines were meant to meet EPA standards, but clog up very easy and make the engine run crappy.
Does anyone know what carb jets I need to switch to. I cannot seem to find any info on what jets I need, or where to buy them. If someone can help me out with the source, im sure I can get this engine running fine.
I also recently changed out all the spark plugs. Also, the tach goes a little crazy on occasion, IDK if that is part of the underlying issue also.
Any help is much appreciated.
