Carb. Jet size

[Jonfuss]

Look to upgrade to a 200hp from a 135. I have WMV 3 carbs can I just change the jets and be good or do I have to get all new carbs?

I found a lot if really good info on this site when I was looking to upgrade my 150 carbs. I've attached a link that has some good reading.

There is a lot more in bumping horsepower from 135 to 200 than just carburetors. Often the bore size, definitely the porting map and configurations in the cylinder walls. Plus the carburetors. Everything adds up. Certainly not just a carburetor swap.
