89 Johnson 110 carb jets

[waschu2]

HI, I am installing a rebuilt power head on my 110. The instructions tell me to enlarge the carb jets .002 inches. Can I buy oversize jets or drill mine? Does anyone know what the stock diameter is if I have to drill mine oversize. Also, who has the best price for a new VRO pump? I am running out of money but, I need to replace my 18 year old pump or premix. My Ranger has a built in tank that makes premix a hassle so I would prefer a new pump.
Thanks

Re: 89 Johnson 110 carb jets

Your engine uses 67C jets, part number 317183. Many of the service manuals from this vintage have a master list all of the jet sizes. You should be able to ask the dealer to look up the list and get larger jets. I would not drill out the jets. They are specially made to flow an exact amount of fuel and drilling them larger may not work as well as a new jet.
