1989 200 Black Max High Altitude

[jscgdunn@telus.net]

HI Everyone,
I have a 1989 200 BM and have installed WH22 "drag" carbs. I purchased them from a racer in Florida. I bolted them on and the engine runs great. I am concerned about the jetting, however, as I am often operating at 3500 feet+.

Could someone reccomend the proper jetting?

Thanks and Regards,


Jeff

Here is the jet charts... If you look on page 2, you will see a chart on how much to change the jet size from "standard" jetting. Hope this helps.:thumbsup:

This is more of a redirect, was wondering if the jet sheet will also apply to a 1989 150XR4? would be nice if it did.

Thanks

Are you running at 3500 all the time or just once in a while? If it's just once in a while you can simulate jet changes sorta by using a lower octane fuel and dropping down an inch or two in prop pitch. I fish at 5800 ft a couple of times a year and that's what I do.
