I have a 1987 mariner 150 serial 0b117356, manual says there aren't any screws to adjust air/fuel, simply idle air bleeds, however I do have screws to adjust, what would be a good starting point, (how many turns from lightly seated.)
You shouldn't if they are correct for the year WH carbs . . What carbs do you have? Theres letters cast into the top i.e. WMV or WMH and numbers stamped on the side flange.
After looking at a few parts warehouses I noted my carb WH-33, which is correct for my year and serial number however they all were non adjustable jets. Do you suppose someone changed from fixed to adjustable? should I change back? I also noticed when I lightly seated one it didn't make any difference.
Those are right, WH series use an "idle circuit only",adjusted only with a jet change. "Screws" came out with tha WMH series on tha V6 in '90......Uses a different linkage and throttle cam also..........jan. if its had a power head change serial no. on tha clamp bracket isn't any good.
Thanks for taking the time, I'm a bit confused as to what I should do, sounds like someone put the wrong parts in, should I change back to the fixed jets?
Your pics arent working. Mat want to post a link to an external picture hosting site. iboats is having problems these days. Must have gotten a good deal from the government on used websites.
