    AQ131A Carb idle screw Missing

    Hello, I inherited a 19ft citation 1900 cc with a Volvo Penta AQ131A in it. The carb was taken apart years ago and somewhere along the line the mixture screw went missing. This is the single solex downdraft PA44 setup. Most rebuild kits come with one of the two mixture screws and unfortunately i...

    Wacky tach readings

    I’ve got a tachometer issue. As long as I’ve had the boat the tach has never really worked. When running it would stay at about 900 rpm and randomly jump to 4K and stay there regardless of true engine speed. I assumed it was an issue with the tach itself so I replaced it earlier this week.

    No aftermarket for EMM?

    I've got a 2004 Kawasaki ultra 130 di with a bad EMm and I'm wondering why there is no aftermarket solution to the $1300 dealer part. Since it's commonly pinned as the #1 failure with these skis I would have thought there would be an aftermarket solution. I know you have the option to have it...

    Collapsed lifter or wiped cam lobe?

    Finally got the engine together and ran it for the first time. It ran rough but as the engine warmed it will smooth out. Went to adjust the rockers (I like to do a final adjustment check while running) and found one of my intake valves barely moving. I pulled the rocker back off and can move the...

    Mercruiser 3.0 lx throttle linkage

    Hello! Recently bought a 1996 hurricane deck boat with a mercruiser 3.0 lx that had been taken apart by a previous owner and kept in boxes. I have the engine back together but I am having issues figuring out how the throttle cable attaches. I can attach it to the carb but I can't figure out...
