1989 Ski Nautique Motor stumbling at 2200 rpms Printed From: CorrectCraftFan.com Category: General Correct Craft Discussion Forum Name: General Discussion Forum Discription: Anything Correct Craft URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=48080 Printed Date: March-06-2025 at 2:07pm Topic: 1989 Ski Nautique Motor stumbling at 2200 rpms Posted By: Guests Subject: 1989 Ski Nautique Motor stumbling at 2200 rpms Date Posted: September-24-2019 at 4:15pm I have a 1989 Ski Nautique with about 1900 hours on it.. This season it ran fine until about August 2019 when it started began stumbling upon acceleration at about 1800 rpms. The stumbling then resulted in spitting back through the carburetor. I have replaced the spark plugs,points,condenser, roter, and just rebuilt the Holley 4 barrel that it came with. I also replaced the double walled fuel line and fuel filter. It has improved slightly after the carburetor rebuild but still stumbles and I can nurse the speed up to 29 miles an hour. Moving the throttle to any faster position does nothing. 29 mph is the fastest it will go. Does anyone have ay ideas ?..John in Massachusetts...508-662 7576 Replies: Posted By: TRBenj Date Posted: September-24-2019 at 4:24pm Check choke setting/operation and verify timing setting (and confirm it’s advancing).
