I've gone through 2 Engines in my 96 spx, I've tore them down well and they run well when everything is put together properly and is well lubricated lol. These are solid engines, they produce alot of good low-end torque, and without rave valves or counterbalance shafts they are really simple to rebuild.

I would agree. If I had started with a 951 I doubt I would have attempted to build another engine.

@@SeadooRefurb Yeah, I kept having rotten luck with my ski I got from my uncle who passed away last year, got it from him in 2016, needed everything. All of the electronics were fried, engine was toast, pump needed rebuilt, etc. rebuilt everything but learned the hard way that aftermarket replacement parts are a waste of money as they don't last, stuff breaks, and then your stuck up on the river and broke in more ways than one. Once I kept looking through the shop manual countless times, I learned more and more each time I looked through it about my ski. I've also learned with engines and anything on these old skis that you need to do the job 100% and buy all new fasteners. I've wasted alot of money on things that were completely preventable but were a good learning experience for me.

In the 45th minute when you put the small o-rings for the spark plug areas, I noticed that you didn't install the o-ring (manufacturer P/N 420831550) that goes around the perimeter of the head as is shown in the shop manual between the head and the head cover. I ask because my didn't have one when I pulled it apart. Should it be installed? I noticed on one of the parts site that it says that it's been discontinued by the manufacturer.

Matt - your video gave me the confidence to rebuild my 2001 GTI 717 engine b/c one of the rods was busted. Had your video playing as I did each step. I got it all back together and it fires up and runs but I have 2 small issues. A - from cold I can only get it to initially fire up with a squirt of gas in the carbs. After its fine and restarts fine. B - a compression test only shows about 90 psi in each cylinder. New pistons new rings all new gaskets etc. Any thoughts on these? Appreciate you time!
