Hi Guys,
I've rebuilt my Force 85hp (1989). Basically everything stripped down and put back together, including having #2 cylinder re-bored and replacing the piston and honing all cylinders. It's been a project and taken quite a while. I got to the position of turning her over for the first time today. The starter motor can't get her spinning, it tries and gets a short way and stops again - go, stop, go, stop - as if there was something sticking.
New starter motor and fully charged battery.
Tried direct connection from battery to starter to see if there may be a bad connection. Same problem.
There seems to be a lot of compression and takes quite an effort to turn her over using a wrench on the flywheel nut.
Removed the spark plugs and she spins over just great. Put in one plug and it turned over but a good bit slower, as I'd expect (with some compression being present). Tried 2 plugs and that resulted in the original problem re-occuring.
Anyone got any ideas/advice? Could I have done something wrong in the rebuild resulting in too much compression - I'm thinking exhaust ports or similar?
