looper timing
I have 1988 225 rude looper. Any way to set timing without a loadwheel in a tank or on the water at 4500 rpm with any accuracy. People talk about securing to dock and letting it rip, but I don't know about that. Any suggestions? I don't want to run it hard, unless the timing is right.

Re: looper timing
you can get it close by puting it full throttle holding the timer base full stop maybe need to wire it full open on some crank it and test with a timing light should mark fly wheel 4 degrees less so if your looper calls for 18 degrees mark it for 14 cause with it running it will advance 4 degrees should get you close also its a good idea to index the fly wheel for the rest of cylinders and check those as well each tooth is 3degrees on 120tooth flywheel good luck phil

Re: looper timing
To index the other cylinders. do you mark their TDC on the flywheel, and then mark off appropriate number of teeth for proper timing?

Re: looper timing
Thanks for the help dehydrated. I advanced timing all the way out, but left the throttle closed. Will that work as well. I reset timing 4 degrees off spec.

Re: looper timing
