I realize there is no substitute for a dyno when timing, but they are few and far between around here. Is there an "accepted" method for timing our G John Deere?

You can hook it up to a feed grinder and put it under a hard load and adjust it while it is running. Or, if your feeling real brave, you can have somebody drive it riding the brakes real hard while you walk beside it and adjust it.

Turn the dist. or mag.all the way forward and turn the flywheel till the impluse mark lines up with the mark on the transmison case.Turn dist or mag backward till it clicks are fires then tighten it down.

Use 730LP's method for a basic setting, then if you want to go for the "optimum", without a dyno or some heavy belt load, turn the mag/distibutor further back (counter-clockwise, advancing the spark) in very small increments of just a little bit like 2-3 degrees and with the engine pretty well warmed up, advance the throttle about half/2/3rds and try taking off briskly in 6th gear each time you advance the timing...she's sure to ping after about two or three advances...okay.....that's too far, back it down until no ping is heard.....or just the faintest hint of a ping...and try it that way for a while. If it does still ping under sudden load or any load, you should back the timing down some more. All this is for a warmed up high compression gas only engine...for the standard low compression engine, don't bother, just time it normally like 730-LP described. Whatever, don't run the engine if it's pinging for any time over a couple of seconds...it just ain't good for it.
