it does'nt help to advance the timing at all now if it was on propane then it's best to advance it then you will notice big power gains but if you do that on a gas powered mill then your asking for trouble. if you want more power contact cliffords they got everything you need for your 6cly

Actually, to get the most power from your engine, the TIMING should be set as far advanced as possible, without detonation, using the fuel you wish to run in daily driving conditions. Case in point: At my last job, we had an old F-600 with a 370 gas job in it. Set to factory specs for timing, it was a dog. I finally got sick of the lack of power, and played with the timing. Got out the light, set it about 5* above spec. No detonation, more power. I went about another 5* above spec, still no detonation, and tons of power. At this point, we are talking about 15* at idle. This thing could actually keep up on the highway now, and it never detonated. On my 300-6 I get best power from 12* static, which is over 38* total at 3,000rpm. Any les, and I lose power, more causes detonation on 89 octane gasoline. So yes, having your timing advanced, within reason, does increase your power. But beyond that, if you choose not to use that extra power now on tap, you will get better fuel economy. That is why there is a vac advance on the dizzy.

the thing to remember here is that the timing rings on the crank balancers are rubber mounted, and tend to walk back and forth on the rubber ring-especially on motors that see severe duty, like that old 600. the mark(s) on the ring are a good starting point, but always time for power by the seat of your pants. unless of course the balancer is really wasted/turned too far, in which case you,ll get grey hair trying to figure out why the #$%^ pig wont start and run on 'tdc'. an old racers tip is: once you verify that your harmonic balancer/timing ring is ok, paint a line on the front of it, across both the center and the ring. that way, you can tell at a glance if its walked around.
