Need advice helping a buddy set the magneto timing on his �new� Oliver 70. (Manuals are on order but are a couple weeks away�) Here�s what we have:On the flywheel there are (3) marks: IGN-OIL, IGN-GAS and TC-EXH. On the mag (American Bosch) there�s what I presume is to be a timing mark visible thru the small window near the bottom of the cap (a white line on the rotor gear). The #1 nipple on the mag cap is clearly marked and the plug wires are properly connected (1-5-3-6-2-4) in the direction of rotor rotation. The mag is hot and the impulse snaps nicely every 120 deg of crank revolution. Using the �thumb in the spark plug hole� to find the compression stroke on #1, have tried setting the mag so the impulse snaps at each of the 3 marks on the flywheel (i.e. when each mark aligns with the �V� notch in the inspection opening.) Timing was verified using a timing light hooked to #1 and cranking the engine. However the engine will only pop out of the carb and exhaust at each possible timing setting - it will not fire and run. It has good compression on all 6 cylinders. The carb appears to be OK (not flooding and it is feeding gas). Plugs and ignition wires (solid copper) are new. Shutting off the gas and giving it a whiff of ether thru the carb still only gets us popping so it�s not a flooding or fuel starvation problem. Even pulling the tractor (so the crank is spins 600+ RPM) gets us only popping. It apparently is firing on all cylinders as all 6 plugs became quite warm after pulling for a minute or two. Appears as though the timing way off. Is there another timing mark we should be using, are we timing to the wrong cylinder, or are we doing something else wrong here?? Any help is appreciated! �.Bob M
