When you turn the eccentric shaft,and the rotor is right next to the two sparkplug holeswith a flat side,then your at TDC.Remeber that open BTDC (before top dead centre)
Its allways interesting to see what port timing different people are running...mine is 340 deg

ok i found tdc found my intake to open at 32 degrees but then when i look for it to close at 50 degrees i see that it's still open.. or is there a mathematical equation for this ??? or am i just not seeing this.... i no the 1/3 ratio between the ecc. and the rotors. and the 270 +the 90. i'm still not getting it..
yes my ports are still stock 87TII.. the other thing is what do you guy's think would be a respectable timing for a 35 mm pport with the side race ports still open... i want the least over lap as possible, yes i do plan on timing for it.. but i still got to fig ure this boner out..... if any one can help thanks.. jody hammock

i have it printed out and sitting infront of my engine. it's like i'm just missing somthing very fundamental.. i keep coming up with like a 60^ IC and i don't get the correct exhaust timing that the fsm says i should... well i'm going to go over there in a couple and hash it out and see if it slaps me in the face... somthings not right... did you guy's have any probs...
