Hey guys:

I"m working on a Oliver 77 gas and have an I&T manual but it does not show how to adjust the valves. I have the firing order and the gaps but not the sequence. With the #1 cylinder on TDC, what all valves can I adjust and what do i have to do to get the rest done. Anyone have pics or a piece that can be copied out of an original Oliver manual?

Thanks

HAve you ever used the valve overlap method? Do you have a piece of chalk?

Put #1 TDC compression stoke. To do that I would watch the valves on #6. When the exhaust valve close the intake will be opening. Stop at that point you will be real close to #1 TDC compression stroke. Put your mark on the front pulley. Turn it in direction of rotation and watch #2. After a 120 degrees of rotation the same thing should be happening on #2 cylinder. Set the valves on #5. Put a different mark on your pulley and turn again 120 degrees and watch the valves on #4 and set the valves on #3. You have done this in one turn of the crank. Now as you turn 120 agrees again watch #1 set number 6. You should be where you made the first mark on the pulley, then turn again watch #5 set, 2 then go to the next mark watch #3 and set # 4. The one you want to set and the cylinder you watch add up to one more than the number of cylinders in the engine. Clear as dirty mud? Good luck? Questions?
