      The cork method for finding TDC was remove plug #1 lightly put a cork in the hole ( tie a string to it to make it easy to find) use a remote start switch to bump the starter until when the cork pops out--explosively check for the...

      FINALLY! It's in and pumping oil. There were two simple problems... when I pulled the dizzy to change the Eigniton the upper O-ring ripped. I replaced it, but apparently it was just a bit too large. to compound the problem, one part of the...

      that's what I did. It starts up just fine and runs, but still no oil pressure...though there was with the drill. Seems like the dizzy isn't all the way in, but it felt like it dropped and there's no shoulder left at the block. I'll remove the...

      Pighead, you said "line up the gears" when you stand on the tire and push down on the dizzy and then bump the starter. Could I be not lining up the gears somehow? The FSM suggests lining up the pump notch with roughly the #4 plug...

      right now I'm just trying to get oil pressure. When I spun the pump with the drill my observer said there was pressure on the gauge. Set the TDC with a cork-pop-out method, check for true TDC, position the dizzy, then use downward HARD pressure...

      Thanks! That eases my mind, and now I'll try the drill...

      thanks for the description of the pump action. I was using a long screwdriver in a drill to try to turn the pump. I was hesitant to spin it too fast and too long....any advice on that?

      question on the oil pump cam... - should it be spinning when the engine turns over? I used a remote start and didn't see it move at all... -When I turned it by hand using a long screwdriver there was some resistance or drag, it wasn't 'loose'

      repeated the dizzy install, fired it up and got 50 lbs oil pressure. Shut it down to clean up a bit. When I fired it up again, no pressure! That dizzy sure looks all the way in...

      yes, I understand the 4 cycle, 2 TDC. I used the cork method to find the compression cycle. Repeatedly. It fires up and runs pretty well, might need some fine tuning. But... Of course now the oil isn't flowing to the rockers. Tried repeated...

      Thanks for the help!! I would claim a "senior moment", but brain death is more apt.

      WOW! The 'stick method' I used pulls the #1 plug and puts a long dowel into the cylinder to 'feel' the piston rise. It just determines that the piston IS at TDC, the compression stroke when the BB is visible. I don't see how it could be anything...

      fcgadget replied to the thread timing and backfire.
      I get the 2 rotations and the 180 my confusion is.... TDC is when the #1 piston is at the highest point and the BB is visible. If the piston is not at the highest and the BB is visible then it's 180 from TDC. I know I could check the valves...

      Pighead, ya lost me. I know I'm tired but what exactly do you mean? I know I'm not 180 0ff,

      forgot to say.. the BB is on the point on the flywheel

      '71 FJ40, '74 2F engine, Fireball ignition It WAS running, but needed to replace the fireball ignition Noticed a missing upper O ring on the dizzy replaced, but it wouldn't let the dizzy drop down...O ring too big....replaced with a better fit...
