4ac timing help

I just bought an 84 Corolla SR5 rear wheel drive 4ac weber 32/36 carb and I'm having a problem with the timing if I line up crank and cam pulleys on the timing marks perfect then put mechanical timing at noon or facing 1 on cap won't start only way I can get it to start is by putting rotor facing the 4ac on the valve cover and then the timing is at least 40 out any suggestions?

I assume it runs poorly or at a fast idle? From what I'm reading out of this post is that you are some what mechanically inclined and you decided to change your distributor because of a no start condition?

With that being said, I believe you have the distributor in there correctly! It sounds like you have the cam off 1 to 2 teeth! The number 1 tower on the cap points at the 4a-c on the valve cover! But with the timing light being off 30 plus degrees (ignition timing being 4-10) I would bet money your timing belt is off just a touch.....

Maybe post a couple pics of your situation and maybe one of us can photo shop something for you!
