Great starting became hard starting.

Car starts great again. I think it starts better when warm than it did before. I think I fixed dieseling problem. I gave it more timing 20. That brought idle up so I can reduce idle screw. Then I rechecked air screws and one was way out. Like 3 or 4 turns. Not sure how that happened . Put back to 1.5 out. Adjusted for max vacuum. Was able to reduce idle some more. Took for a drive and ran well. Also seemed to run a little cooler with more timing. Now to try to cool fuel line. I am getting boil in filter.
