I have same set-up on my '35 with an 8BA and had the same problem. The corner of the carb adapter gasket some times brake off ( I assume a 4 barrel ) mine did as well but it's outside the seating area and remained sealed as I'll bet yours is. 30 degrees is too far advanced. If you can't find any timing marks on crank pulley or timing chain cover try this. Mark the distributor and engine with a reference mark before you start so you know where you started then retard till engine at idle gets rough and advance just enough to smooth out and go no further. That S/B close to where it needs to be. But you should have a timing mark on your bottom pulley and an arrow on the timing chain cover to use to see how far off you are. I would bet your off the gauge a lot in the advance direction.

Here's advice I got from Babba's Ignitions "These Mallorys typically are set up with way too much advance and the advance rates are incorrect for the flathead".

You'll get there as I did, Good Luck
