I'd try setting the initial timing at 10 or 12 BTDC. If you have a worn timing chain and distributor drive gear or out of place timing marks, that may get it closer to correct. If it kicks against the starter when warm, back off just a little. I've had very good results using Marvel Mystery Oil in older engines with gummy lifters. A good 10W30 detergent oil is beneficial, also.
