Timing a stock GT

Thanks for the advice all ! I plan to clean and paint the balancer and gauge flat black and use the white out to mark the 12 degree and yellow to mark 14 -

I got around to changing the fuel filter. Car seems to idle much more smoothly , the irregular light choppy feel is gone . Gas in old filter was dirty with a high amount of visual black specks ( like a fine ground pepper ) . Maybe the old filter was restricting flow and causing the chop and furthermore causing AF mix to run lean ( would that cause engine temps to run hotter ? ) also , what are the options to clean out tank ? Does it have any drain Valve ? Btw , car has been running 180-200 degrees over the winter and in this early spring outdoor temps of 65 degrees in Wash DC area .

How much work involved taking tank out ? Unknown age of pump ( will change that though since tank is down ) do we just replace tanks or is there a method to clean them out once down ? Btw does the A/F mix theory on engine heat sound possible ?

Yep - stock radiator , new HD fan clutch - prob 180 degree stat ( seems to open there )

This was last summer btw - 95 degree temps - yes shroud , no ac , driving on highway -

Btw General - we talked about this in depth on another thread - in a few weeks I will run just water to see temps . Then change radiator if needed
