hello bobby:
you give good advice as i already found out. yesterday afternoon i took off the after market fuel filter, which is less than a year old & looked at it more closely. it was very dirty, looks like rust sediment...... So i replaced that and bought an extra one to have on hand.....
than i went back to recheck the last tune up. i checked the timing and it was off. so i reset it. although i am curious to know why the timing was off........I pulled 1 pllug & it was black.
i took the car out for a drive after i tried to adjust the carb....
the car ran well. much better....
as far as the dirty fuel filter goes i think the last fill up ,( and i filled the tank full) prob loosened up all that debris etc. i never fill the tank , i just put in 5 gal here and there.

while doing all of this i uncoverd another problem:
several wks. ago i replaced the exhaust gasket where the flange is under the carb area. easy job . all went well. after, i checked and no popping noise and i could feel no air leaking out. YESTERDAY I NOTICED IT WAS LEAKING AGAIN.
when i installed the new gasket there was no sign of an old gasket. My quest. is what is the engine telling me.????
advice anyone????
as always thanks for all your help!
