Dont laugh at me!!! with my rookie tuning :(

Ok !!! So my car was running crappy for a couple of days and the performance got worst and worst ,

1- i thought it was the timing because the car was becoming "shaky" at low speeds / idle , i pulled off some timing and it helped a bit.. for some time.

2- i had a sudden stalling problem..changed the relay / am meter bypass / fixed the fused link... still the car didnt run right ,

3- i thought it was maybe my points ..redid the points ( new set ) gap at 16' , at the cam and lubbed up.. didnt changed much , after that i was f*ck it i tought i was Jake King and said ill fix the timing myself...never good at that , but i wanted to try , brought the damper at 0 tdc , distributor seemed off pointing in the middle of the engine , did another rotation and it was pointing the firewall , so i was like..okay , i took a magnet, too the gear and turned several times , but the best i could do was to have the rotor pointing at cyl # 3 , piston #1 was up and valves seemed to be close...i think...tried to start it several times...didnt wanna go , reajusted the points....and BANG...right muffler exploded...i think it was enough for today , but im very sad and frustrated about the timing thing , i have hard time understanding it correctly ( to do it the proper way ) i cant really do it by ears...i bought at regular timing light..but im all confused now , with a car that doesnt start and was knocking / pinping and shaking like crazy...was running very good 4 weeks ago and now its broken , just standing there in front of my place , i really wanted to practice and do it by myself but it backfired at me , in everyway !
