Hello all, I have a 70 std beetle with a 74 (fuel injected) style block in it. it has always had a slight tick to it. but recently started runing bad i.e. dying everytime i try to come to a stop. and sputtering and back firing when i try to take off. and the ticking has recently gotten louder. noticed the electric valve on the carb wasn't working. so i replaced it. didn't fix the problem. tried changing the oil and adjusting the valves. didn't fix the problem. tried converting the points to one of those magnetic pick up disc type ignitions. didn't fix the problem. i am kinda at the end of my rope. any help would greatly be appreciated.
