well since i put on the new dizzy ive been messin with it to find the right spot. although it doesnt make sense to me that the dizzy only has maybe an inch of play but is that how the timing is adjusted? i just put it in a random spot but every once in a while ill get a popping like small backfire out the tail pipe when its revving down. wondered if this is the problem, i also have an error code 10 (faulty intake sensor) so my air/fuel isnt right. amazingly i still get 31 mpg but the power is ugly. anyway i dont have a timing light so any suggestions?
