mechanic is saying that he needs to remove carbs to investigate/fix backfire issue (bad). He believes carb(s) are dumping fuel which is cause of the problem- maybe float stuck or something? There is a heavy fuel smell after running the car...heavy! How many labor hours should I expect for removal, tear down and rebuild of carbs?

If you are getting loud backfires, you have an exhaust leak for sure.
figuring out if the pops are coming from the carbs or the tail pipe can be a challenge, but a backfire is a sure sign that it is coming from the tail pipe. have the car smoked and see if they can locate the leak. Any exhaust shop can do it. They put a smoke machine on the tail pipe and look for smoke coming out of your pipes. if there isn't any, your exhaust is sealed. but if you are getting loud bangs, no way are you sealed. If the pops are coming from the carb, that means you are running a little lean, or are out of balance. Once you have eliminated the exhaust leaking, then move to the carbs. and read the weber tech book. So much good info in there. Zach |
