I recently removed and cleaned all four carburetors to adress lack of idle. Upon reinstallation i noticed the engine was giving off a sputter like backfire that sounds like a compression release. I've removed each plug to test individual cylinders and noticed it sputtered less when cylinder 2 was removed. I did not rebuild the carburators and feel like the problem may be either too much air or bad fuel although the fuel appears to be fine. If anyone has experienced anything similar i would greatly appreciate your knowledge.
