I recnetly purchased an 88 300ce that has been sitting for the past 3 years. There is a new radiator, fuel pump and it is up and running however, there seems to be a lot of smoke (white, smellstoxic)coming from the exhaust. I was told its due to heavy carbon build up in the engine due to it not running for a while. Can you confirm this? If so, is there an easy solution? Please advise.

Thanks,
88 300 CE
