Ian,

If the carb is too big for the engine, and is set up improperly, you could wash the cylinder walls down with fuel causing premature wear of the engine as the gas mixes and thins out the oil lubricating the engine. First thing you want to do is pull the oil level dipstick and check for a raw fuel smell on it, if it's there, and it's heavy, then walk away from the car as the oil is most certainly contaminated, for how long is anyones guess. As for those members on a "cobra forum" making you worry, hogwash......Stop over at this sites sister site http://www.clubcobra.com and you will see the difference in actual knowledge vs the ukcobraclub.com web site..............Again, not putting anyone down, just giving you the very basics you need to assist you.
