chattering sound

[EJ]

Here in the UK I have the same problem, engine like a sawing machine and all that, so the other day I tried a better grade of fuel and the chattering has gone a bit quieter I just hope my tiny mine isn't playing tricks so now I'm going to try good grade fuel and an additive, have looked at all the other ideas you guys have come up with keep them coming.

As I recall it is copper side out. Do you recommend the two piece gasket or the one? Please correct me where I'm wrong. Jack

Are you adding about 4 ounces of Marvel Mystery Oil to a tank of gas? May quite things a bit. Chap

I had a ticking noise that ticked 2 times each revolution with the crank. Turned out to be play in a two piece cam gear. Look in the side cover for the cam gear that is aluminum in the center. The gear should be all aluminum or all fiber.

I'm using Redex Lead replacement 250ml bottle enough for 4 full tanks of gas. I have put the first lot in but as we speak I have not used the car yet.
