>>The Shell Petroleum website (www.shell.com.au
) states that no pre-1976 Mercedes can run on unleaded petrol. Furthermore, if a car uses their Optimax fuel, and it doesn't have hardened valve seats one application of their 'Valvemaster' product is required per tank of petrol.
Hmmm that's news to me?..I would rather trust a source from Mercedes as obviously Shell wants to sell their products. I dunno?
Can anybody else confirm this?
>>>But, have you (or anyone out there) had experience in using the JC Whitney Carburetor Synchronizer (SKU 88ZX2792N) - this is the direct reading, dial type one on their web site?
The unit appears to have a rubber skirt and fits a variety of carby shapes.
I have two of these and they are good but you also need the hood adapter and offhand I can't remember where I got that but it wasn't from Whitney.
