plug fouling
I have a 1972T coupe with Weber Carbs and I was wondering if I have options
I don't have a vacuum hose and I can't keep them adjusted and keep fuel fouling the plugs? this is strictly a daily driver and am looking for something that will start and won't give me the trouble that I am currently having |

proper plugs in correct heat range and an MSD helped solve my fouling problem.
It took a while to find the right plugs.

currently I am using Bosch super R6 585
I tried ACDelco R43XLS Champion 415 RN9YC My main cylinders to foul are 1 & 6 I am thinking maybe valve bushing wear but the machanic that works on my car thinks it is the Carbs since I don't have a vacuum line he had to advance the timing and that helped but after a short time the plugs foul and I have to change them out and then it runs great for a while (a week or two) when I cold start it it bucks and snorts and then begins to level out close to the end it backfires while driving, loss of cylinders and have to change out those 2 plugs?

my compression is good
my thinking is that if I was to try and find another engine and swap out I would be buying a whole new set of poblems I am not a mechanic and can only preform simple tasks tearing down the engine or even adjusting the carburetors is beyond my capability

That doesn't sound like a Bosch number I have ever seen!
Well, I suggest trying NGK BP6ES. Check your spark plug wires for end-to-end continuity ... 3000 Ohms to 4000 Ohms resistance. They can go 'open' inside the Beru connector and cause a fouling problem.
