running rich
Took her out yesterday for the 1st time in months except for running it through 1st and reverse at the garage. Noticed back at the garage that it there was carbon inside the tail pipes.Pulled the plugs, all look to be running clean except for some carbon on the back of the curved bit of 2 plugs (sure it has a proper name). Cleaned out the air filter and it's drying. Haven't started her today as it's my birthday and had to get back for lunch. Anything else i should take a look at? Thanks for your help. 340 small block.
Re: running rich
BTW, what are the plug gaps on a 340?
Re: running rich
I'm no expert at all and I'm sure the guys with tons of knowledge will be along soon but my first thoughts are to ask if the car was running ok and clean when you parked her up and were using her more? I doubt if anything has changed since you parked her up. I know the lockdown rules are in place at the moment. As soon as they are lifted, I would take her for a good run and see how things look after that. Just starting a car up and running it on idle on the driveway etc wont give you a good indication of what's going on.
If anything needs to be adjusted I would imagine it would be either timing, a stuck auto choke (if you have one) .or your idle mixture maybe. If you have an Edelbrock carb, easy check is to see if the metering rods are stuck. That can make the car run rich as I did with mine a few years ago.
Just a few very basic thoughts
Cheers Steve

Re: running rich
Forgot to say, I believe .035" plug gap is a pretty safe starting point on most Mopars that are stock or mildly tuned. Quick check online will tell you for sure

Re: running rich
And sorry, re read, you did go for a run....doh. I would do a check on your timing, idle mix etc just as a starting point to rule things out if nothing else

Re: running rich
Thanks Steve, will have a go on Wednesday, are you the guy relocating to Scotland? My old school mate moved to Inverness in the 90s. Loves it. Gerry
Re: running rich
Yes Gerry, I've moved to the Scottish Riviera as they call it.

Re: running rich
Problem solved, put new air filter in and running fine now, so don't think it was old fuel but may have been a factor.
Re: running rich
Thanks Steve, where are you in bonnie Scotland?
