Carburetion-exhaust

Anyone who had followed my tale of frustration about super rich and back firing carbs etc, the whole deal has been ironed out.
The car originally had a 2180, albeit one of those weak JCX junkers. It had the big Dells but a small 1 3/8 Bugpack exhaust.
WHen I had a built a 1776 motor installed it ran way to rich---so dark that the plugs were almost black.
Now with the 1 1/2 inch dual exhaust system on, I took the car on a long 250 mile trip. Once back I checked the plugs. They are a nice gray (brown maybe) and even all around. Eddie's mantra to me---"One thing at a time" was absolutely right.

Congrats!! Nice to see someone work out a problem satisfactorily!!

Pretty amazing how much the size (and flow) of the exhaust affects the induction and fuel-burning end as well, huh?

Yes, GOrdon. I was amazed how all that stuff, back pressure, flow, pipe diameter, carburetion all works together.
I have a friend who has one of those 200mph Miatas---dynoed at 300 hp with Supercharger etc. Needs a laptop to tweak it. Maybe one day I will want to go there with mass air flow meters etc etc but I guess i am comfortable with techology that I grew up with. Even tho I have been tweaking points,, carbs exhaust etc I still learn something new, but at least I am not starting all over. I am trying to learn some new software and after 10 years on a diffent system I feel like I can really identify with a friend who had a stroke. He would read, understand and then the next day have to start all over. And I so not yet consider myself a geezer, lol or Old F.
So now that it is all together and runs great, what so I do now?

DRIVE IT!

Great idea. I did that. The weather here int he great North Wet has been positively topical with Sat predicted to be 75. Since we get some 70 or so humiddity it is perfect top down driving. Next Weekend the PCA group is going for a run and that is always more fun than just driving solo.
