Plug all the ones you plan on not using.

What are adapter plates, and where do I find them? I'm a bit of a noob at this. I have plugged all the unused hoses, I set timing, set idle, its at about 1000... It will stay running but it kind of has a rough idle, its poppy sounding.

The adapter plates are underneath the carb. You will have two of them between the carb and intake

I don't feel like working on anything at this time so i sold my yj.

That is if he has a webber. Webbers have 2 adaptor plates. For a MC2100 &MC2150 motorcraft carbs there will be one. What is your timing set at? And have you checked your spark plugs? The gap?

I'm running the stock Carter Carb, and I haven't checked the gaps on my sparkplugs, I will do that tomorrow or tuesday. My timing is at 8 BTDC like said for the nutter.

That gap is for the stock set up. Not team rush mod (juice box) or hei conversion.

No weber, It's all the stock parts pretty much, what directions was it for the carb? I just remember the wiring, then plugging the distributor vac line to do timing.
