I just installed mine this afternoon. It is a quality product. The components are well worth the cost. Easy to install. I haven't had much chance to test it out yet. Starting is improved, though wasn't a problem. Greatly improved idle, particularly when cold. I don't notice a difference in power or acceleration, though that may come with a little more spark advance. Overall it appears to be worth every penny. A stronger spark will ignite a lees perfect mixture. A less than perfect mixture is the nemesis of BBD carbed Wranglers.

I'll let you know more after the weekend when I have a chance to drive it more. I think you can't go wrong with this product.

you're taking up too much space.

yes I too have also done this and it starts easier and runs better but my nutter bypass top it off a long with the weber.So if you try these mods it maybe the only ones you will have to do.The TFI that www.driveajeep.com offers is probaly the best way to go because some of these parts are hard to find.Plus the coil comes with its on mounting bracket and can be bolted right on the passanger side finder.So no worring about making a setup for it. plus it comes with all the wires and stuff you need.Put it on set the timming and go! thats it!Later

go to www.Jeepz.com they have a carter BBD carb fix that would fix your cold idle and starting. The problem on the Carters is the Venturi clogs, which gives you a rich mixture, ther is a write up there, there is also another write up on a TFI upgrade with parts from a Ford 300CID I6. It has all the parts numbers you would need, so you could go get them at the local parts store. Good luck

Found a 85 CJ7 tub in good shape with
minimal rust. The resto continues....
