You're 100% correct on that. If you know what you're doing, however, you can get a decent carb pretty damn close. They don't have to buck when they're cold.

I'm certainly not trying to be a prick but does a Howell cold-start any better than my video?

The same thing can be said about a leaf spring suspension. Does this mean we should all be running a 4-link?

Manual transmissions are also antiquated, so I guess that means we all have to switch to automatics.

Then there's that darn blocky body that's prone to rust.....

Believe it or not, some of us get along just fine in cold weather with a carb, and we don't have any of the drivability issues you've described.

think about how many 25+ year old carbd vehicles got along in Alaska this winter just fine? Now I would not want a soft top in -50 personally as I know how it is -10 with a soft top and the willys running that old YF got a long better in the bitter cold than me. -16 was the lowest recorded temp where i lived in PA. Im not knocking on either fuel system as they both deliver fuel to the pistons. I do however like the simplicity of my carbs and im not talking about the ones that are ate either.

That is not the case with FI and that is what I said earlier.

I can say that they they will defiantly run without having to feather the throttle and without any hesitation or bogging when everything is correct. They are old technology but vehicles ran fine on them for almost a hundred years in all kinds of weather.

Shawn, I don't have a Howell system, it's all GM with a modified Motorcraft distributor, big cap, GM coil and Bill Hamilton's tune, I *do* think your Jeep starts faster than mine.

Matt, 'Gypsy, I would love to see you guy's ditch the mixing box but I will bet you don't plan too.

I will still give you chit and you can do the same to me for making a simple Jeep more complicated.

But the question is not which is best. And I myself, do not see any great boost in reliability, performance or fuel economy with FI over a finely tune carbed engine! At 0* (-22* wind chill) a few mornings ago mine started right up and drove off with no problems what so ever! Ounce the OP gets the engine/carb dialed in it will run fine! This MAY mean more than just the carb, everything has to work together, until that happens, its a turd!

My dad (50+ years Master Mechanic) has always said to set your choke so even when closed it's not really all the way closed, it still has about 1/8th of an inch gap, which your choke pull off will then pull open a little further. If you have it closed tightly it may be closed too tight and even when fully warm your choke may not have the movement to open it fully and during warm up it could take longer than it needs to in order to open it. I have always used that setting on every carburetor vehicle I have ever had and as long as everything else works properly that works great. Always starts right off and warms up properly being able to drive them as soon as they start if needed.
What in the world are you inferring?

Grammys works just fine setting it the way the manual said to set it.

I was going to shoot a vid of it starting after sitting for 4 weeks then within 1 min back it put of the garage, put it in 4low lock the hubs and park it on the snow pile so I can work on my Saturn.

It was 17 outside.

I was scratching my head over that one too, 86.

My new procedure is to just tap the throttle enough to set the choke and turn over engine. It starts all by itself just before the oil pressure builds. No throttle pumping.

I find in normal weather one pump to set the choke and prime it works well. I find when it gets below freezing, more pumps to prime are required to get that fast start. Yesterday at -22C I used 3 pumps and it fired right up.

In 15 F weather here and sitting for weeks at a time I like to turn it over and get oil going before the start.

If I pump gas even once in this weather it lights off directly.
