Looking to replace my vaporizer with a Holley NH carb & intake on my 26 Fordor.
Hey Dan, there are lots of stock intakes available on eBay - you can get one that is cleaned up and painted and ready to go for around $30 just search "Ford Model T Intake". Then, I'd get with Russ Potter on getting a freshly rebuilt NH. I'm not sure what Russ charges, but I'd imagine it's in the neighborhood of $115 or so? Might be more, might be less.
Dan you will also need to either make your own linkage or poke a hole in between #2 & #3 jugs (something I didn't want to do) this is a link to my solution there are others I'm sure http://www.mtfca.com/discus/messages/411944/452682.html?1402924346
G.R.- He may not need to "poke a hole" on a 26. The early 26 engines with vaporizers still used blocks with a hole between the cylinders making the change over very easy.
Mike did they have one piece valve covers or the 2 piece? if he has the one piece he may still need to drill that and that concerned me more than the hole in the cast web between 2&3 I'm not that familiar with anything other than a 27 because that is what I own.
I have an early 27 and the block has the hole in it.
One piece valve covers came out in 1921, they had a hole in the valve cover for the throttle rod to pass through. The 1927 valve cover with no hole was only used for a short time. Every 1926 engine block I have ever worked on had the hole for the throttle. Ford still used the NH carburetor in 1926 so they would still have a hole in the block for the throttle rod to pass through. They changed the choke design on the carburetors in late 1925 incorporating the "one knob" design to control needle adjustment and choke with the same knob.
Thanks Mike Looks like Dan gets to do it the easy way!
Question - how is the throttle linkage hooked up for a vaporizer? I see where G.R. has a little throttle arm but much higher up on the throttle lever than usual. Is the throttle arm in the right place for an NH on a stock vaporizer set up? (just wondering, never seen a vaporizer set up in person)
There is a hole between 3 & 4. My linkage to the vaporizer over top of the motor. How do I find Russ Potter?
Don't pay to much for the intake. I've got them laying all over for free!
He doesn't have a website that I can find but his phone is (217) 759-7592.
Here's your linkage:
Seth, the vaporizer linkage is attached almost at the top of the throttle control rod. When I looked at my throttle control rod there is a hole about midway down so I suppose you could remove the cotter pin and move the lever down the throttle control rod without much difficulty but vaporizer throttle went over the top of the motor instead of through it.
Ok, that's what I was wondering G.R., if the correct hole was drilled down there. If not, someone would need to measure so he'd know where to put the throttle arm.
The small throttle arm on the control rod used for the vaporizer is a different length than the one used w/an NH.
IIRC the vaporizer arm is longer than the one for the NH. I may have this backwards. The difference in length is about 3/8".
Forgot to mention: I wouldn't drill a hole in the valve cover side plate for the throttle linkage. There should be lots available w/the hole in them.
I've seen the beautiful work Russ does on carburetors, and that makes him the go-to guy for a rebuilt NH. But if you want to take the time to rebuild a $10 swap meet NH yourself just for fun, get the MTFCA book and have at it. I'd go to Russ or Stan for something exotic, but the NH is common as dirt and about as simple as anything can be. Just about any part you'll need is easy to get.
I have another arm down lower on the throttle rod. there is a hole thru the block and valve cover. I have a intake spoken for from Colorado. I just need to check on a carb from Ross.
Thanks everyone for your input and thoughts. That vaporizer is getting harder and harder to keep running smooth.
Thanks Again Dan
Dan I may be interested in that vaporizer when you are ready to dispose of it.
Dan, There were slight differences between the different castings of iron intake manifolds. The best flowing, but the hardest it find, were the first ones made after Ford switched from aluminum to iron as they used basically the same mold. A bench flow test revealed that there are differences even between later manifolds. Some people do not like the aluminum high volume intake, because it flows too well, I don't know why a gasket or a restrictor plate wouldn't slow the air speed down. As for carburetor, if I were making the change you are doing, I'd go for the best performing carburetor I could get and that would be a straight through Holley NH or a Simmons or Western Auto Wizard look alike (assuming you don't want to use an aftermarket carb like a Stromberg).
Also going to need a standard exhaust manifold.
Your right Erich, I do need one. Don't know what I was thinking.
Mike my early 22 has 2 piece valve covers
Dan, sent you a P.M.
Finally rounded up everything to switch over. I didn't think a T could run so sweet. Ran so nice, all the grandkids had to have a ride. Even drove it Sat. to the car show. Lot of lookers.
