Hand Throttles
What all is involved in the mechanisms that operate the hand throttle on a 226 6 cylinder flathead with single barrel carb? I have the ****,cable and pivot piece on intake manifold. Was there a cable catch piece or a point else where that holds the cable housing so throttle could be operated by hand easily? Also why do some trucks have the hand throttle and others not and what was the reason that Ford offered a hand throttle other than may warm the engine up? I've heard farmers liked this for plow work.

Is this a combination throttle and choke? I had one like that on my '55 with a 239 V8 and single barrel carb. It worked well to start when the engine was cold. The **** was labeled choke but it advanced the throttle also.

The throttle was available standard on the bigger trucks at least F-350 and up maybe F-250, and as an option on the F-100's. Roger, this was separate from the choke. If the truck did not come with this option the dash had a dash plug filling the hole as my F-100 does. The bigger trucks needed it to operate the PTO or hoist or dump and other equipment without the driver having his foot on the accelerator.
On the farm as a kid my Dad's 3/4 ton '48 Chevy pickup had the throttle ****. I remember I would steer the truck in the field, my Dad would set the throttle and my Dad, Mom, brother and sister would walk along the truck and pick up stones, pick corn, etc. All I had to do was steer it straight and when we would come to the end of the row my Dad or brother would take over and I would slide over. When I got older I was out in the field working and the truck would steer it self in the rows or my little sister would steer it.

No, it is not a combination with the choke, but a separate piece. It is used to control the speed of the engine when the pto on the transmission is engaged, or when using a belt driven accessories such as a welder or AC generator. Generally there is some other linkage on the carburetor to allow normal operation without disturbing the throttle cable.
They do not work so well with loads that vary - but are common on trucks with hydraulic pumps, winches, and other such loads.

It sounds like Abe knows from first hand experience. The truck is a F-1 with a grill guard.......farming. Did they have some kind of cable catch or holder that gave stability and a "straight shot" to the carb. I say straight shot because that control cable comes from under the gauge area shoots through the firewall and takes turn across the top of the motor and over to the right hand side to link to carb. That's quite some turns to get free travel and smooth operation without binding. I can't see anything obvious in the 1949-51 Shop Manual for pictures.

I have used a hand throttle on a 5 ton line truck with a PTO winch. It was an old International we had in the Telephone shop while I was in the USCG. The throttle and winch controls were at the back end of the body. The throttle control was a **** you turned to speed up the engine. I did not know you would find one on a 1/2 ton pickup though.

I found a few illustrations in the 48-56 Ford Truck Catalog that show choke and throttle cables but they don't give detail of how they connect to the carb. The throttle cable is part number *1HC 9775-A. The * means the part number was superceded, catalog was printed in 1964. Under the description in the text catalog it says it is 47.00 inches long - cut from B9TF 9775-C for the 226 engine in a 51/52 model F1, F2, F3, F4, F5, F6. So B9TF 9775-C would be the replacement part. The B9TF 9775-C is 125.00 inches long.

I think what you are asking about is the bracket that attaches to the screws that hold the air horn to the float chamber section. The bracket for a choke-only carb had just one arm sticking up from the bracket, on the right side. The choke/throttle bracket had two arms; one on the right for choke, one on the left for throttle. They obviously hold the sheath, so the wire inside does not bind. They were generally found on the 8RT carbs.
