My friend Andrews truck has been in Canada for a year... Its been in my garage since last fall....
The truck ran for a 1/4 mile and quit last spring He flushed gas tank, and replaced cap and rotor and wires. Rebuilt the Carter YF and replaced intake and exhaust gaskets..
IT WILL NOT RUN Its got fuel pressure from pump If you spray it with brake clean it will run for seconds
Andrew says get a new carb!!
Bright me reads about a W1 Carter I buy a re-built W1 from E-bay beautiful carb!!
duh doesn't fit stupid me wrong bolt battern YF is 2 15/16 W1 is different
I cleaned the tag on the door and confirmed its a 1949 3100
I checked engine and theres no serial on engine shaved off the block is 3835692 so its had a engine change to 50-52 235
so does anyone have a running YF carb 2100S ?? I checked with Bills Truck Shop and he won't ship carbs
Thanks I will we rebuilt it and had it apart several times if not its going into a shed Andrew has no patience for gasser he a real diesel guy he bought the 49 on a whim
An empty windex bottle with the pump sprayer works good.
The W-1 carb is correct for the 49, maybe the intake and carb was changed?
As fastax posted the needle could be stuck in.
bring the carb to me, i could very easily fix it, i think i may even have a rebuild kit for it. if the engine runs on a combustible sprayed into the engine you know it will run.
From the original description of the problem I would think its rust or dirt stuck in the low speed circuit. no you cant buy a new one and the only other replacement would be a rochester b that puke gas that will be a mixture of used clapped out parts. The yf is the best single barrel carb you can put on a 235 . easier just to find out what the problem is because there could be more problems with a replacement.
Problem with this one you will run out of steam at the top end with out going back and changing a bunch of stuff. These along with the rochester b were built for dozens of different cars they look the same on the outside but that's where similarities end. remans are usually a rag tag mixture of whatever parts they have because they rebuild them in batch lots. without taking it back apart and checking you could have anything in there . Rebuild kits can be as big of a gamble unless you get them from a specialty shop. To give you an idea here is a list of yf carb for chev I6
Here is a listing of the Carter type YF specifically produced for Chevrolet. Somewhere, I have a similar list for Stromberg.

This list taken directly from the Carter files. Note there are a few listed as "number assigned, no production". These were experimental carbs that were never produced. Unless I slipped up (certainly possible) this list is COMPLETE for the YF's for Chevrolet. There are many other YF's for other applications.
Jon.

well of course you do your homework and find a carb with similiar jetting and cfm rating. i wouldnt put a carb from a straight six on a big block, they may fit but wont work right. i also do some research and make sure the supplier knows what they are selling too. nothing worse then laying out hard earned cash only to get stuff that is no good or wont work.
It seems the carb, before and after re-build FLOODED the engine and fowled the plugs!! with gas hooked up it flooded....with no gas hooked up it would run on a shot of BC
Andrew and mechanic thing its a "Altitude" problem Truck lived its life on the "top of mountain" in Colorado...
I am proficient at removing and replacing... but I don't take carbs apart... I thought I was doing the easy thing, by buying, a rebuilt W1 for 200 bucks
We live 60 miles north of London close to Bayfield

Was the carb rebuilt? or did it just get a kit in it..big difference..doesit have a brass float or a cellulous one..have you actually had the carb on it or seen what is does.. have you tried to run it with the top off the carb to watch and see what may be happening with float, needle and seat, pump well??? they are about as simple a carb as you can get..It should be easy but I have said that before and then had to marry her, never trust a girl with peanut butter legs..... is your shop heated?? I hate the cold..and like I said before I have seen easy and sometimes it's easier said ...I am not to far away and could maybe find a time to come by ..where sactly is you....I am just off 23 by the cemetery north of Kirkton...on line 10 like to keep my eye on the cemetery make sure they keep the lawn cut, flowers watered and side walks clear in winter in case I get company I hate being alone all winter down there.. You couls also try to check out the stove bolt forum to see if anybody there has an sea-foam fix or a silver bullet..

The mechanic installed a "kit" I have not had it running, or looked "in" it
If I took it apart it would never go together again I have the patience of a 2 year old I'd thrown it in the garbage.... Yes I would
I would ship it somewhere, if someone would re-build it and receive large sums of money via Pay Pal or E transfer
The carb is off and sitting really no rush I can pull tne truck out and push in if I get a day that looks like spring (make that summer)
Carl..If for some reason you are in my area passing through you could drop that carb with me to take a look at if your not in a must have to-day thing..I am doing some renos in the house right now but if you can leave it with me and if you have the old kit left that he used I would like that with it I will take it apart and see if I can figure out whats going on....Chuk
