The Stovebolt Site Forums The Shop Area Engine Shop I.H. carb on a 1949 235

I just tried a carter w-2 carb on my 235 1949 and it leaks bad out the shaft area.
so for the heck of it i put one off a I.H. bd220
i have.bolt pattern matched. it seems to run with it on the stand.havent tried in truck yet.
anyone used one of these holleys off a I.H.is it ok
to use. thanks

You may want to look at the linkage connections and also check into the metering rod sizes to see if they are close to the original carb for your truck. I think you mean a "W-1".

A carburetor is simply a chunk of metal with a hole in
the middle for air to pass thru with another hole
plumbed into the side from a source for fuel. If you
can get it to fit and get it hooked up to the controls,
fuel and vacuum lines then sure it will probably run.
How well it will run is another matter and if the
throttle shaft is badly worn it will still run the
engine but not very smoothly. Is it ok to use? All
depends on what you're expectations are.

Denny, That's the BEST description of "applied carburetor science" I have ever seen in print! My hat is off to you!

Don't forget, I've got one of each bolt pattern carb you can try on your engine if you like. Dave

Two stovebolters in a community 5003 people? Are there a lot of old vehicles up in Homer?

Not a great amount of old vehicles, I know of several. There is at least one more bolter that I'm friends with, Homeradam. Now that I think of it I know of at least 2 early 40's IH pickups and another 46 chevy pickup, my neighbor has a FULLY restored AD that is beautiful. I know of another AD that was done by patricks.

Went to the street view on Google maps and din't see any of your
vehicles out in the yard, ya must live out of town Homer. Must
be a lot of tourist traffic up there with all the museums I saw.

RW, I'd look up the other guys and see If I couldn't find a carb
designed to fit your truck.

Being a bit of a carter guy I'll pass on that the carters were very, very specific about the carburetors they made for your engine. Try to find an original designed for that engine and then rebuild it - get the carter spec sheet and follow it.
I had no idea carter was so precise until I started to buy up old inventories - they were manic about them.
What IH carb, a tillotson or zenith? is that what they used? I've always had deep respect for the IH carbs but never did one from late 40's

As long as the throttle arm has the correct orientation to work with the throttle linkage, and the carb isn't worn out, shouldn't be an issue. Rebuild kits, other than floats, are easy to find, and they take the same jets as the 2 and 4 barrel modern Holley carbs. I'm running a pair of them on mine, sourced them from a later 240 Black Diamond. I did have to modify the linkage to make them work, as the IH intakes are on the opposite side of the engine from Chevrolet.

that google earth map if its witin about 2 1/2 years
should show my truck as it hasnt moved in that time!!!
wife giving me a little more time before she plants
trees/shrubbs around it.
the prob I was having was finding a carb that had
the tag on it. dave is offering to let me try a couple
he has. got a newer 59 engine see how the new ring job goes.

Yep, that's what'ca need rw, a buddy close by who you can swap
ideas with. Sounds like there are a few of you right there in
Homer.
When you're working with parts that are more than half a century
old such as a carburetor, you can bet the farm that it's been
rebuilt at least once probably several times. A lot of guys
neglect to put the tags back on, I suppose the train of thought
is that once they rebuild it, there won't be need to do it again.

I'm pretty sure Google earth is up dated more often then that so
you probably are on stage. Of course, I didn't have a chance to
canvas the whole town. I was thinking McCabe and Mrs. Miller,
instead you guys got a sprawling metropolis up there.
