'35 Accelerator rod/Oil Scoop Interference

[flathead34]

I have an interference between the oil breather scoop and the accelerator rod from the carburator on our '35. When I accelerate the rod pushes up the scoop. Has anyone encountered this before and if so how did you correct it? Thanks, Mike

I have the same issue. Form what I have learned it is NOT the accelerator linkage on the firewall. I believe I have seen some of the fuel pump adapters with a slightly longer upper steel tube. Many of the air scoops do not have the center tube spot welded to the outer scoop and since the scoop can fit low on the tube, this could be an issue. Beside the tube does not seem to fit securely in the adapter and may be fitting too low. I have not worked this all out yet and would appreciate how others view this problem.

34,
I wondered about that then I happened across a fuel pump stand that
placed the duck bill about 1/2" higher. It however is the '35 up style with the
2 protruding ridges on the aluminum neck. It would get the duck bill out of the way
but would not be correct.
It will be on my table at Gettysburg in 2 1/2 weeks.

Thanks Guys: I really want to keep the '35 fuel pump stand and not use the higher stand. The only solution I can think of is to file a groove in the bottom of the duck bill scoop for the rod to ride in so it does not raise the duck bill when I accelerate. Any other thoughts? Mike

Mike,
What I did on my '35 was put a discrete bend in the rod at just at
the right place. The bend leveled the rod where it passed beneath the duck bill
and from that point the rod inclined up to the carb.
I examined the higher stand I previously mentioned and it has 48
part number on it.

Charlie, I know the fuel pump stand with the 48 part number and I have one, but I am not sure it is right or a later replacemment for a '35. I like your idea of bending the rod. Thanks, Mike

How about placing a cork washer about 1/4" thick around the scoop neck that fits into the fuel pump adapter. This will jack the scoop up an additional 1/4", preventing it from going all the way into the fuel pump adapter. If that's not enough add a second washer.

Mike,
I think the f/p stand in your photo is the most correct one.....possibly
the f/p stands I have with the raised BANDS and 48 prefix are late production or
service parts.

Charlie, We bent the rod from the carb to accelerator linkage as you suggested and that solved the problem. Went back to our old pictures we took at Ford meets and found some from an orginal '35 Fordor and it had the rod bent. I posted that picture too. Thanks again, Mike

I was just getting ready to post that the accelerator rod on my '35 is bent to clear the bottom of the scoop as well, then I noticed you posted a picture of my cars engine. I am not sure if that rod was bent like that when this car left the factory, or if someone did this (possibly me) to make it clear.

Mike-

This is a very common problem especially if you have a vacuum plate(s) under the carburetor for a heater or overdrive. I think Ford also recognized this when it came out with the round cap sometime in late '37. A check of the "green bible" (pg 286), lists the round cap as the correct replacement cap for '35-'48." The duck bill cap is not even listed.

I have seen attempts of bending the accelerator rod to gain clearance under the original duck bill cap but when this is done it often pulls the carburetor throttle arm off of its' rest. This often results in the adding of a coil spring to pull the throttle arm backwards to create a resting position.

Adding a cork gasket under the cap might work but it also might hinder the bayonet locking of the cap. Still others simply rotate the cap slightly counter-clockwise to gain clearance.

I just went and checked my 35 scoop and it clears just under the scoop! I run the round one and keep the scoop for show only jm2cw. kerk

I would get rid of the scoop, it lets dirt into the engine one of Fords better ideas!

My '35 coupe that has sat since the 60's, has the rod bent.

I got rid of that dirt scoop! it will let dirt into your crankcase. the fan will blow it in. I have the breather that JM 35 sedan posted!
