Saturday I traded my '31 flathead model a. I got this '41 willys pick-up. It was an old build that needs to be gone over. anyway my question is if it has a bad trans. modulator valve, of if its not connected will the car stumble and stall when put in gear?
cool truck. the willys panel is tits too couldn't be any vaguer? I have to say no, but it would make it not shift
I didn't get a chance to look at the truck yet, I do know when put in gear it stumbles and stalls out.
Could be as simple as a carb adjustment. Whats it got for a drivetrain? What carb? How about a LARGE engine picture?
heres the motor a 350 chevy with this unusual set-up. its two side draft mikunie carbs. this is the first I seen this . I want to keep it on, but I don't know to much about these carbs,niether did the previous owner he had 9lbs of fuel pressure, the idle set screw was all the way out, and the idle mixture screws were at 5 turns out. I need to find more about these carbs., don't want to go with a four barrel that everyone has.
Go with the 4 barrel; for now. Send those off to Jim Inglese in CT., he will make them run like a top. There is a science to setting those up, and he knows how they work better than anyone. I can tell you right off 9 psi. is way too much. Idle mixture settings sound way off too. Might need closer to 2.5-3 psi. for fuel.
That carb setup looks like a major headache. If it was a reliable, efficient setup they would be more commonly used.
Cool looking set up but looks like a head ache to toon !! I would swap out for a 4 barrel and go from there . At least you can hopefully fine your problem! Good luck
This truck was built by Rob Ida in the late 80's early 90's. If you don't know who he is google him or Ida automotive! Posted using the Full Custom H.A.M.B. App!
32 fenderless, I know Bob built it. he's one of the willys guro builders. I just need more info on the carbs.thanks for your response.
If your modulator valve is defective, in that diaphragm is broken, then you have a vacuum leak. When you put it in gear, rpm drop combined with the leak, could be causing it to stall.
so Algoma 56, a bad modulator valve WILL make the truck stumble and stall out when put in gear, is that what your saying, because that's what I thought it could be.
so today I changed the base gasket on the B&M blower thinking it was bad and loosing vacume. well it wasn't that, and I then went out and bought a edelbrock 1406 four barrel. tomarow i'll install it, hope that's the fix.
Ummm.....I don't see a blower....maybe I'm missing something.... Posted using the Full Custom H.A.M.B. App!
well the top part of the manifold where the carbs mount to. I was told by a guy that does weber set-ups that's what he called it.
Are the pipes black? Could rule of if its running rich or not. Does the dist. have vac. advance, its hard to tell in the pic. Check vac. source to it, if it does have one.
vac. ad. is hooked up. I got the carb the best I could took it out today, takes the throttle ok, but at stops it wants to stumble and stall
It sounds like a vacuum leak to me. Do you have a vacuum gage? It should be steady and read between 10 and 17 in.hg. at idle, depending on what cam is in it.
