What would cause loss of all power [electrical]

Re: What would cause loss of all power [electrical

Yes, I have been doing some of that tightening stuff over the past few days.

Here's one picture of part of the manifold:
You can see more at:

(sorry - that pic was huge!)
 
Re: What would cause loss of all power [electrical

Hey.....any pics of the manifold for the twin SU's? That's what I was looking for.....I think the manifold on my A15 is home made, just trying to find out what the factory one looks like (haven't been able to find one on the net anywhere).
 
Re: What would cause loss of all power [electrical

Yes, I'll get that (somebody has one on the datsun1200 forum).
 
Re: What would cause loss of all power [electrical

Here it is with a pair of Hitachi SU's on it:

Re: What would cause loss of all power [electrical

Well OK then......I think I do have one! Let me examine it closer (and compare to your pic) before we get too excited.

BTW......I also belong to the Datsun 1200 forum. I registered a while back and lurk every now & then, but have never posted anything. I tried finding a pic of the manifold, but came up empty (must not have tried hard enough!). /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
 
Re: What would cause loss of all power [electrical

Take a look......it sure looks like the same manifold!

I am confused as to why the PO of my Bugeye would not use this manifold and instead fabricate his own.....who knows?

The question now is, should I keep it and use it on my car or should I sell it to you?? /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

Make me an offer I can't refuse!
 
Re: What would cause loss of all power [electrical

Maybe an issue with hood clearance.

Yeah....you're probably right. I was sort of thinking the same thing after I wrote it.
 
Re: What would cause loss of all power [electrical

But... it may be possible to have it milled down to change the angle (both on the head side and carb side). And... you may be able to shorten the top of the dashpots.
 
Re: What would cause loss of all power [electrical

That looks really good to me, add in a set of HS4's with linkage and I think I'd be good to go.

I already have a small hole in my hood, wth not just cut a bigger one if need be.

I found out just now that there's a screw on the front of the Hitachi I have here that you can only get to by removing the carb from the manifold.

Anyway - MrSprite, lets go to PM's or email and see what kind of a deal we can make shall we? I'm at:

Re: What would cause loss of all power [electrical

mrsprite,

looking at your picture I don't see any bolt holes at the bottom... What holds it on? Please don't tell me the exhaust manifold somehow has to be removed to get the intake off.
 
Re: What would cause loss of all power [electrical

Nope.....no lower bolt holes. I have a stock A15 intake with a 32/36 Weber also that has no lower bolt holes. I have never had things apart, but it appears that the exhaust manifold does in fact bolt on after the intake and holds the lower part in place. There are grooves on the lower lip of the manifold that would suggest this. It looks like the exhaust has to either come off or at the very least, be loosened before the intake manifold can be removed. Crazy.
 
Re: What would cause loss of all power [electrical

To my knowledge the exhaust and the intake are held on with the same nuts. Brass ones with a large washer. All the 948 thru 1275 have that arrangement. Not a big deal at all.

Aaah....but we both have Datsun A15 engines in our Spridgets! /bcforum/images/%%GRAEMLIN_URL%%/smile.gif It has a screwy pressure fit thing with the exhaust manifold clamping the lower half of the intake manifold to the head! There are only two bolt holes on each side....both are on top of the port.

Here's a pic: (the slot on the bottom is a water jacket)

Re: What would cause loss of all power [electrical

Hehe, well looks like it is nothing more than a modification of the A 40 design.

Leave it to the engineers to come up with strange arangements.

I'll bet that manifold could be made up from an original A15 downdraft manifold and a Sprite/MGB manifold, cut and welded together.

heheh... That would suit the FrankenMidget well.

I'd rather find the nice dual SU manifold I know was made for this head. Unfortunately it looks like I have to pull mine loose from the car before I can find out what I've got / what I need to get.
 
Re: What would cause loss of all power [electrical

I drove around for a couple years with a 66 Mini, 40DCOE Weber and a manifold that I welded up from metal plate and exhaust pipe. It really did work well, though I'd bet the flow was a little reduced from a MiniMania unit.
Here's one for sale right now.
 
Re: What would cause loss of all power [electrical

Buy in now price is certinaly right.
 
Re: What would cause loss of all power [electrical

Not really an option as I would have to take the car off the road while the work was being done.

This is my daily commute car, so whatever is done has to happen over the space of a weekend. Knowing myself I am sure I wouldn't get the old one off, cut both of them up and get them welded together and install new carbs and get them all hooked up and tuned over a weekend.

Just taking off what's there & bolting on a new one with SU's already connected would be possible. If I installed the carbs on the manifold and got the linkage all working right beforehand. Then just remove & replace and connect up a couple cables, vacuum lines and fuel. That could work.
