1978 Pickup, giving her some love...

This is the carb.

[Jims5543]

And thisbis the hose that broke. Seems to be rekated to the choke somehow.

[94touring]

Yep.  Head into the store and browse the carb rebuild parts and gaskets.   I'm too rusty to look at the pic of your carb and identify the model.

This is the correct carb rebuild kit

[Jims5543]

This is the same rebuild kit for the same price and it is sold by our host.

I went with this one.

[Mudhen]

They don't look the same to me...never seen one like the one here before.  It has a metal body and plastic emulsion tube???  Interesting...

(I've never seen one of these carbs in person, though, just the 1 1/4" 'ers whose jets look like the 7ent ones).

[94touring]

It's actually the same as this one they sell.

Although upon further investigation this metal style is for a later model, but this one is the earlier style.  Guess I can raise my price on the other one now, lol.

Here we go.....  Carb is pulled, valve cover is loose, pulling plugs and alternator tomorrow, throwing in new rockers and rebuilding Carb.

I have never rebuilt a carb before, any tips?  Is there a good DIY thread somewhere? You Tube Video?

I am also pressurizing the AC system and marking the condensor leak, gonna pull it and either solder it myself or have a radiator shop do it.

Hope to have the girl back on the road in a few weeks.

[94touring]

Nah just tear into it man 77.gif.   You'll need to torque the rockers to a specific setting though.  I had to take down my Haynes manual pdf files that had the torque settings,  but I bet you can Google it.

[Jims5543]

I have a couple of shop manuals, I was planning on looking that up.

Did a search on an HS4 rebuild and there are some MG rebuild Video's.... close enough.   ;D

I miss driving her and really want the AC working again.

[Jims5543]

Started putting in the new rockers this evening.




Then this happened.  Dan, you have the same rockers. I am not very confident in these anymore. As I was tightening the lock nut and holding the screw tight it came apart way too easy.



I scavenged a screw off the old rockers and hope I can use it. I will try this again over the weekend, the weather is better here, so the boat is back on the front burner.

[94touring]

Ironically I have done the same thing before, busted a bolt, and I was pissed the hell off.  They are easy to over torque I guess.  I had to order a new bolt, but I suppose you have some extras laying around? 

[Jims5543]

going to see if the bolt from the old rockers will fit in there.

I was so pissed off I just put away the tools and walked away.....

I will revisit this on Sunday.

[94touring]

Yeah happens.   Kind of funny I get to relive some of my past agonies through you lol.

[Jims5543]

BTW- Looking in the cylinders to get to TDC of each, I noticed #4 is really carboned up inside. I am sure it is a result of the rocker that was not functioning.

I was thinking I spraying it down inside with some sea foam and letting it soak while I work on the other stuff and see if it clears it out some.

Yes?  No?

Leave it alone and just wait for the inevitable engine rebuild?

[Jims5543]

This was me in the garage after the bolt broke....

[94touring]

Great pic ;D.  I've heard good things with sea foam.   The flur car apparently got a treatment before I bought it to clear a sticking valve.

[Jims5543]

Showed that pic of the snapped bolt to a good friend of mine that is a aircraft mechanic and he said even Ray Charles could tell that was a defective bolt and to be very weary of the rest of them.

[Jims5543]

2 questions...


1. When taking apart the carb I noticed the float is filled with fluid. Is this normal or is my float effed?


2. I have my carb rebuild kit, and my Jet Assembly is different that what I have on the car. I cannot get the linkage to hook up.

Red is the new one black is the old one. The new one is about 90° different where the linkage connects.

[94touring]

Hmmm ok let me post some pics and we'll look at the orientation 8.gif 

Ok this is a red hs4



Black HS6



And Black HS2 

[94touring]

Wait...this may explain it.

[Jims5543]

Looks like I need a 9142, I have a new 9141 and it does not fit.

I am this close to dropping $500 and just buying an entire new fucking carb. This car has been off the road for almost a month now and I am getting frustrated with the setbacks.


Anyone that says a rotary car is unreliable has not owned a Mini.  Next time I see someone post something online that says something along those lines, I am going to laugh at them.

[Jims5543]

Well, blessing in disguise, I was looking over the fuel lines in the engine bay, I am not happy with the routing, the current route takes if about an inch from the exhaust header which seems stupid to me and most likely a reason for hot start issues.

I am stopping off at the auto parts store tomorrow and buying soem hard and soft line to re-route it up an away from the exhaust.

I am also going to see about fabbing a heat shield to protect the bottom of the carb and deflect some of the radiating heat from it.

[Mudhen]

Sucks, I think most of us have been right there with you at some point, though.  It will get better!

(only kidding, it won't, but don't want you to defect so soon into your ownership  71.gif )

[Jims5543]

Gas line purchased hope to have some time tomorrow to start routing the new line in.



Question, I am having a hard time getting this evaporator repaired, the shop I went to which I was sure could do it cannot work on aluminum so I need to find a tig welder that is willing to work on a evaporator.

I would prefer to just buy another one, anyone have a clue where I could shop for one?

I can take a few pics of it if needed so we can identify if it is an Austin (BMC) part or aftermarket.


Option 3 is to grind it down some, clean it up real good and try to pug the hole with JB Weld and see if that holds. Hell, I had JB weld in the intake ports of my RX7 motor where we ported into the water jackets doing an insanely aggressive porting job.  It has been in there for years and lots of miles problem free. Decent pressure and lots of heat.
