That doesn't look good, how long has that carb been on there since he rebuild? I'm not really sure how to fit that, but I'm sure Jim C could help you. Hope for your sake that he is "The Man".
 
Could this be caused by having the fuel float level set incorrectly? The fuel level looks to be a little on the high side in the sight glass - more towards the top than the middle.

Is this normal? Is there and obvious fix?


Fuel level should not affect that.
It is almost normal..lots of carbs do that, but yours looks a little excessive.
Did The Man remove and replace those butterfly shafts?
That is a difficult task to do correctly, and I would trust that only to the carb gurus on 'Mud. I believe that the gurus here have the ability to re-bush (or something similar) those shafts.
 
Rereading my last post. . . I didn't mean to insinuate that I rec'd bad service from my carb rebuilder (not Jim C.). Just that I mentioned to him that it started weeping from the throttle shafts after reinstalling it. He can be really difficult to get a hold of. . . so during the reinstall and tuning I kinda gave up trying. He doesn't do public email, so it seems I just end up trading phone messages w/him - when his machine is on and/or not full! Now that the problem has evolved from just weeping to something more serious - gumming up the throttle shafts - I am trying to communicate w/him again for some assistance/guidance.

I don't have my receipts in front of me at the moment, but it's only been installed for a few months since the rebuild, and just used for around town miles. . . and not many at that.

I don't think the butterfly shafts were rebushed or replaced during the service. One of them was frozen and required some work to get it freed up. . . the carb was not in the greatest shape to begin with.

Mostly, I'm looking for some guidance as to whether this is normal or not (sounds like it's not) and if it's fixable or not (sounds like it is, by the right person).

Thanks for the help,

Tom
 
Or give Jim Chenoweth a call at (740) 862-2604, I'm sure he can get you pointed in the right direction.
 
Thanks for Jim C.'s info. I've been holding off contacting him while I do some additional troubleshooting and give the rebuilder a chance to return (from vacation maybe?) & turn on his answering machine again etc...

So this AM I pulled the carb off for a look-see and found quite a bit of varnish to say the least. The photos from inside the manifold & of the carb underside look wet, but are in fact dry to the touch & shiny. . . nasty stuff. I am now thinking this may be a bad/old fuel issue and not solely a leaky carb issue. The carb did weep from the throttle shafts from the get-go, but the varnish can't be helping.

A few pages back, I showed the nasty, gummy NAPA gold filter I swapped out after running the first tank of fuel through. I haven't replaced the stock one yet, but I bet it is just as nasty. I bet some (or a lot) of that nasty, gummy old gas made its way through and stuck butterfly's are the result. . . I bet some of the jets need some attention too. . . time to clean my newly rebuilt carb?

So would this happen with normal, healthy gas? Or is this an obvious by-product of old, bad gas?

Thanks,
Tom

Tom when I was struggling with a vacuum leak on my 40 I too noticed some weep at the carb base. I also noticed what I thought was oil on the bottom of the manifold.

When posting in Tech I learned that some weep is normal and that what I found in the intake was actually the heavier gas distillates that had not evaporated. But you can see the color of mine and it's much clearer and was like a light oil to the touch. I don't know what explains what you are experiencing. Best of luck.

I think you have two separate issues - the carb and what is going on in your manifold.

I would be less concerned with the varnish in the bottom of the manifold. If you have to pull the carb again to ship it off, you could pull the manifold as well and sent it in to the shop for a trip through the hot tank. Or you could just try the family dishwasher and see how angry your wife gets... :D

I personally would have replaced both filters before bolting on a freshly rebuilt carb, but that is just me.
 
You ALWAYS replace all your fuel filters when putting on a new or rebuilt carb. I think you may have a lot of gum/varnish stuff deposited in your old fuel filter, perhaps running fresh gas through it is dissolving some of that and allows it to flow up to the carb. That looks like a lot of filth for such a short period of running.
 
OK, so I don't sound like a complete idiot, let me be clear. . . .

Before I started the engine for the first time a few months ago I did this:

Sent the basket case carb out for a fresh rebuild
Pulled and rinsed the fuel tank (did NOT hot tank it)
Replaced ALL rubber fuel lines w/new
Flushed all metal fuel lines
Replaced OEM fuel filter w/new
Added an ADDITIONAL NAPA Gold fuel filter in-line before the OEM filter
Fresh fuel

So when I started the engine for the first time, with the fresh(er) carb., it not only had one new filter, but TWO.

I think my mistake was not having the fuel tank hot tanked. I'm sure the fresh fuel softened the varnish that I wasn't able to clean out myself. After running it for a bit, I noticed the NAPA gold filter was filled w/goo. Not dirt, but definitely old fuel/varnish/goo. I swapped it out for a clean one, but did not swap out the OEM filter at that time. The NAPA gold one that's now been in for a bit still looks OK, but I bet the OEM one isn't so good on the inside. . . .

My guess is that enough goo got through the 2 filters that it started to freeze up the carb. . . is that possible?

I spent today taking the carb apart and cleaning it - it was filthy on the inside and took a 3hr. soak in carb cleaner to free the butterflys. Kinda surprised how much grit was in the float bowl being so freshly rebuilt. none of the jets were clogged, but I sprayed out all the nooks and crannies anyway - a good deal more junk came out than I expected. I've never run w/out an air cleaner (which was also new a few miles ago).

Anyway, I should have it back together by tomorrow, but won't run it again until I swap in a new OEM fuel filter. . . . I'm hoping that'll take care of it for a while.

And so it goes. . .

That makes the most sense to me.
 
You don't look like an idiot, no worries.

Filters are cheap, if you suspect goo in the tank I'd buy a flat of those cheapie NAPA (3002 I believe?) clear, see-through ones and be a little OCD about changing 'em out!

Then DRIVE that Piggy and put a few tanks of fresh, $4/gal gas through the system!

You have made great strides with that Pig, endeavor to persevere!
 
Ok , the most overlooked part of a tune up is the PVC valve , we the crankcase not being properly vented the bypass oil will take the path of least resistance through the carb , check it out

It's been a while. . . But we've been doing some driving!

Picked up most of the 2F pieces and parts from the machine shop, but haven't been motivated to start cleaning and assembly. . . we've had a few peeks of summer so I don't feel like being trapped in a project at the moment and the original 1F is running well enough to get us around town at the moment so. . .

We took the pig for a good mud bath today:

So, how much did it take to get it back on the road?

Still thinking of selling it?





Hello -How much might I need to put into it to get it on the road? $2K, $3K, $5K? and would I likely be able to sell it for what I'd have into it a year or two from now?


Thanks so much for your input.

Tom

My initial cost was basically zero. . . (still need to pay my friend $250 + a drive!). So not counting the 2F, I am just about right at the top of the budget I set at the very beginning - around $3,800. A few big ticket items account for a large percentage of the total:

$450 = Carb rebuild (+Pertronix)
$800 = Seats recovered
$5-600? = Tires

The rest was just little stuff that added up. 100% of labor (me) was free.

I probably could've done it cheaper, but I replaced a bunch of little stuff that added up cost wise in the hopes for longer term reliability.

Haven't been thinking of selling it. . . I doubt I could get back what I put into it especially if I included the 2F. . . not that it's all about the money, but at this point it's probably cheaper if I hang onto it!

Hello -

After much debate, I've decided to try to sell our Pig. I just haven't fallen in love with it like I have with some of my other projects and having 4 vehicles is kind of silly for 2 drivers. . . I've been waffling back and forth for a few weeks, but here we are. . .

Here's a link to the ad. https://forum.ih8mud.com/fj55-classifieds-corner/605316-1972-fj55-sale.html

If you're interested, please feel free ask any questions etc....

Thanks,
Tom
 
Gosh when I get below 4 vehicles for our household I feel like my driveway is empty. I also have 4 motorcycles, down from 5 though... Good luck with your sale
