carb rebuild kit

[jacksauto]

who has a good carb rebuild kit,i read blogs about some kits are better than others .some say use your old parts because the kit has substandard parts.i would like to get a kit I can trust will have everthing I need for a rebuild.any suggeastions would be appreciated.and how hard are they to rebuild.I have never done one before but a friend is going to help me, he has experience ....thanks jack

I worried about this as well. Purchased a re-build kit from Midwest Military. Took it to my local carb shop with a print of talking about these known issues, they reviewed it and studied the parts, said it was perfect no issues. So, from this we now know that MW sells carb kits which don't have the accelerator piston issue.

I believe that only certain newer manufacture kits have the wrong piston

Using any NOS repair kit for any component is not a smart move. I wouldn't offer them for sale, however some do and that is them for it I guess. You mentioned issues concerning the accelerator pump plunger. It has a leather boot, 50 year old leather is not a good idea, and it is certainly not compatible with today's gasoline. The metal parts in the kit may be ok, but I would even inspect them closely. Gaskets will not be good either. Any rebuild shop personnel that looks at that stuff and says it's good to go has a problem is all I know to say. They surely don't have their customers best interest at heart. There are folks out there who think any part with NOS on it has to be simply the greatest find since popcorn, the truth about that is they need to educate themselves. If said parts have rubber or leather components, fabric diaphragms, cork gaskets or seals, leather seals, it is crap in a box. Please bear in mind that it is of no concern to me how and what anyone spends $$ on; I just hate reading post like this recommending that people spend $$ on junk; I'm only sharing what I know is valid knowledge.

Tom Howell at Snake River 4x4 offers the best CURRENT production carb repair kits that I have found. We have built many ETW1 carbs using the ALFA Carter kits from Tom, never an issue. I certainly can't say that about the old NOS kit parts.

U are correct .It makes sense that NOS parts are not a good idea with todays fuels ,my truck ran fine when I got it going ,and after a new tank of fresh fuel it doesn't run at all.i talked to someone at VPW and learned about some additives to add to the fuel to help prevent the problem .one was seafoam and the other was marvel mystery oil...thanks for your input ,its fun to learn......... jack

I suppose it's hard for you to obtain non-ethanol fuel as it is difficult in most areas now. We are fortunate to have 1 station in town that does offer traditional gasoline due to the high marine usage on Lake Tillery. The additives actually have little effect on ethanol blended gas. Sta-Bil claims to have one formulated for ethanol fuels, but it's too new to tell if it offers any more protection than the others. Ethanol blended gas is a killer in small engines, outboards, and any older fuel systems, it separates rather quickly in storage and once that gets going, it makes a terrible mess in fuel lines, tanks, carbs, on valves, and everywhere else. The only way to keep this from happening is simple, don't let it sit in your tank more than a week or two. If your truck is not to be driven for a while, the smarter thing to do is run it dry and drain the tank. Run traditional gas if you can get it, even that should be treated and it isn't wise to let that sit for extended periods either, although it won't cause issues as quickly as ethanol blends.

For the record, I am not selling NOS kits. My kits are current production, made within the last year. They are compliant with today's fuel types.

Thanks for relaying this news John. I knew something sounded wrong with that picture.

Hi Guys,

Sorry for coming to this party late........but what's the issue with the accelerator piston in some rebuild kits? Is it the wrong part, or not included? Do you know which kits are bad and should be avoided?

thanks,
bob

I'm late for the party on that question too. We are very picky about parts we install in any component, so I have not had the issue of incorrect pistons as we have not changed suppliers or rebuild kit brands in many years.

From what I have read through Google, some of the leather cups are too big or two stiff and the springs are either to strong or two weak. I personally, made sure the bore on my carb was clean and free from build up and the pistol was polished to remove any corrosion. My kit was a new one as well. Once I made sure things were as they should be, the carb acts like it was supposed to. Your mileage may vary.

I guess I was wrong! Anyhow, the kit I bought from you worked great!
I forgot that accidentally saying "NOS" anywhere on this forum created such an uproar.

This is the question which I was attempting to address. It was my understanding that the kits which are incorrect are square top carb kits, but I may be wrong, clearly.

Yes it is fairly common knowledge about the spring issues in the Square top carbs, however those apply to civilian Power Wagons only. M37 trucks did not have the square top carbs.

Creating an uproar about NOS is not the issue; it is just straight up honest fact that much NOS stuff is no longer good because of age, many items do have a shelf life that is long gone, and many current production parts are simply better these days because of much improved technology in sealing etc. Keep in mind I'm not speaking of Chinese junk, you have to buy high quality current production components to take advantage of the better technology that is available today. A good example is oil seals. In some cases you can buy the best quality current seal for less money than some vendors ask for NOS seals that aren't worth the brown waxed paper they are sealed in. I recall advertised ultimate leak stopper kits for NP200 t/cases some years back. When you got it, the kit had NOS seals in it. They should have been called ultimate leak starter kits instead. Because all the parts were NOS, they sold like hotcakes. We resealed a number of cases shortly after the ultimate leak stopper kits were installed, owners said they leaked worse than ever after they installed the ultimate kits. My Dad always told me, son you have to pay for your education, ultimate leak stopper kits was a tough pill, yet a good educational tool for those not yet educated concerning NOS.
