ETW1 Carb. Adjustment

[Tinwoodsman]

I am rebuilding my ETW1 carb and need to replace the low speed needle valve. Can someone tell me a good starting adjustment for this needle upon reassembly?

 

[Bill W]

If by chance your referring to the idle adjustment screw in the base of the carb, Carter recommends 1/2-1 1/2 turns out

 

[Tinwoodsman]

That's the one, thanks. The Carter supplement to the TM did not give the adjustment information.

I will tag on another question someone may be able to answer. On my ETW1, the fuel intake needle in made up of 3 pieces. The needle (which is hollow), a spring and a small plunger shaft which rests against the float tab. The rebuild kit I purchased has a one piece needle. Will either one work?

 

[Bill W]

Yes ( but would have to use a different float level adjustment if you go and use the old 3 piece )
If you have the solid steel tipped needle throw it out and buy the one piece viton tipped needle kit from NAPA, the part# for the kit that will fit the ETW1 is 2-3516 http://www.napaonline.com/Catalog/Result.aspx?Ntt=23516&Ntk=Keyword&Nty=1&Dn=0&D=23516&Dk=1&Dp=3&N=0

Thanks Bill. Do you use the whole kit or just the needle? Does it come with instructions adjustment of the float level with this setup?

 

[Bill W]

If your rebuild kit came with the one piece needle than the float adjustment specs for the napa needle will be the same as the rebuild kit needle. You can use both the needle and seat or just the needle, if I remember correctly ( 14yrs ago ) I used both. The viton tipped needle worked so nice on my carb that I went and bought another just in case napa discontinued them ( Still have it!! )

Could somesone send me the TM # or post it .... or a link to where it lives?
That blasted thing is driving us nuts!

It is a supplement to TM 9-1826A. Chapters 12 and 13. 12 is the carb and 13 is the governor. I got mine from Midwest Military.

Finished the ETW1 rebuild today. Got the new kit from Vintage Power Wagons and it had everything I needed. Photos attached.

Can anyone tell me what the proper float level would be for the two different needle types?

Thanks

I would make sure that it is NO lower than 5/64" below the top edge when the needle closes. This is a good baseline starting point.

I just went through this sort of thing on my WC-63's carb. I found that I had to also replace the valve seat/inlet fitting in order for the new rubber tipped needle valve to work right. The needle would not seal completely until I did this, and the float level was so far off I couldn't adjust it. I have no idea what the original seat/inlet fitting was, or if it was original or correct etc. It was just clear that they had to go together as a set, and so I just went with what worked using the new parts.

i would use the old needle make sure its clean,and reinstall it,the aftermarket kits a re junk, they dont hold to specs.
