Carb o rings

[upbasher1]

Have been looking forever and cant find them. I need a part number or some place to get the two o rings on the carburetor neck. I'm pretty sure they are for the most part the same size on a lot of big blocks, so they don't necessarily have to be hpi Thanks in advance

@upbasher1 The S-25 (4.1 V1) savage engine complete O ring kit is HPI 1450, They show the two carb O rings as 10 x 12 x 1.0 MM ( NOTE: DON'T BUY FROM ACTIVE POWERSPORTS !!)

The pic below is for the HPI 4.1 V2 engine and shows the two carb O rings as part # 1469 and the complete O ring kit has the same part # as the 4.1 V1 and the 4.6 V2 engine as 1450 .

Also if your O rings aren't damaged just put some O2 sensor safe high temp silicone on carb neck where O rings are & reinstall carb. just like you would if you were sealing your engine from brand new or after a tear down or rebuild.....

Thank you for that. Unfortunately you can no longer buy them anywhere. I did however find this:

Apparently they can withstand up to 400 fahrenheit, and are resistant to "aromatic" fuels. I'm not familiar with what "aromatic" means in terms of fuels, but they are only 6 bucks and you get 10 of them, so I'm going to get them and let one sit in some nitro for a few days and see if it ruins it. If not it may be a viable alternative to the discontinued ones will update

And I do always seal my engines also, I just like having good o rings in there that arent all tore up lol.
