Why is my top speed 70 mph?

I mean no disrespect when I say following, so please don't take it as such. Now that I have said that, if you do take it that way, it's all on you.


First, from your original post and responses, it sounds like you have very limited knowledge of automobiles. That's cool. We all did at one point. That said, I highly recommend that you get a FACTORY Chrysler service manual for your car. We have them available somewhere on this site as a linked download for some models for free. If yours is not among them you can find one on Ebay. And I mean FACTORY CHRYSLER, not some Chiltons, Haynes or other craptastic garbage.

You said you did the test I outlined. I did not ask you if the carburetor was opening. We all already knew it had to be if the car was moving. I asked you to check to see if it was opening ALL THE WAY as far as it can. If you did not physically GRAB the carburetor linkage while someone had their foot to the floor on the gas pedal, you did not check it as outlined. Your answers there have been very vague and unclear at best. Much like a mud puddle.
