<html><body>I dont think its the wrench, as both fit. It is more about the type of fiber washer and the proper placement of it. If you "wiggle" the fitting as you insert it by hand it will help to not strip out the casting (which is the scrafical item). If it does not start in smoothly, STOP and redo it again by hand. Carb bodies are expensive. Yes, WD-40 or even a bit of red grease will help the mating of the two threaded parts. "Genuine" SU parts are the best to use if you can find them.

Sure, but 13/16" fits well.<br><br><br><div class="moz-cite-prefix">On 3/13/2023 9:37 AM, <a class="moz-txt-link-abbreviated">rct2bnc@aol.com</a> wrote:<br></div>

<div>I think that SU fittings are Whitworth size wrench sizes...not
13/16". And you can strip out the threads in the cast fuel bowl
lids.</div>
