I've not seen any posts from you about trouble with your .46, since you were messing with the LS needle. What trouble are you having with it, it is a much more powerful engine than that LA. It would be worth your time to troubleshoot it, rather than junking it.

What's it doing (or not doing)? Maybe we can help! It's important when troubleshooting that one thing is tried at a time, so as to not create more troubles than you're fixing.
