2.5 T-Maxx HSN vibrates out of adjustment

[SWMichgander]

Hey Folks, The High Speed Needle adjustment works it way out of adjustment as I run my T-Maxx. Is there a way of tightening the HSN so it doesn't want to back out of adjustment, which makes the fuel mix way too rich. Thanks for your comments.

Wrap a zip tie around the needle, making sure to catch some of the housing as well. Works like a charm but is quite ugly. Replace the o-ring for a permanent fix.

I'll give the tywrap a try first. Thax Matt.

I had a 2.5r that did what you're experiencing. Funny thing was, it didn't leak at all. So I really can't say for sure if a new seal would fix it properly or not. Either way, it's a helluva lot more fun when your engine doesn't tune itself. Watch the lsn as well. A little blue locktite on the lsn threads fixed mine right up.

Thanks for the advise on the LSN as well.
