[NSRCA-discussion] YS Problem

[Atwood, Mark]

Unfortunately today was my last day to fly prior to Muncie  (GO D4!!!!!!)

I’ll have to wait and try it there…  And bring a spare motor in case it doesn’t run.

I actually have a spare head that I will put back on (the non CDI head).  So that SHOULD work just fine.

Mark,
I have the El Nino and all the associated equipment (starter, battery, fuel, fuel pump, etc) loaded up and will be headed to the field from work tomorrow.

If you can get ahold of some JB Weld I will see you there.

Speaking of YS and fun, I am pulling a half the niter converting my Black Magic to electric... Hmmmmmm Let me tell you, it was NOT fun trying to get the nose ring out, damn that thing was in there good. Other than that it is going fairly well actually almost done staring at it.

In a word…  Crap!

Anyone else??  I’d like a second opinion!!!! (nothing personal Anthony but your opinion ..well…sucks. lol)   I have a feeling you’re correct though, much to my chagrin.  Not having a good YS moment.

Mark,
Bad news, you can not put that back in so it does not pup out again. From what I have read, that problem isn't really user serviceable. I have read posts of guys pressing them back in and even some guys using JB Weld to keep them in. Usually that is a problem that requires the engine to go back to YS.

Sorry to hear that!

Anthony

The short version…    YS1.70DZ – the brass fitting on the TOP of the head (towards the back) that has the black check valve pressed onto it blew out of the engine in flight!!  Needless to say the motor quit.

It appears to be a pressure fit.    I pressed it back in (I knew this wouldn’t work, but what the heck), started the engine.  It idled great, ran up great, took off, and as soon as the motor warmed up (about two passes, pulled vertical and POP…dead as a rock.  Landed… and the fitting had popped out again.

So I have a few questions…

What caused this to pop out in the first place??
What do I do to put it back in SECURELY

HELP!!!!

-Mark
