I can identify with: "I'm gonna go out and fly this thing no matter how bad it sucks out there.....!" to check something out.. Nothing like a little addictive/compulsive behavior to get something done....:0)<BR>

<BR>> From: bob.lavey@cox.net<BR>> To: nsrca-discussion@lists.nsrca.org<BR>> Date: Mon, 1 Mar 2010 14:52:34 -0600<BR>> Subject: [NSRCA-discussion] Solved: YS 160 question<BR>> <BR>> It was the check valve, I'm nearly 100$ certain. I pulled all the fuel<BR>> lines from around the engine: case-to-pump, fuel dot-to-pump, pump-to-carb,<BR>> carb-to-injector. They all looked fine and passed the blow and suck test,<BR>> but I replaced them anyhow. I pulled the check valve and ran a new piece of<BR>> line from the carb to the injector. I also checked the plug while I was<BR>> under the hood, and it looked fine. So, since it's 45 degrees, overcast,<BR>> and there's a 12mph north wind, I went out to the field to see if it was<BR>> better. It was going to bug me until I could check it out :) I reset the<BR>> needle and regulator to their previous settings and gave it a go. It<BR>> started right up, idled fine, transitioned fine, ran good in the mid-range<BR>> and top end, and seemed to have more power. So it put it in the air. I<BR>> pulled into the square loop, and at 1/2-2/3 throttle it pulled up and up<BR>> like it always has. Yay!<BR>> <BR>> I found a post from Troy Newman on RCU saying you could run without the<BR>> check valve, or I'd have never tried that on my own. It's good to know, in<BR>> case this happens again and I don't have a spare handy.<BR>> <BR>> Thanks to everybody for their suggestions and assistance.<BR>> <BR>> Bob<BR>> <BR>> <BR>> > -----Original Message-----<BR>> > From: nsrca-discussion-bounces@lists.nsrca.org <BR>> > [mailto:nsrca-discussion-bounces@lists.nsrca.org] On Behalf <BR>> > Of Bob Lavey<BR>> > Sent: Monday, March 01, 2010 12:07 PM<BR>> > To: 'General pattern discussion'<BR>> > Subject: Re: [NSRCA-discussion] YS 160 question<BR>> > <BR>> > That’s a great idea, Glen.
