From: "olendorf" Maybe something inside the electric pump is defective. You can remove the electric pump entirely just for the test runs and see if that is causing the flow restriction. -------- Scott Olendorf Original Firestar, Rotax 447, Powerfin prop Schenectady, NY http://sites.google.com/site/kolbfirestar/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=443131#443131 ________________________________ Message 2 _____________________________________ Time: 07:20:37 AM PST US From: "Kirk Smith" Subject: Re: Kolb-List: Re: 503 DCDI cutting out. I think the problem might be the pulse line. I used regular fuel tubing for the pulse line and I was reminded it needs to be a heavier tubing than fuel line. So maybe the pulse line is collapsing at high rpms? Anyway I ordered some pulse line. Will know in a few days.

From: "Kirkds" OK...I think I got it fixed. Found a video on Utube on cleaning the pump so I took the old pump apart and cleaned it up . Then I took the replacement pump off and put the old one back on. Tied the plane to the tractor and fired it up. Ran it up to 5200rpms for 3 minutes back down and back up a few times. Ran perfectly on the impulse pump. I'll take her up this evening for a flight check but it looks like it's fixed. Thanks to everyone for the help. -------- Kirk Smith Columbiaville, MI Firestar II Read this topic online here: http://forums.matronics.com/viewtopic.php?p=443142#443142 ________________________________ Message 5 _____________________________________ Time: 06:29:51 PM PST US From: "John Hauck" Subject: RE: Kolb-List: 503 DCDI cutting out.
