Gradually they got worse at atomizing the fuel and I wasn't able to run as lean. Its easy enough to do that I'll probably do it at each annual. 1 hr is a bit long for the hoppes, 20 minutes is recommended, at $30 ultrasonic cleaner might be worthwhile also: http://www.amazon.com/Professional-Ultrasonic-Jewelry-Eyeglass-Cleaning/dp/B001DKDAVW Bill N84WJ, RV-8, 1097 hrs RV-8.blogspot.com > > 1. 11:22 AM - Cleaning fuel injectors (Charles Brame) > 2. 11:49 AM - Re: Cleaning fuel injectors (vanremog@aol.com) > 3. 02:13 PM - Re: Cleaning fuel injectors () > 4. 03:46 PM - Re: Cleaning fuel injectors (Bill Gill) > 5. 03:51 PM - Re: Cleaning fuel injectors (Lyle Peterson) > 6. 04:59 PM - Re: Cleaning fuel injectors (Charles Kuss) > 7. 04:59 PM - Re: Cleaning fuel injectors (Charles Kuss) > > > ________________________________ Message 1 > _____________________________________ > > > Time: 11:22:20 AM PST US > From: Charles Brame > Subject: RV-List: Cleaning fuel injectors > > > I have an Air Flow Performance fuel injection system on my Lycoming O-320. > The > AFP manual recommends cleaning the fuel injectors every 100 hours.

I have seen admonitions against using volatile solutions like Hoppe's #9 or MEK but no information on what should be used. I use an ultrasonic for cleaning rifle cartridges and the solution is intended for brass but I don't know if it would be ok for injectors. john RV9A On 1/5/2015 8:02 AM, Bill Judge wrote: > Lycoming instructions are here: > http://www.lycoming.com/Portals/0/techpublications/serviceinstructions/SI%201275C%20%2809-23-2008%29/Cleaning%20Fuel%20Injector%20Nozzles.pdf > > I cleaned mine after 1000 hrs of operation and my fuel burn dropped by > 0.5 gph when running lean of peak. > > Gradually they got worse at atomizing the fuel and I wasn't able to > run as lean. > > Its easy enough to do that I'll probably do it at each annual. > > 1 hr is a bit long for the hoppes, 20 minutes is recommended, at $30 > ultrasonic cleaner might be worthwhile also: > http://www.amazon.com/Professional-Ultrasonic-Jewelry-Eyeglass-Cleaning/dp/B001DKDAVW > > Bill > N84WJ, RV-8, 1097 hrs > RV-8.blogspot.com > > ________________________________ Message 3 _____________________________________ Time: 02:42:07 PM PST US Subject: Re: RV-List: Injector Cleaning From: vanremog@aol.com =0AYou might want to give this juice a try.=0A =0Ahttp://www.u ltrasonicsdirect.com/12decacl.html?productid=12decacl&channelid=FROOG=0A =0A =0A =0A-----Original Message-----=0AFrom: John Morgensen =0ATo: rv-list =0ASent: Mon, Jan 5, 2015 11:07 am=0ASubject: Re: RV-List: Injector Cleaning=0A=0A=0A =0A Any idea on a recommended solut ion to use in an ultrasonic?
