Do you have your EIS set for centigrade or Fahrenhe it? The most common cause for the disfigurement of spark-plug base rings is over - torque of spark plugs. I was surprised to find out that my engine ( 40hp H irth 2702 ) only requires 108 inch pounds ( yes, inch pounds) of torque and w ith the spark-plugs seal ring installed with no anti- sieze compound.

It's sometimes hard to see the fuel in the tube. I thought of adding a small ball float in the tube for visibility. I know J3's use a cork on the bottom of a wire for fuel level. Don't know if it is coated or sealed with anything? Any ideas from the group on what to use? Obviously must be compatible with fuel.

Don't know if it is coated or sealed with anything? Any ideas from the group on what to use? Obviously must be compatible with fuel. It's been done, so you wouldn't be the 1st. You do need to be sure it can't hang up in the tube, block the fuel's movement in the tube, or *escape the tube*. Depending on how the system is plumbed, you could block the fuel vent, give yourself a false fuel level reading, or even block fuel flow (if it escaped the tube). --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 5 _____________________________________ Time: 02:20:45 PM PST US Subject: Kolb-List: Re: Fuel level indicator From: "Richard Pike" This guy has an interesting idea - the pattern behind the tubing changes shape depending on whether there is fuel in front of it. http://mybearhawkpatrol.com/finish/fuelsight.html Or you could just go with this: http://www.univair.com/piper/piper-pa-11/view-all/u10853-000-piper-fuel-gauge-float-ball/ -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.
