I just started my Evo gasser for the first time and after a few minutes I noticed that the fuel line was begining to abrade against the
engine.

My past experience with glow engines I never had this problem. Am going to try and shorten the line and route the excess away from rubbing the engine. Will also slip a section of hose around the line to protect.

Any thoughts...

Thanks

keep fuel lines clear from the engine at all times if possible. That applies to glow engines as well, but for gas engines in particular, since they run hotter. Angle the tank outlet a bit and you can run a straight line. Keep well away from that exhaust manifold as well, unless you want a bag of problems.

All that you have suggested will work as from from the pictures you posted it's obvious that the fuel tubing is simply too long and will in fact rub against the ignition's braided HT lead. Just shorten and relocate their run if possible to avioid them touching.

Also use some method of securing the tubing at the connections otherwise they will slip off eventually. A simple fix is to use small nylon ties or better still suitable size fuel barbs are available which are soldered to the brass tubing and with the ties provide a much more secure fix.

Thanks

I shortened the line and have a small tie wrap to run it along the plug wire looks better now.

Do they make hose clamps small enough to go over the tygon fuel line?

I'll look for those barb fittings also

cut off a small ring of fuel line, and use that as a clamp by slipping it over the remaining line end.

Yes they do but I have never had much luck in using them on gas lines as after a while the tubing hardens and the clamps lose most of their holding power. They work very well for glow.

<i>cut off a small ring of fuel line, and use that as a clamp by slipping it over the remaining line end</i>

easy for you to say..

Sounds like a great idea if ai can find the tubing with the right ID

You take a piece of the original fuel line, cut a 1/4"wide section off. slip that onto the beaks of a pointed plier, open the plier beaks thus stretching the ring, and slip the fuel line end in. pull out the plier. Easier done than said!

just wondering what is the black wire running to your spark plug?I have the same eng and I don't have it? How do you like the dubro mount?

That is the wire from the electronic unit the ground I believe.

The Dubro mount is good. I bought the radial mount but liked the Dubro better

Heres what the rest of the plane looks like. I can't wait to get this plane in the air, the way it was pulling on the starting bench when I gave it its first test run was incredible.

Trying to get a battery now for the ignition that works. This engine's ignition needs to stay above a certain voltage or it cuts out. Mine ran for 7 minutes yesterday and then quit, Charged the battery and tried again went for 7 minutes and quit, Now I need to find a 7.2 volt with enough milliamp for the task. Anyone out there Use lithium ion batteries?

Pe- I've found that forceps work better for this.

English being not my native tongue, I use round nose pliers that spread when I squeeze! The type to expand a bearing lock spring ring.
Forceps, is that tweezers? It's late now, and I have no energy left to look it up! [&o]

Its all a mute point right now as I can not get this engine to even run....

[:@] very aggravating

ahhhh got it runnin just need to gassit up more

going to run an 18 X 6 Mejzlik prop on it. this should be some flyer when I finally get it to the field.

Now off to find some forcep/ pliers.......

Pe,

Snap ring pliers is the name you are looking for I believe.

Fritz, I use a 2 cell lithium Ion battery (7.4, 1800 mah) and it works great.

Thanks thats great to hear. I just ordered one from Maxx Products

They sound a little safer due to the fact they have an internal fuse of sorts
