    Glow Plug Recommendations

    I've Benin running the stock Traxxas glow plugs and have been through 4 in the last month. I haven't even put 1 gallon through yet. Any better glow plugs? Am I doing something wrong? I'm tuned to lean then richer it up slightly.

    I would try re tuning first. Check engine temps, and smoke trail as well.

    What does burning through glow plugs typically mean? Too lean? Too rich? Too hot?

    Depends on what the plug looks like. Most of the time it is due to lean issues.

    The plug is actually clean. There is no visible discoloration, burn, etc. It basically looks brand new.

    Put a glow starter on the plug while it is out, and look at the coil to see if it burns white hot over all the length of the coil.

    Ok, I lied. I looked at the last one I threw out and it was black on the bottom. And I took it out and it doesn't glow at all.

    Also, I have no idea how to get an image to show up in the thread without posting the link to flikr.

    Have you checked the engine to make sure it is sealed from air leaks.
    Worth a try?

    I always set my carburetor back to factory settings and retune. I once blew a few glow plugs with my mixture a little too rich, but the most common would be a lean condition.

    Ok. I feel like I had a good tune. I MIGHT have been running it too lean.

    I KNOW that location, weather, altitude, etc., have an effect on tuning. But about how many turns in do you say the HSN should be from factory settings? Do you guys end up 1 turn lean from factory setting? 1/2 Turn from factory setting? Just to give me an idea. I'm still learning how to "listen" for the tune. Again, I realize one setting in FL will not be the same setting for me in AZ.

    I am about half to three quarters of a turn Max on the HSN.

    Jus to clarify - you are 1/2 to 3/4 turn leaned from the Traxxas factory setting? I just checked my setting and I was about 1 full turn from factory setting on HSN.

    I was just putting around and richened it out. I also re-tested the LSN and that was way lean. I know the manual says to pinch the line and it should shut off in 3 seconds. Mine was like 1.5 - 2 seconds so I richened that. I was having a lot of fuel/oil spitting out of the pipe so I would assume I was rich?

    Although its frustrating, that's why I love this hobby because it takes tinkering!
