I am NEW to Glow.....how often are glow plugs changed?

When the are burned out.



Yes, that sounds like a smart allec answer. But it's really hard to say. I've had plugs burn out in 10 seconds, and then I've had plugs that have lasted 4+ years (I say plus because it's still running). There are a lot of factors that are involved in it. If you run your engine rich the plugs will usually last a long time, but a lean run can lead to a short plug life. Also, new engines tend to go through plugs quickly. This is because the metal from the engine breaking in will burn out a plug quickly.

Hope this helps some.

Thanks...I just wanted to get an idea so I have my flight box ready with an extra plug. I had a cox engine when i was a kid and i remember that thing needing a new plug frequently.

I always try to have at least 2 or 3 of each type of plug I use on hand in my box. If you don't Murphy will step up and get you. If you have no spares you can assure that you're going to blow a plug out. But if you have extras in your box they will last forever!!!!!

If you use a power panel you may burn them out faster because it's easier to apply too much voltage. If you use a clip-on glow igniter and don't run too lean you can usually run a long time. Exceptions to every rule though.

Thanks guys....one more question ...well before the 50 others - If i have a rechargable glow starter.....is it even worth it for me to use a power panel to power a power starter? Or should I just connect right to battery? If so....I cant seem to find a tote box without the panel cutout.

It would give you a convenient point to plug in the electric starter. A place to control your elec fuel pump if you have one. A place to recharge your 12 volt battery. Some panels have a connector you can sttach your glow ignitor to recharge it (handy). A place to connect back-up glow cables for stuborn engines.

If no panel, you can fabricate a blank plate to cover the hole.

Thanks bruce.

Well, I ordered 2 extras and received 24. I guess the plug in my engine now will last forever.

OH SO TRUE!

I like the rechargable glow starter, better then having a cord close to the prop.
For glow plugs I use only one kind OS type F, then again I run only four strokes.
