Default Engine flame out help

All,

I have an orion .21 alpha abi engine and i have run it several times. It is awesome!

However, now for some reason, it is flaming out on me. I was just messing with it in the garage and when i start it up then try to pull the glow plug igniter out, it flames out right away. The plug looks fine.

Any suggestions?

Thanks,

Sounds like you have a bad glow plug even though it looks fine.

First thing I EVER do before anything else is swap glow plug. You should always have a spare anyway.

try a new plug. also there might be fuel biult up in there try to rev it A LITTLE to clear it out. Dont over rev it because it will be cold and you dont want to damage the engine.

That worked.

However, how long should a plug last?

The leaner or richer you run it, the shorter the life span. I find turbo plugs last way longer than regular.

7-8 tanks seem like an awful short glow plug life. That would be 2 dead plugs or more at a single club race. I would check your tune....or buy higher quality plugs (if you're not running them already). Everyone is different, but if your average for a single plug is 7-8 tanks....that's a bit short. If it's an occasional plug dying at 7-8 tanks them your on par with me at least. I typically blow a plug every 2-3 races.

I used to put in a new plug for each race and would use the old ones for practice, but with my plugs lasting more than a gallon on average, I quickly had a bunch of good used plugs in my box.

Buy some O'donnell glow plugs. They seem to last a long time, and are cheaper than most other brands.
