Glo Plugs -Please help!

[Paullanzarotti]

I have an Inferno MP7.5 RTR that I have broken in and run maybe 10 tanks through already.

I was told to upgrade my fuel to HJ Nicholls & Son 20% fuel. In the last 2 days I have burnt through 8 glo plugs?!?!

I used 5 on my last tank of fuel!

Does anybody no why these glo plug are failing within minutes? The hobby store I use (308 in Holloway, London) are reputable but there seems to be something seriously wrong.

Does anyone know this fuel? Is this likely to be a fuel issue, a glo plug issue or both?

Please help!?

In what way are the plugs failing?

Is your glow igniter voltage < 1.5v?

Do you have the right number of shims under your head button (compression too high)?

The engine is totally factory so I shouldn't have to adjust the shims. The plugs are dying on me. I run the car for 5 mins and then it dies. I try to re-start and it doesn't so I take out the plug and attach to a glo starter. When the plug doesn't glow I know it's dead. Put a new one in - some fuel and I'm away....for another 5 mins.

I'm new to Nitro and have only been indulging for two weeks but honestly - it's been an absolute nightmare! :arrr:

Exactly what does the coil look like when it's dead. This would be a clue to the problem.

 

[Paullanzarotti]

it looks kinda oily. not black....kinda oliy and brown.

Check out this link.

For starters, it sounds like you're running rich.

Thanks for the link. I don't think the oil on the plug wasa running rich problem because before I take the plug out I try to start the engine. This pumps fuel into thus making the the plug look oily. It's ve strange. Will experiment with different plugs.
