topgearmad92 Posted January 27, 2008 Share Posted January 27, 2008 Hi, I have an HBX VRX-2 PRO (Nitrotek) buggy, this is my first car as I am new to this hobby. I am having problems with the glow plugs & would like some advice. I seem to get through a glow plug every time I take it out, I know these are unpredictable things & can fail at any time but this much? Can anyone tell me if this an indication of another probem, hot engine etc or am I just unlucky. Which is the best make to buy? thanks Quote Link to comment Share on other sites More sharing options...
Mr Terminator Posted January 27, 2008 Share Posted January 27, 2008 It can be a problem when the mixture is too lean or too rich but more when the mixture is too lean unless your breaking the engine in.The best plugs in my opinion for handling an overlean mixture are McCoy MC-9's also OS 8s are good too.... Try either as the GO.21 engine thats in the VRX-2 are a good performer.. Quote Link to comment Share on other sites More sharing options...
ziggy12345 Posted January 28, 2008 Share Posted January 28, 2008 Check the temp of the engine. It usually means its too hot. Try richening the engine. Another problem is too much compression but as your new to this I dont think you have messed with the head shims Cheers Quote Link to comment Share on other sites More sharing options...

Which is the best make to buy? thanks Be very carefull, have you just got it or have you had it a while? reason being the factory settings on the carb are well out for some reason, i got my youngun one and it was a mile out on the LSN side so my guess would be your running very lean and hence the glow plug a run scenario and your on your way to a early blown engine , i'd either set the LSN needle to run a bit richer yourself or if you aren't to keen get it to your local LHS and get them to adjust it for you Quote Link to comment Share on other sites More sharing options...

The LSN seems to be ok, when stopping with the pinch method it runs a couple of seconds, sometimes revs slightly & then stops. If I increase the tickover the car starts to creep forward so I think I have this about right. Quote Link to comment Share on other sites More sharing options...
The_One Posted January 28, 2008 Share Posted January 28, 2008 must be running very hot then if your burning glow plugs, like ziggy as posted try richening it up a bit and see if that cures the problem Quote Link to comment Share on other sites More sharing options...
