neal Posted August 11, 2012 Share Posted August 11, 2012 You should always have a light trail of blue smoke from the exhaust.If it is still spitting fuel from the exhaust then you are probably running to rich,start leaning it out with 1/8 turns clockwise on the HSN.

geordierc Posted August 11, 2012 Author Share Posted August 11, 2012 How hard wi it then be to re tune the engine with the higher nitro %age Quote Link to comment Share on other sites More sharing options...
neal Posted August 12, 2012 Share Posted August 12, 2012 Shouldn't be difficult.If the car is running on the settings you have now then it should be ok when you add the new fuel. Just keep an eye on your temps. Quote Link to comment Share on other sites More sharing options...

Englishmastiff Posted August 15, 2012 Share Posted August 15, 2012 Hi Geordierc, Did you get anywhere with your car, I have just got a Hyper 7, similar problem. I got it going but only ran for 10 mins then cut out. I can't get it started again now. I have checked the glow plug which is fine? Any ideas?

Any 1 no of cheap places to buy os8 plugs ang fule from You need to 'prime' the fuel - this is either a primer bulb in the fuel tank, a fuel filter with bulb on it, or simply by covering the exhaust as you try starting. Do this with the glow igniter on the plug and once it kicks, DO NOT prime anymore. If you try too hard you'll flood the engine - simply remove the plug, invert and turn over the engine with the rotostart or pullstart a few times. I do suggest you check the plug first - remove it and place it as you would normally on the igniter and see if it glows - may need replacing. Al.

geordierc Posted August 17, 2012 Author Share Posted August 17, 2012 I have had no tym but hopefully will get it out today if thr weather stays nice i have some os8 plugs and 20% fuel coming today will try tuneing see how it goes will the new plugs sort the problem of stalling when the igniter is removed Quote Link to comment Share on other sites More sharing options...
