7zark7 Posted September 2, 2005 Posted September 2, 2005 It will get easier. After break in and once its tuned and had a couple of litres through it it will be easy to start. Priming is the big things with these engines, do it right and it will start, get it wrong and you either have nothing in the carb or a cylinder full of fuel. Quote
Josh Posted September 2, 2005 Posted September 2, 2005 Just a question, being new to nitro and waiting for engine, is that fuel pouring outa the exhaust? just so i know what to expect during run in. Cheers Quote
Big T Posted September 2, 2005 Posted September 2, 2005 Yeah it is, it's just that they run so rich on break in the unburnt fuel goes out the exhaust. Nothing to worry about though Quote
dark_shadow Posted September 2, 2005 Author Posted September 2, 2005 I'm actually getting sick of this, the engine only stays running if i knock it at full throttle, engine stops if there is little (near mid) or no throttle. And it pours a load of nitro via the exhaust. I'm seriously in some form of regret Quote
123456 Posted September 3, 2005 Posted September 3, 2005 Wouldn't it be much easier if they came ready broke in? I mean, really? Quote

robbybo Posted September 3, 2005 Posted September 3, 2005 I'm actually getting sick of this, the engine only stays running if i knock it at full throttle, engine stops if there is little (near mid) or no throttle. And it pours a load of nitro via the exhaust. I'm seriously in some form of regret Sorry to hear your having such problems, don't let it get to you though I'm new to this too, I found when I ran mine in it was very easy to flood the engine because the factry needle settings were so rich. when you flood the engine a lot of fuel will go to the exhaust and because of this it seemed to develope more back pressure which in turn pressuresed the fuel tank more and sent even more fuel to the carb, a sort of vicious circle. what I did was to tip the car up and down to get the fuel out of the exhast pipe, removed the glow plug and the fuel tube to the carb and turn the engine over whilst holding a bit of kitchen roll on top of the engine to catch the fuel which will shoot out where the glow plug was. this should clear out the engine. put the glow plug and fuel line back, and try again. Be careful not to flood the engine, and try starting and running at 1/4 throttle. Once you have run it in you can start tuning and it will get easier Rob Quote
7zark7 Posted September 3, 2005 Posted September 3, 2005 Have you contacted mirage yet?? Have a good look at your glow plug (make sure its not black and that the filament glows along the full length) and check your fuel and pressure lines for air leaks. Quote
123456 Posted September 3, 2005 Posted September 3, 2005 Go and take your sarcasm elsewhere Idiot. ← It was a serious question. Why can they not sell them ready broke in? Quote
7zark7 Posted September 3, 2005 Posted September 3, 2005 It was a serious question. Why can they not sell them ready broke in? ← I've often thought that myself, I'm sure theres a technical reason for it though. Quote
Big T Posted September 3, 2005 Posted September 3, 2005 These engines are so mass produced they could never get it done. It's the same with 1:1 cars. It's only on sports cars that they sometimes run them in before leaving the factory. Tony Quote
123456 Posted September 3, 2005 Posted September 3, 2005 I am sure there must be a very good reason, probably on the grounds of practicaility. FInding the space to run in every truck they shipped out would be an [CENSORED]. Quote
dark_shadow Posted September 3, 2005 Author Posted September 3, 2005 It was a serious question. Why can they not sell them ready broke in? ← I apologise for that then. Now It won't start alltogether I'v primed the engine and took all of the precautions I tried before . . . Quote
Big T Posted September 3, 2005 Posted September 3, 2005 I apologise for that then. Now It won't start alltogether I'v primed the engine and took all of the precautions I tried before . . . ← You have checked you glow plug and charger? Quote
dark_shadow Posted September 3, 2005 Author Posted September 3, 2005 You have checked you glow plug and charger? ← How can, I tell if the glow starter is empty? I removed the glow plug and put it in the glow starter and it red . . . Quote
dark_shadow Posted September 3, 2005 Author Posted September 3, 2005 Both are fine then. Is it roto start? ← Nope it's turning fine! Quote
Big T Posted September 3, 2005 Posted September 3, 2005 If it is a roto start give it a blast on a charger just to eliminate that possibility. The roto start doesn't have to die much before it won't kick the engine to life. Thats about the extent of my knowledge so I'll have to let someone else help now. Sorry. Tony Quote
salman Posted September 3, 2005 Posted September 3, 2005 Try come up to Huddersfield if you can! Il sort ya out! Quote

robbybo Posted September 3, 2005 Posted September 3, 2005 Its highly unlikely, but years ago I had a friend who had an HPI style glow plug battery thing, and he couldn't start his car, pulled out the glow plug popped it in the the thing glowed perfect, he nearly went insane couldn't figure out what was wrong, then tried putting the glow plug in the thing and turning it upside down(i.e. the same way it is when on the engine) AH HA there was a loose connection! it didn't glow when upside down! Highly unlikely I know, but it can happen. The glowplug needs to be glowing a sort of bright orange a dull red means the battery is running low. Might be worth charging up all your batteries. check all the needles on the engine are at factory settings Check glow plug check fuel lines for air dirt ect If you are starting the engine on a block (wheels off the ground) don't turn on your TX or RX and set the throttle by moving the servo by hand to no less than 1/4 open. Once it starts you can reduce this by hand. I have found they don't like starting on tick over. u need to be really organised with your kit everything to hand, and think about what your doing carefully What fuel are u using? Rob Quote
dazzi220 Posted September 3, 2005 Posted September 3, 2005 set the hsn to 4 turns out(anti clockwise) from fully closed(turned clocwise as far as it can), carb at 2mm with an empty tank remove the gplug prime it and turn it over keep doin until theres no fuel in the engine at all - bone dry, tip it upside down to see if any fuel drips out theres nothing wrong, you've flooded it Quote
dark_shadow Posted September 3, 2005 Author Posted September 3, 2005 Right, took the glow plug out and tipped it over and started the rotostart, no fuel came out :S Here's a *Video* after I did that and replaced the glow plug Quote
123456 Posted September 3, 2005 Posted September 3, 2005 Give a little throttle on the radio when you are trying to roto start it up. If it is not priming properly you can flick the oil filter off, drop a little fuel into the carb, then fire it up. HAd to do that a few times when I was breaking my engine in. Quote
robbybo Posted September 3, 2005 Posted September 3, 2005 (edited) is there fuel in the fuel line leadin to the carb? its hard to see, if there isn't you need to hold finger over exhaust and give it a tiny blast with roto until fuel has reached carb. Make sure your glow plug heater is giving a good orange glow too as they don't start well when there not glowing well Rob Edited September 3, 2005 by robbybo Quote
