mista majestic Posted July 22, 2024 Share Posted July 22, 2024 Hi all I have a weird issue with my new car - it was a bit of a pig to get started but I managed to let the first tank sing through with a small tweak of the idle speed. I have tried to re-start for the second tank but it just bogs down and dies after 6 seconds or so once the glow starter is removed. What is also odd is that when the glow plug starter is removed it dies immediately once I turn the hand receiver power on. It will operate and I can blip the throttle a little only when the glow plug charger is still on the glow plug. Am i doing something dumb?! cheers Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted July 22, 2024 Share Posted July 22, 2024 sounds like the glow plug is fouled or dieing running in is hard on the glowplugs you could try changing the glowplug see if that helps 1 Quote Link to comment Share on other sites More sharing options...
locky Posted July 22, 2024 Share Posted July 22, 2024 Lean the HSN as it is probably very rich. If it is a brand new engine then preheating reduces mechanical stress and prolongs engine life. Run it for a tank with wheels off ground and fast idle, with sock on cooling head to keep temps up. Always best to have spare glow plug to swap out and eliminate potential issue. Give it some throttle when starting. Quote Link to comment Share on other sites More sharing options...
Ziggy122 Posted July 22, 2024 Share Posted July 22, 2024 The car will always run with the ignitor when the fuel ration is rich cause the fuel is meant to reheat the plug but when it's super rich (during break it's not uncommon to cool the plug more than heat) Having the heater attached means it's always hot regardless Run in is always the worst time to keep the thing running, don't stress it's a phase you have todo Not uncommon to destroy a few plugs Things I've done in the past to help Pinch the fuel line for 1 second MAX when it's struggling this will allow it to use the excess fuel up before fresh is arriving - and more air in! Upping the idle, often I did it via the remote setting the break in settings on the HSN&LSN but then leaning them out abit again to prevent excessive over fuel - don't go mad tho, it needs to be oily to work Preheating the engine is vital, it aids starting and helps keep things going in the right direction (warming up) I used an old cheap hair drier ziggy Quote Link to comment Share on other sites More sharing options...
mista majestic Posted August 19, 2024 Author Share Posted August 19, 2024 Thanks for this info btw I now have a new problem.. 🙄 I successfully went through a few tanks and gave it some driving.. nothing crazy, all on flat tarmac and not for an extended period of time and all was good. I have gone to try and start the car yesterday but it would not fire into life. The glow plug looks fine.. all shiny and like new inside, and does indeed glow when I’ve inserted it into the starter. No matter how many starts I try there is no hint of it firing into life! It’s a new vehicle, and has gone through around 6 tanks of fuel successfully so far. Nothing seems out of place in terms of tubing etc. Any ideas? Could it simply be pre-warming the engine? It has been fine up until now… TIA Quote Link to comment Share on other sites More sharing options...
Nicholas Jones Posted August 19, 2024 Share Posted August 19, 2024 (edited) Have you: - Primed the engine - Tightened the glow plug - Filled the fuel tank so the fuel is above the outlet - Charged the glow igniter - Returned the tune to factory settings - Checked the compression I know these are basic things, but they can be missed easily. hope this helps 🙂 Edited August 19, 2024 by Nicholas Jones Quote Link to comment Share on other sites More sharing options...
locky Posted August 19, 2024 Share Posted August 19, 2024 Remove air filter, check that fuel is entering carb when priming, leave throttle 1/4 open with electrics off, try starting. Assuming glow plug charger and glow plug all ok, needle and idle settings satisfactory when last run. Preheating mainly helps when breaking in to reduce force required to overcome new engine with high level of pinch, but not always required, however it should prolong engine life.

mista majestic Posted August 19, 2024 Author Share Posted August 19, 2024 Cheers guys I’m presuming the engine is primed ok but you can’t see the fuel in the lines on my car as the tubing is quite thick. The glow lighter works, but I guess there is a chance it’s not forcing enough of a current into the plug, so will investigate that. I will try the air filter removal to see if the fuel is entering the carb for sure with the throttle on a touch.. Thanks 🙏 1 Quote Link to comment Share on other sites More sharing options...
locky Posted August 19, 2024 Share Posted August 19, 2024 The glow plug should glow bright orange with glow starter. What type of battery in the glow starter? If nimh then always best to recharge, as they do self discharge. Quote Link to comment Share on other sites More sharing options...
Nicholas Jones Posted August 19, 2024 Share Posted August 19, 2024 If fuel doesnt come through the carb, de-coke it with some brake/carb cleaner. Just make sure to replace the o-rings afterwards; please don't make the same mistake I did 😅 Quote Link to comment Share on other sites More sharing options...
mista majestic Posted August 22, 2024 Author Share Posted August 22, 2024 Update: if anyone gives a £hit haha.. took everything off, swore at it, cleaned it even though it was fine, chucked it all back together and the mofo started first pull and have been happily ragging it around ever since 1 1 Quote Link to comment Share on other sites More sharing options...
