charlieemc Posted May 17, 2016 Share Posted May 17, 2016 Hello again lol, i ran my car today at it lasted 12 seconds of driving around until it stalled and stoped. I tried to start it again it wont, i'v - Charged glow starter - checked for leaks - primed the engine - factory needle settings - changed the glow plug to a new one. NOTHING WILL WORK Quote Link to comment Share on other sites More sharing options...
behappy2755 Posted May 17, 2016 Share Posted May 17, 2016 Heat the engine up, with a heat gun or hair dryer, and prime properly (make sure the fuel tank is full and that fuel is flowing down the line). Then give it an extra 5 pulls without covering the exhaust. Open the idle gap, and attempt to start it with a few quick pulls. Is your fuel fresh? Does the glow plug actually glow when you take it out? Quote Link to comment Share on other sites More sharing options...

Ian w Posted May 17, 2016 Share Posted May 17, 2016 Take the plug out, check if the end has got fuel on it if it is dry means no fuel is getting thro` means a blockage somewhere, if it is wet could be flooded turn car upside down with plug out pull pullstart a few times put plug back in don`t prime to much and try to start again. Make sure your glow plug is O/K. Quote Link to comment Share on other sites More sharing options...
locky Posted May 17, 2016 Share Posted May 17, 2016 1. Take glow plug out and put in glow igniter to make sure it is glowing nice and hot. 2. Make sure fuel is getting into engine, see it move through the lines as you crank engine. 3. Increase idle rpm using the transmitter trim. 4. Lean LSN a little. 5. If flooded remove glow plug and turn engine over. Quote Link to comment Share on other sites More sharing options...

dazp1976 Posted May 17, 2016 Share Posted May 17, 2016 Could the con-rod have gone? Or Ran it too lean and it's gave up? Carb blockage? Did you see what temperature it was at when it stopped? Quote Link to comment Share on other sites More sharing options...

behappy2755 Posted May 17, 2016 Share Posted May 17, 2016 Maybe the one way bearing has failed and your starter thing isn't turning the engine? Quote Link to comment Share on other sites More sharing options...
charlieemc Posted May 18, 2016 Author Share Posted May 18, 2016 when the roto starter is trying to start it and engine cooler block that connects to the engine, there is a tiny gap and smoke comes out of there, the screws are not crossed, and fuel is spitting out from the same spot... no idea -/- Quote Link to comment Share on other sites More sharing options...
locky Posted May 18, 2016 Share Posted May 18, 2016 So you think there is a leak from the seal between the cooling head and the engine, possibly either cooling head or glow plug seal issue. Remove the 4 screws and cooling head and check surfaces are clean, check the screws tighten up in the engine and are not stripped, either screws or thread. Check seal between glow plug washer condition and cooling head surfaces. Replace cooling head and make sure it sits flat/square on engine and hand tighten screws. 1 Quote Link to comment Share on other sites More sharing options...

dazp1976 Posted May 19, 2016 Share Posted May 19, 2016 (edited) The only time I've had fuel coming from between the head and crankcase was when the fuel was under too much pressure. I'd forgot to open an air vent on the heli when I filled it and that caused pressurized fuel which then peed out from between the 2 while running. I have clip thingy's on the intakes to stop dirt ingress when not in use and forgot to unlock them. Can't see how that could happen on a car tho??
