bobsomebody Posted January 27, 2008 Share Posted January 27, 2008 had my car going fine yesterday, after putting some new parts on [shock springs etc] but today no matter how hard I tried it wouldnt even try and start. Engine is primed properly and all batteries charged. The engine was warmed by a hair dryer. What could it be? I tried pushing the throttle out a bit but still nothing. Checked glow plug, it was fine. Any help would be good. Quote Link to comment Share on other sites More sharing options...
Dazzle Posted January 27, 2008 Share Posted January 27, 2008 Hi, have you taken off the air filter and made sure there is a 1-1.5mm gap in the carb ?? Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted January 27, 2008 Author Share Posted January 27, 2008 yes, there is. Im stumped by it all. Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted January 27, 2008 Author Share Posted January 27, 2008 ok, I managed to get it going but to keep it going I have to manually pump the fuel in with my fuel primer pump. Maybe a blockage? It sounds dead croaky also...any ideas? Quote Link to comment Share on other sites More sharing options...
ben_rc Posted January 27, 2008 Share Posted January 27, 2008 Yes could be a blockage, but don't quote me on that Quote Link to comment Share on other sites More sharing options...
Dazzle Posted January 27, 2008 Share Posted January 27, 2008 check the pipe that goes from the exaust to the fuel tank, this is what keeps the pressure in the tank forcing fuel into the carb. hope it helps Dazza Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted January 27, 2008 Author Share Posted January 27, 2008 will do it tomorrow morning. I have spent 4 days out of the last week messing about trying to get the thing running smooth and just when I think I have it , it plays up. Not had 1 day of running it properly in a few weeks-its beginning to **** me off! Quote Link to comment Share on other sites More sharing options...
boze Posted January 27, 2008 Share Posted January 27, 2008 If you have an inline fuel filter then, providing your tanks not full of crap, take it off. Quite a few people have had problems with them. Damo Quote Link to comment Share on other sites More sharing options...
Switch Posted January 28, 2008 Share Posted January 28, 2008 just when I think I have it , it plays up. Not had 1 day of running it properly in a few weeks-its beginning to **** me off! Know THAT feeling very well. If you have an inline fuel filter then, providing your tanks not full of crap, take it off. Quite a few people have had problems with them. Damo May try this myself, just to get the thing to keep a tune. Quote Link to comment Share on other sites More sharing options...
Indie Posted January 28, 2008 Share Posted January 28, 2008 I think the problem with a lot of people who are tunning the car and then wondering why it won't start the next time is they are tuning the Engine whilst it's warm. Try getting the Engine all tuned and then richen 1/8th of a turn you won't loose any performance and it should be easy to start next time you go to start the Engine. Also once you have these two set in place and stopped running the car I'd take the air filter off and adjust the idle to the 0.5mm to 1mm gap again in the carb as it may be larger or smaller after the tuning, Dunno if this helps anyone just thought it might be useful Chris Quote Link to comment Share on other sites More sharing options...
Danny-B- Posted January 28, 2008 Share Posted January 28, 2008 How much tuning have you done to it ? it sounds like its off tune. Croaky could be too rich but if you adjusted the settings too much its gonna be a nightmare to get running right, might be worth resetting the needles to base setings then lean both needles 1/16th, then retune from there.

bobsomebody Posted January 28, 2008 Author Share Posted January 28, 2008 it was and has been fully tuned for about 3 weeks now. I was going to lean the LSN out once I got it going but still not had any luck. I had it running perfectly. Quote Link to comment Share on other sites More sharing options...
Zizzle77 Posted January 28, 2008 Share Posted January 28, 2008 Pull the fuel pipe off the exhaust and the carb, direct the pipe away from the car and blow down the exhaust end of the pipe to make sure the fuel is flowing easily. Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 ok, update if anyone cares. Got it started today no problem but it seems to have a mind of its own. Starts up then idles for a second or 2 then suddenly kicks in almost full throttle and when I adjust the trim it calms down a bit then speeds up on its own!! Its like its auto adjusting to have full throttle! Im so over it now, its been so long since it worked Im pretty close to just selling it so if anyone has any tips as Im completely stumped and having a car that doesnt respond to my controller is a bit daunting. cheers Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted February 1, 2008 Share Posted February 1, 2008 sounds like a air leak Quote Link to comment Share on other sites More sharing options...
smithy1135 Posted February 1, 2008 Share Posted February 1, 2008 try disconnecting the throttle linkage and hold the carb closed and see if it still has a mind of its own Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 taking it out now and will try that. Let you know later the results. Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 ok the saga continues... I got it started and managed to fight it from zooming off by adjusting trim. I let it idle for a couple of mins to see if it would go mad and it did after a minute then calmed down after I tweaked the trim again, it then cut out so started up again no probs. Idled until it settled then drove it around really slow because Im scared it might shoot off with its unusual behaviour. Ran it until tank empty then filled up started again and it went in reverse!! What the hell!! So I stopped it and re-started and it was ok. So confusing. Any ideas? I ran 2 tanks through it and it seemed to clear out a bit and was running ok-ish apart from this reverse thing.

Thunderwolf Posted February 1, 2008 Share Posted February 1, 2008 oil in your one way bearing (OWB), simply take the pullstart off (carful on the bobbin, make sure it don't come out), followed by the back plate (there is a washer behind this), you will then have a fan type thing in side (the OWB), simply put some tissue, or cotton wool buds around it to clean it up, and do the same for the small shaft that goes into it, then put it all back together. basicly because of the oil the OWB can slip, and now and then the engine will back fire on starting, making the engine spin in the wrong way, causing the car to go in reverse.

bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 ok, I think next time I take it out [not for a week or so due to work] I will see what its upto. I have a sneaky idea that the strange throttle behaviour is due to the transmitter or the LSN being too rich as it was very boggy. Next time it goes backwards I will take it apart and have a tinkle, thing is I just put a roto start on-will this have any effect?Thanks for your help guys.

bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 I think the fuel Im using is rubbish also. Model mechanics I think-its sooooo oily-I reckon I might get some Tornado as thats what I used to use and it never caused trouble. Quote Link to comment Share on other sites More sharing options...
Hyperhuggy Posted February 1, 2008 Share Posted February 1, 2008 Model mechanics I think-its sooooo oily Model Technics ? yeah its poop. I always use Tornado and have had great results with it, although some people rubbish it. Quote Link to comment Share on other sites More sharing options...
bobsomebody Posted February 1, 2008 Author Share Posted February 1, 2008 Model Technics ? yeah its poop. I always use Tornado and have had great results with it, although some people rubbish it. Thats the one! Its soooo oily. Tornado all the way I think. Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted February 1, 2008 Share Posted February 1, 2008 hyper engines ain't too fond of tornado fuel, mine started to rust up even with after run, so i don't like it anymore. roto or oully, can still run the wrong way, won't do it with a starter box though Quote Link to comment Share on other sites More sharing options...
