HYPER-BOY Posted November 3, 2013 Share Posted November 3, 2013 Took the Baja out today, choke open, pull pull fire. Choke closed pull pull started, ran for 10 mins, going great.. Running on wet grass but the car itself wasn't soaking really. Then Burrrrrrrrrrrrrrrrrrrrrrr cut out. Tried to start it since and nothing.. Took off the spark plug and seems a decent spark, tried another plug and nothing. So took the kill switch off the main power cut switch and nothing. Could it be that the carb is set too rich, fouling the plug? I've had the carb apart and all looks ok, still can't get it to fire! Had the whole thing apart but noooo good. I'm annoyed and feeling down about it. Only had it a day Any help? Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted November 3, 2013 Share Posted November 3, 2013 Pop the plug out and have a look...the colour of the electrode will tell you a lot about how it was running. Also worth checking too see where the carb is, and re-setting to stock settings if in any doubt. Quote Link to comment Share on other sites More sharing options...
HYPER-BOY Posted November 3, 2013 Author Share Posted November 3, 2013 I've set the carb to 2 turns out hsn and 1.5 lsn, no fire. I've cleaned the plug too, does look a little fouled. Seems there's a fuel issue cus I pull about 15 times, take plug out turn upside down and pull the starter and nothing comes out.. Any other ideas?

swingy_p Posted November 3, 2013 Share Posted November 3, 2013 fuel lines the correct way round on your carb? does the primer bulb fill when pressed? Quote Link to comment Share on other sites More sharing options...
Sphinx Posted November 3, 2013 Share Posted November 3, 2013 Also did you check that the foam on the air filter was not soaked, did you reoil after ? Gav Quote Link to comment Share on other sites More sharing options...
HYPER-BOY Posted November 3, 2013 Author Share Posted November 3, 2013 New plug Tried a plug from a relatively new 1/5 scale and no firing. Quote Link to comment Share on other sites More sharing options...
HYPER-BOY Posted November 3, 2013 Author Share Posted November 3, 2013 fuel lines the correct way round on your carb? does the primer bulb fill when pressed? Yeah it fills no problem, it was running for 10 mins then died. Also I notice the filter seems as though it has fuel on it.. Quote Link to comment Share on other sites More sharing options...

swingy_p Posted November 3, 2013 Share Posted November 3, 2013 sounds like its flooding for some reason as filter shouldnt be getting soaked with fuel Quote Link to comment Share on other sites More sharing options...
HYPER-BOY Posted November 3, 2013 Author Share Posted November 3, 2013 sounds like its flooding for some reason as filter shouldnt be getting soaked with fuel Yeah was thinking that, but wondering why it isn't pulling it into the engine.

Sphinx Posted November 3, 2013 Share Posted November 3, 2013 Take the spark plug out, tip up side down, pull the pull start 10 times, the put the spark plug back in, reset the H/L needles and then reprime and it should be fine. Gav Quote Link to comment Share on other sites More sharing options...

Gav Hi mate I have done exactly what you said and still no good.. Maybe a blockage in the carb? Quote Link to comment Share on other sites More sharing options...
Sphinx Posted November 3, 2013 Share Posted November 3, 2013 Ok, take the carb out. Open the butterfly and blow with your mouth and see if any crud is in there, the blow in to the in and out pipe for the fuel. The only other thing i can think of is the rubbish fuel mixture, maybe be worth making a new mix. What mix do you have ? Gav Quote Link to comment Share on other sites More sharing options...
goldman Posted November 3, 2013 Share Posted November 3, 2013 Check vent hole in petrol tank cap,maybe blocked. Goldman Quote Link to comment Share on other sites More sharing options...

Gav I'll try that tomorrow, was thinking it may be the mix, if it was too much oil in there would that stop it firing? - I will take all the fuel, flush and try a new 25/1 mix. I didn't fuel it mate, it had a full tank when I picked it up! Quote Link to comment Share on other sites More sharing options...
Sphinx Posted November 3, 2013 Share Posted November 3, 2013 Not really, to much out will make it run like a bag of wind. To little oil with seaze the engine. Gav Quote Link to comment Share on other sites More sharing options...

Sphinx Posted November 3, 2013 Share Posted November 3, 2013 Don't worry, it's not the engine as you have tried to start it, if it was seazed it would not move the piston. I thing it's just a fuel problem. Gav Quote Link to comment Share on other sites More sharing options...
goldman Posted November 3, 2013 Share Posted November 3, 2013 Are all the gaskets on the carb back on the rignt way,some have holes in that need to line up on carb body. Goldman Quote Link to comment Share on other sites More sharing options...
