Nitroholic Posted August 1, 2014 Share Posted August 1, 2014 First question..... are you using a remote third channel type killswitch? if not....you should! But that's another issue. Try unplugging your killswitch and checking it. If you have a multimeter, you can easily check with continuity ( resistance ) if it is working. When you press the button, it connects the + and - and shorts the coil, so no spark. If you can't check it properly...you could try unplugging the killswitch. DO NOT RUN YOUR ENGINE LIKE THAT. Take the spark plug out, pop it back into the plug cap and hold the electrode against the metal of the cylinder head. See if you have a spark, If so...your killswitch is stuck in the 'kill' position. Assuming your plug is Ok and your coil gapped correctly on the flywheel, then you should get a spark. Only other thing to check is the plug cap. The spark is generated by the magnet on the flywheel. This magnet spinning generates the low ension voltage, which the coil turns into the spark. Not a lot to go wrong with that system. 1 Quote Link to comment Share on other sites More sharing options...

chrisknights Posted August 1, 2014 Share Posted August 1, 2014 have you checked your breather hole on your fuel cap to see if its blocked as that can cause fuel not getting to the carb , best way to check is to undo the fuel cap and prime the fuel Quote Link to comment Share on other sites More sharing options...
seanSOUTHEND Posted August 1, 2014 Author Share Posted August 1, 2014 im getting fuel in the top where i push it down but thats as far as it gets, if i put fuel down the hole for spark then start it it will run for a sec or 2 .. so just orderd new carb . fingers crossed Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted August 1, 2014 Share Posted August 1, 2014 Have you got the fuel pipes on the right way round? Common mistake. Fuel goes in the bottom and out the top Quote Link to comment Share on other sites More sharing options...
