GazW Posted March 11, 2012 Share Posted March 11, 2012 Does it turn over on the button? If it just clicks I would check the starter relay, if nothing happens check fuses and switchgear. If it turns over but won't fire I would change the pilot jet. Have a look at your spark plug. Is it white and blistered? If it is you are running too lean. Why did you change the carb in the first place? Was your old one knackered? I don't really see much of an advantage on a 50 Quote Link to comment Share on other sites More sharing options...
Guest Posted March 11, 2012 Share Posted March 11, 2012 your right there why did i change it i do not no, i put the normal one back on now but with the same jets and pilot jet i think is that the little 1 next to the main jet ? and it still will not start button just clicks but i have to bump it anyway but i took spark plug out and that is a nice darkish brown colour i put a little petrol in head and it started for 1 second but i think it just makes it sound like it was started but just wont start ???

rushwind Posted March 11, 2012 Share Posted March 11, 2012 first check your battery, sounds like it has not enough power to turn the starter fast enough,if it has low charge......(guess what?,,,,,,,,,,charge it up!!!)thensee if it is charging?, should be over 13.5 volts or so across the battery terminals with the engine running, if that is okthen think about carbs??

Fozzie Posted March 12, 2012 Share Posted March 12, 2012 I had one of these, had plenty of problems with it If its clicking on the starter you have a duff battery and should replace it.Are you starting it with the choke on? It always needed a bit even in summer otherwise it would die after a few seconds.Explain how it rides more clearly? Does it idle then pull away fine and bog down or does it do it when given even a bit too much throttle? Quote Link to comment Share on other sites More sharing options...
