Hardrive Posted October 2, 2008 Share Posted October 2, 2008 Dont know if this will help you but I have an sr 125 and found the best way to start it from cold is to pull out the choke all the way and give the throtle a slight twist as you start it. mine wont start unless I give it a slight twist of the throtle. you could check your jets to make sure they are clean its quite an easy job to do and well worth doing. there is a post on here from me about carb probs i had and there is a link to a video of a very similar carb and how to strip down.... p.s.

psbresner Posted October 3, 2008 Share Posted October 3, 2008 I have a similar problem with my SR125, it will only start with a little throttle. Does this even when warmed up. Runs fine once started thou. Paul. Link to comment Share on other sites More sharing options...
qtws Posted October 7, 2008 Share Posted October 7, 2008 Umm... sounds familiar. Look for one of my posts on Sr125 carb - it details the settings I used after a carb strip and clean. >the start ticks over and occasionally it attemp to fire, i have tried using the choke and also adjusting the ide revs but with no luck. Had exactly the same problem with old stale petrol - get some fresh stuff in there! Your idle speed setting could be a bit low, or the pilot screw incorrect. Check petrol tap, fuel level in tank, make sure there's no rusty crap in the tank (if there is, get an inline fuel filter - just cut an inch of pipe out of the fuel line and insert the filter in its place). These carbs are dead easy to strip -might be worth a try if there's any chance something cruddy has got past the fuel tap. HTH, Nigel Link to comment Share on other sites More sharing options...
