rcmatt Posted February 7, 2008 Share Posted February 7, 2008 normally starts easy and runs well but left it at a friends and now it wont start.He sais the exhaust came loose,when he tightend it and re started it was reving high and moving forward.Instead of adjusting the LSN he messed about with the idle screw and throttle trim on the handset.Now it wont start,its not flooded and ive got a spark,ive tried the idle screw in diffrent positions but no luck. please Quote Link to comment Share on other sites More sharing options...
martin34 Posted February 7, 2008 Share Posted February 7, 2008 I would put it back to factory settings and try that if you already havent? Quote Link to comment Share on other sites More sharing options...
rcmatt Posted February 7, 2008 Author Share Posted February 7, 2008 I would put it back to factory settings and try that if you already havent? The high and low speed haven't been moved from factory settings,only the idle,dont no if theres a factory setting for it.can't think what else it could be Quote Link to comment Share on other sites More sharing options...
martin34 Posted February 7, 2008 Share Posted February 7, 2008 The factory settings are 1 and a half turns out on the high speed and 1 and quauter out on low speed.The high speed is the one on the left as you look at it and the low to the right of it.I would put the needles to this just incase your mate messed with them without saying so.

fifthaphid Posted February 7, 2008 Share Posted February 7, 2008 Hi ya Matt. I would leave tick over adjustment alone till its running or you wont have a clue where it needs to be set. If the carb settings haven't been touched then just stick a new plug in it. My marder wouldn't start but when i pulled out the plug it would spark. You see when a spark plug is in the bore and under compression they act differently and you may find this is the case with yours. Any engine will start if it has fuel, spark and compression. Good luck with it and let me know how you get on. Paul. Quote Link to comment Share on other sites More sharing options...

bmw nut Posted February 10, 2008 Share Posted February 10, 2008 have you checked the carb bowl is clean and needle jets are clear? petrol engines dont really require retuning all the time like nitro Quote Link to comment Share on other sites More sharing options...

Sneaker Posted February 10, 2008 Share Posted February 10, 2008 Been having the same problem with my Baja. Normal starts very easy but today just will not. I am sure it is a problem with the carburetor settings, but have given up for today with it. <_< Quote Link to comment Share on other sites More sharing options...
