Wessie34 Posted March 26, 2016 Share Posted March 26, 2016 The DT (175mx) has had a rebuild, (crank, piston etc) and ran fine for about half hour then lost power a bit and struggled to accelerate, I ran it like that for a few minutes so don't think it was mechanical, seizing etc. Anyway, checked the plug, OK, so had it out today (20mins) and it ran fine! So although the carb floods a bit I don't think it was that cos I ran it with the tap off to see if it would clear and it made no difference. So , can the coil breakdown when hot and cause similar symptoms ? I've checked the resistance values and they match the spares I have but obviously it's cold now so not sure how to check, any clues good people, Dave Link to comment Share on other sites More sharing options...
blackhat250 Posted March 27, 2016 Share Posted March 27, 2016 Aye dave " its illimination process . swap the coil, then points/ condencer, how does it idle when warm ? Link to comment Share on other sites More sharing options...
Wessie34 Posted March 30, 2016 Author Share Posted March 30, 2016 Hi John, I hope you're well and managing to dodge the showers! Had it out again and still ran fine for 20 mins or so, then a puncture and no spare so will try again at the w/e. There's no points etc,some sort of electronic thing, checked with a tdc gauge so fairly accurate. all i did was shorten the HT lead 10mm and re-fitted the plug cap and so far so good. It does idle a bit high when warm but assume thats just a bit of throttle slide wear ? Thanks, Dave Link to comment Share on other sites More sharing options...
