donny o Posted February 25, 2009 Share Posted February 25, 2009 Getting my 74 dt 125 together and starts very easily and idles like a champ but now that the snow has melted off around here I took it up the driveway out of my shop and she starts off ok--in first gear but as I get going and giving it more gas it bogs big time--actually totally cuts out until I let up the throttle. Is this just carbeuration or is there something else text-book here I should know about bogging out under a load? Appreciate any help. Thanks!

Moderator Airhead Posted February 25, 2009 Moderator Share Posted February 25, 2009 Hi donny o, It would be worth checking the spark plug gap at this point, it happens to be harder for the spark to jump the gap when the engine is under load (ie wide throttle), you say the engine seems to die completely with wide throttle opening so wel worth a check here.
