GrandPa kid Posted February 13, 2011 Report Share Posted February 13, 2011 ok so im new to ratsun, i have known about this website for a few years now but i just registered a few mins ago. now i drive a 1978 datsun 510. it has an l20b engine. for some reason the engine boggs out when i slightly step on the throttle. ive had the carburetor rebuilt twice and that didnt change anything. a few people have told me that the jets have to be replaced how ever that couldnt be the problem since the carb was rebuilt twice, or theres a leak in a vacuum line. i dont know what may be the problem and i was wondering if anyone here can give me a hand. thank you for your time. if you guys wanna see it i can post a few pics.
