paquirl Posted February 2, 2015 Share Posted February 2, 2015 1980 BRAT - FACTORY ORIGINAL, RUNS GREAT, NO MECHANICAL PROBLEMS Carb recently rebuilt and the little pump thing replaced as well. Tuned up and oil changed. New fuel filter. Fresh quality fuel. New battery. PROBLEM -> Dies at idle when you take your foot off the gas. If i'm going at faster speeds and drop it into neutral to coast to a stop, it will die before it gets there. OIL -> Can anyone tell me the recommended oil for this vehicle?

DaveT Posted February 2, 2015 Share Posted February 2, 2015 It should be 10w 40 engine oil, unless you are in extreme cold. Link to comment Share on other sites More sharing options...

Thank you, Andrew A good place to start on your idle issue is a simple check of the idle speed and mixture adjustments. Are you saying it simply wont idle at all or it dies after you use the throttle instead of idling? I cant say ive ever looked in an owners manual from 1980 but i can say the 82-84's ive owned called for straight 40 over 90*f. And 20w-50 or straight 30 from 90 down to 30* or something like that. Living in the south west ive pretty much always run 20w-50, tried 40 and 10w-40 and never noticed any difference at all on the gauge or in cold starts.
