drove the Brat to work runs great no idle issues .. left it in covered parking deck for a week.. on start up she will not idle.. turned adjustment screw three full turns just to get home .....need help !!!!!!!!

Is this a California emission Brat? If so, there might be an issue with the fuel cut off solenoid, but by the sounds of it, there is some debris in the float bowl that is obstructing the idle circuit. The quick fix method for this is to remove the idle screw and blow compressed air in the passage, put the screw back in, lightly bottom it out and the back it out 2-2 1/2 turns and adjust from there after it warms up. If you don't have access to compressed air, pinch off the fuel line and run it til it dies. Add STP carb cleaner directly into the carb vent. Start it for just a few seconds then shut it off. Top off the carb with the STP and let it sit overnight. Unclamp the fuel line and run it. Should dissolve whatever is giving you grief. Great trick I use all the time for things that sit.

Thanks... skishop69 i will give it a try

Ok l ... tried Carb cleaner trick didn't work ... after using STP gas treatment two tanks fill of gas it seems to be getting better i will keep updating

For some reason, on my Brats (and three older GL wagons with the same carb setup), the throttle cable would tighten up and raise the idle since the butterfly was partially open. Check to make sure that there's some slack in the cable and the butterfly is closed completely when it should be idling. A simple fix if that's the problem.

Seafoam ..... i love this stuff 1 can tank full of gas and the BRAT is running like new
