After getting the internal parts correct in this 88-89 model stock carb 43B10 an taking it apart an cleaning & adjusting everything inside it myself. I put it back on set air screw to 1 1/2 turns out. With key lol or run switch in off position I prime kicked it about ten times . Then with run switch on this beast fired up 2nd kick after sitting for 8 years. I let it idle for a few min idled perfect then I held the throttle wide open for about 5-10 maybe 15 sec and this beast came back to life omg it revved and sounded so much better than before when most of the internal part s were incorrect. I also did the same thing to the stock 87 carb 43B00 everything in it is clean an adjusted properly. Didn't try it cause sum1 here said there was a leaning out issue at high speed or around corners with it. Plus also noticed the 43B10 carb had sum different features an floats than stock 87 43B00 carb.
