Hi all, I have an HS928 with the GX270 engine. I had just replaced the carb at the end of last winter due to a leaking problem with the old one. Now that I have taken it out of storage for this coming winter, I find that it has a hard time accelerating. If I go slow with the accelerator it seems to pick up rpm's just fine. But If I accelerate quickly it will bog down, choke and sometimes stall. Otherwise it seems to run just fine. I have tried adjusting and re-adjusting the 2 screws that are visible on the left side of the carb, but no luck. Any ideas??
