At first my blasters RPMs would skyrocket when I started it. Checked for air leaks. None found. Cleaned carb. Now that revving doesn't happen every time but it does sometimes. It also has terrible throttle response. When I'm tapping the gas it seems to take a sec for it to rev, then has a bit of throttle hang. I also turned the tors not knowing anything about it anvil have to figure out where to set it. Any help with these issues is appreciated.
