Just as slow as before my mods..
You can see the long slots in the bracket I circled in red. You need to look which screws hold the throttle cable bracket to the main bracket, loosen them and slide the cable bracket further back on the main bracket until the carburetor opens all the way when the pedal is depressed. Once you do that, check and make sure the throttle is all the way closed and is not being held open by the cable after making your adjustment. In other words, LEAVE your block of wood in place and make the adjustment. Make sense?
