To clean the carb on the Blast, here's the steps:
1. Remove carb.
2. Remove top slide
3. Remove fuel bowl
4. Spray everything down with carb cleaner spray (except rubber components)
5. Assemble in reverse order
DO NOT REMOVE THE JETS - just spray them out for now
Doing ANYTHING else almost always results in pieces reassembled incorrectly or not at all. This then leads to "Well the carb is cleaned so that's not the issue," when in fact the missing tiny needle jet is.
