Thx for suggestions.
Also the cheap A$$ chinese clamp was broken on the carb to engine side, so the A/F mixture was too lean, my boy complained 2-3 weeks back about lack of power.
I had a hose clamp lying around and put it on, heck he notice instant zip in acceleration again,
POS chinese junk, I never touched this, it musta broke thru that over time via being overtourqued at their factory???
In USA factory workers have torque limiters ......
