[NSRCA-discussion] YS-160 setting

[Matthew Frederick]

Jason,

Does the carburetor have a venturi restrictor installed? YS sells a part 
that restricts airflow and reduces fuel consumption for the 140 and 160 DZ's 
by reducing the size of the air intake on the carb. It conserves fuel with a 
tradeoff of a loss of about 300 RPM on the top end from what I understand. 
I'm running the 140 with the restrictor, and I can't imagine needing more 
power for my Genesis. Hope this helps.

Matt
