i have a question about laser cut dv's. what i would like to know is is there a difference between 131 l/c dv's and lets say l/c 181 dv's? will the l/c 181's flow more fuel than the l/c 131's. i would like to know because im having my 131's l/c and im wondering if i should have sent my 181's. if anybody wants 181's ill have a set as soon as i get my l/c back. pm me if you want them. thanks richard.
