So, I've been researching for a while. Reading through backlogs and backlogs on this forum. Great information and such a wide range of personal experience. My mind has been in overdrive. I've got an idea for modifying the removable Venturi on an SCV equipped 1100. The biggest difference between the 1100 and 1101 is the Venturi size and throttle bore. Throttle gore for the 1100 I know is 1 7/16. Venturi size on the carb I have in front of me is between 1.1-1.125, right under 1 1/8". My idea involves removing the current Venturi and using a piece of PVC pipe, some time, and some sandpaper to fashion a Venturi with at least 1.25-1.5" inner diameter. I did a little digging and ChampionCarbs sells a replacement Venturi for the 1100 but it's $89. A bit pricy I believe. Of course I could see needing a jet change also after modifying the Venturi. So far my next step is to remove, without damaging, the existing Venturi to better understand if I might be able to modify it, if the walls are thick enough or replace it with something else. This is an idea I have as a step around not being able to upgrade distributors for less than $400.00 as my 170 engine has the 1/4" oil drive and a DSii conversion isn't possible for less expense. What is everyone else's thoughts on this. I even thought if possible I could find someone to turn me a Venturi on a lathe out of aluminum. Wondering if anyone sees any flaws in what I'm thinking, what might or might not work, and possible solutions???
