Interviews by Linda Roxin

Rod, Larry & their crew spent a lot of time at the 2001 Tomahawk meet running their hydros.  They were converting from running on alcohol to gasoline.  They  were making carburetor adjustments & tuning their motors for races in the Badger State Outboard Association.

We want to thank the Terzinski's & crew for being so cordial & patient in answering our question, & for being so willing to share their knowledge & information.

Thanks guys!!!  Good luck in all your races!!
