Thanks for that, I was told a while back on this forum that the 2103 had less bottom & more top end but when I went to purchase one, the online store said it provides more bottom end than the 2072, so I rang the shop & they weren't sure so I got another 2072.
My engine is modified with lightened crank & timing etc all done & is probably better in a truggy not buggy. I was after something that provides slightly less bottom & similar or more mid & top, I was also thinking about the Werks 2058.
