I have 10 weeks to complete a project on a Honda 5.5HP 4-stroke engine. The engine is for a kart. It is normally aspirated and has a sponge carb. I must do the following: (1) Examine the design/construction of the engine (2) Propose a new/modified design (3) Build (4) Test (5) Report This is the engine: http://cgi.ebay.ie/GO-KART-KARTING-...yZ122308QQssPageNameZWDVWQQrdZ1QQcmdZViewItem I have a lot of ideas about what could be modified, but I'd like to hear other people's opinions. What do you think would yield the best performance increase? 10 weeks is a very tight timeframe so that also has to be considered.
