Take a look at the "Online Resources" portion of the forum. I uploaded a bunch of stuff on tuning, troubleshooting ,fuel system and more , for the 108s.
I would first start out making sure the tuneup stuff is done - plugs, wires, filters, etc. After that, I'd look at fuel, air and spark. Air is rarely messed up, so look to the fuel management system, and whether you have a strong spark.
