os max 46 sf engine ran on sat but not on thursday

I have an os max 46 sf engine in a trainer it ran great on saturday the 24 june 10 but i tried to run it again on 30 june 10 it would start but not come to full throttle without dying the only thing i did was go from wildcat fuel to coolpower fuel both at 15% mix. Will changing fuel cause that much of a problem any answers will be considered.

Check Glow Plug and Needle Valve Settings
by: rcdude07

Check your glow plug for heat. Remove it, hook your heat to it and ensure it glows red. If you have heat, then check your needle valve adjustment. It's not unusually during the summer that you may need to adjust it a click or two (on the needle valve) to compensate for the humidity and heat.
