cen colossus 7.7 engine problem

Postby whip5426 on Fri May 15, 2015 10:46 pm

I have a 3 month old cen colossus it runs fine until I shut it off to refuel or it turns over and then shuts down on its own. When I go to restart it immediatly it will not restart until I let it cool down it has done this since the first day I had it what's wrong is it jetting

Sounds like its overheated. The engine setting must be off. Please donwload the instruction here and adjust the needles accordingly. http://www.cenracing.com/support/downlo ... G70365.doc

Also, you MUST use 30% fuel. 20% fuel will NOT cut it. http://www.cenracing.com/support/downlo ... G70365.doc
