Hi guys I've got myself a losi 5ive and had it about 4 months. It's had 20 tanks through it and have changed the piston ring and seals etc, I've double and triple checked the fitment of gaskets are correct and there are no air leaks anywhere , I've got the correct fuel mixture ratio, I've got the Zenoah 30.5cc O'Neillbrothers full mod engine complete with a walbro chokeless carb, high and low screws are set as per there instructions but have tweaked to no avail, idle screw makes little to no difference...? What else can there be...? Please help
