Replaced cables with oem and also aftermarket plastic main cam and idler on inside. All looks well and is adjusted but still have the 3inches or so of travel before ingaging the carbs after putting in gear. Same slack, maybe not as much when putting in reverse. Is that normal or is there some other part that was missing before I rebuilt the box? Have scoured the dia. pic and can see nothing I missed. From wot fwd to wot rev is almost a full 180 degrees. Any suggestions?
