I just got my first M715 at the beginning of the summer, fooled around with it enough to get it on the road but lots more work to do and questions to ask so Ill start with this.
I’ve got a vacuum line (I think thats what they are) coming off the front pumpkin and another line come off the axel on the drivers side of the rear pumpkin, they merge and the line dead ends in near the carb. I’m guessing it used to be hooked in to the vacuum system some how but don’t how. The carb and all lines have been replaced and I can’t find any info about it in the repair manual. Maybe there not stock? And is that why I cant get power to both front tires in 4 wheel drive? Any info would help thanks.
