Hello Rob_fed,
I am following the diagram that you suggested on both your web site and this blog DIY Go karts. I am building a go kart for my kids out of PVC same as you have done. We are having a great time with it especially because they can participate due to the fact that there is no welding needed. I have two questions for you my friend. 1. According to the web page instructions, you have to cut the solenoid off of the starter engine.. I understand this, but what I do not understand is that the solenoid is where the connections for the battery went.. so how do I reconnect the power? As far as I can see there is only one connection to the motor. do I need only one connection? Do I weld/attach the positive end to the existing connection and then weld/attach the negative end to the housing somehow? What did you do? Question 2. While dissasembling the housing, I inadvertently removed the armature from the brushes. Since the brushes are spring loaded and stick out further than my armature is narrow, how do I get it back into the housing? The brushes are in the way. Is there a way to push them aside while I place the armature back in? (Update: I was able to push the brushings all the way back, they remained there until I placed the armature back in place, then I just had to knock on the housing to bring them back to the spring loaded position) I really want to get this working for my kids and would greatly appreciate any help that you can provide.
