Ok I bought a doodlebug for my 2 boys for christmas this year and when they tried it a couple minutes after seeing it, they rode up the street and i thought it would go faster cause they had to push off to get it moving. I wouldnt budge with me on it, but i am 210, and my oldest is only 90 lbs. I started with the clutch grabbing on idle and searching on here I found what to do. But when I oil the clutch bearing do I need to remove the bolt or oil around the bolt and have it seep down, not in the clutch itself I know thats a no no. Also I thought this thing should go alittle faster and I noticed that throttle on the engine was hardly moving towards the rabbit on the label. Now I have searched on here and youtube to see what is the governor and is it the spring loaded screw under the throttle system or is it internal. I CANNOT stress enough I do not want to touch the governor, it is there for a good reason. I did however see on a thread here and on youtube the screw is NOT the governor and it can be adjusted or removed, I adjusted it back and now it pulls me up the road and back in a no time. But if that screw is the governor I will put it back where it was and let them ride it. On youtube there are videos that say it is not and other that say it is and to remove it, mind you 100% of the videos that say to remove it are made from 10-12 year old boys, I would have done the same at their age but I am 35 and had 3 spinal surgeries with 4 discs bolted together with more metal than a pontiac fiero has. So i do not to see my kids this way. If I upgrade to a 4hp motor is it simply remove the stock motor and install the new one, or would I have to do more like I would if I got the 6.5 motor on the new frame. Thanks and I help I didnt put anyone to sleep with this post.
