    I have other question sir I appreciate ur help in regards to drilling out the dial pen area. I was wondering if you could explain that just a bit more or if by any chance you may have a picture ? Of how u did this in odder to fit everything properly also it’s ok to remove the electric starter and just have that hole open exposed as well ? Thank u sir.

    • @larryluna36
      @larryluna36  9 місяців тому +1

      Yes i removed the whole starter assembly and I now have the hole exposed. It will be safe to run as far as I know as long as nothing gets caught in there because the flywheel is exposed a little. I can actually show you exactly how I drilled out the area where the dial pen goes. I will have a video up soon but I’ll upload a UA-cam shorts about it since I’m trying out a new torque converter for it to see the difference and I can show you exactly what I did to make it fit.

    • @larryluna36
      @larryluna36  10 місяців тому +1

      Starting with a 420cc even stock is already a head start because of how much more power and torque it has over a 212cc. The carb I’m using is a flat slide 28mm and the jet is a 120 and needle position is 2nd to the bottom. It runs perfectly smooth it doesn’t bog at all but I think it could use a little more tuning because the spark plug isn’t colored the way it should be
