    Well I did not put new ones on yet, but manipulated the current ones to close the best I could get them to test out. It worked, throttle valve can close and motor can keep a good idle.

    Being curious and wanting to check the reed valves. I took them out and this is what I found. I am sure this is the idle issue. As it seems like it's getting too much fuel when throttle closes to idle. Check out the pic and give me your thoughts. You can see light on those two holes and there is...

    Yeah I had it set pretty good in that 2nd video. I had the idle adjustment set to the lowest I could go with out it dying. But had to have the throttle valve open a smidge to keep it going. I am gonna check vacuum leaks and carb swap and test. Got parts on order to address the baffle gasket...

    @Crosbyman I Will be trying that for sure when back together, I don't have the lean sneeze tho, or maybe a form of that? What's happening to this motor is when I back the throttle down to its Lowest, the engine just dies. No sneeze, just dies. Ican make it sneeze by adjusting the low speed...

    Would the baffle gasket leaking cause that idle issue? Or the missing drive shaft oring? Or the damaged waterpump grommet?

    195928 pic was facing the bearing. 155508 was facing the spring and that is fuel mix on that side of the seal. I will post pic of bearing as soon as I get home. Thanks again for you time and reply.

    Well that was easy. Clip spring and pulled the lower seal. Will update when she's all back together. Hoping for a good idle. There was some fuel on the top of the seal, so it could have been leaking. Rubber inside looked old and worn too.

    @F_R any ideas what could cause the dying when throttle valve closed? After taking this thing apart I know several things needed to be fixed, driveshaft o-ring, baffle gasket, water pump grommet, and I will replace the lower seal just for knowing it's done. Probably replace impeller since I am...

    I will inspect it later today. Got new baffle gasket and carbon seal on the way. Gotta find a cover seal though, they are scarce.

    So what needs to be done to get that lower crankshaft carbon seal out? What bolt do I loosen, the two on the side then what others, I think I read something about 3 bolts need to be loosened and then the seal will come out...

    Well I took it apart today. Found that the drive shaft o ring was gone, water pump grommet was all messed up and broken, baffle gasket was gone, and the housing cover seal was gone. Assuming that was all bad, I am sure the carbon lower crankshaft seal is bad too. Before I order all the things I...

    Yeah I was suspecting that too. Compression is 130/135. Plenty of compression. When I put the hood on it runs a little better. I am showing it tomorrow. I have it up for sale soo we will see what goes down. I had it to the best it was gonna be that last video I put up. Then I pulled the...
