Thanks for all the helpful comments. Well, I went ahead and with my grandson put it all back together, and he carried it out to the cart. We got it all connected, and he stepped on the pedal. It started right up and ran without the big smoke clouds. Yay! We idled it a little at medium speed, and then he went for short rides, still not at full speed yet. A little blue smoke, but I think that may go away once the rings are seated, etc. Happy day. Happy grandson. Happy grandpa. Thanks again.
