I'm not really sure if this is the right place or not, but I've tried to get help on a different forum, and it just isn't as active as this one. So I'm asking yall for some help.

I just restored a 1970 Honda QA50 that had been lying around in my garage for about 20 years. I replaced the rings because it had no compression. It was running excellent, and was even starting using the kick starter. Then all of the sudden it just stopped running. It lost all of it's compression again. I tore the engine back down and checked everything, cause we thought it might be a valve. Everything seemed fine so we adjusted the valves. When it was all back together the compression was back, but it was blowing compression out the intake. It would try to start running, but would not keep going. Can anyone give me some help?

Here's a video of it running.
