June 17, 2026 at 1:24 pm #322297These valve things on the carburetor should they both move up and down when I rock the flywheel back and forth because only my right one is moving.However the one that is not moving is not stuck because I can move it with my finger.
June 17, 2026 at 1:33 pm #322300I have seen the oil left from running cause them to not move efficiently…If that makes sense…
Remove the mixer, disassemble the entire mixer, clean it and ensure all passageways are clear and clean. Reassemble and install.http://www.richardsoutboardtools.com

I’ve never noticed if one, or both, of the poppet valves lift when rocking the flywheel. When cleaning, compare the height of the 2 springs. If one is longer than the other, the poppet valve with the least resistance will be the one that lifts. Unless you find something I don’t think you have a problem. Try switching springs and see what happens.

Try squeezing the stretched one tightly between your thumb and index finger and sliding your fingers back and forth a little to see if you can get it back closer to the size of the shorter one. I don’t think it will affect running much. Might affect priming though. Don’t know. I don’t understand why one would think doing that would be a good idea but its not that uncommon . It was helpful to me to see someone start one so here is a link. This was the first time this one had been started in decades. https://youtu.be/hKX0mZji7aA?si=AfZUsBOi9xgBIfL-

June 23, 2026 at 3:01 pm #322790I am on the home stretch and about to try and start it!! But before I do I need to put the flywheel on any ideas on toque specs?

I believe the factory torque is stamped on the flywheel around the crankshaft hole. Look carefully and I think you’ll find it says “Keep Tight”. If you feel you need a torque value, search for a bolt nut torque chart. It will have a speck for that size and thread pitch. When you have had the flywheel off, after you have run it, you should check the nut to see that it’s still tight or still at the torque spec you used. This is the homemade tool I use.

June 23, 2026 at 7:22 pm #322815Do you have a estimate for ft lbs to get me close?

Not a clue. I’m 80 years old, self taught, that never had much need or experience using manuals. I tighten something till it feel right. Something like this I would check a few times. “Keep Tight” I suppose if I wanted to have a torque speck of that flywheel nut I might start at 35 lbs. If it felt good to me, I’d try it. If not, I’d up it a bit more. I’d run the motor a bit and check it. If the torque was still 35 lbs. I’d keep checking it each time after I ran it. If it stays a 35 lbs. I figure its tight enough but might add 5 lbs to be sure. If not I’d go up 10 more lbs. until it stayed tight.
