Thank you all for posting. Alleyoop, you were right on. I had to go out of town for work but when I got back I pulled the petcock and pushed air through it until it cleared out whatever was blocking the reserve setting.
It's amazing to me that a 35 year old engine that had been sitting for at least 10 years only needed a little de-rusting, a carb clean and cleaning out that valve and now it runs great.
Thanks for your help. It's because of forums like this that I can get away with trying to tackle these projects.

I have a barn find 1977 Honda Express. I thought it would be a fun project my girlfriend's younger old son and I to clean up. It had been sitting for over 10 years but it was free so I figured it was worth a shot. Remarkably we've been able to get it running without too much trouble and we have been slowly working our way through the little issues like cleaning the carb, de-rusting the gas tank, new brake pads and the like. One of the problems I can't figure out is the reserve tank. The fuel valve has 3 positions. On, Off and Reserve. Fuel runs through fine when turned to On, but nothing from Reserve. You can see what the valve looks like in the attached picture. I removed it from the petcock and blew air through it. As you might guess the Air went through fine when switched to On, but couldn't get anything through when switched to reserve. The plastic tube you see in the picture is needed to run up through the petcock and into the fuel filter that sits in the opening of the fuel tank. However this tube is about half the size of the petcock. My guess is that when switched to On the fuel is sucked through this tube. Then when it is switched to reserve it should be able to somehow draw fuel from around the tube. On my fuel valve at the base of the tube there is an o ring to make a good seal and some sort of grout like substance. It looks like fuel could be drawn through here if the grout stuff wasn't there. But the grout substance could also be there to hold the tube in place. Is it possible that this grout like substance is simply built up corrosion (it does scrape away fairly easily) or am I missing something else here. The problem is that the fuel tank is so small this is really limiting how far the scooter can run. We have to fill up fairly often to keep it happy, especially when hills are involved. I can buy a new one off of ebay, but I'd like to do some research my options before shelling out the money. Anyone have any thoughts or experience with this sort of thing? Any help would be appreciated. Thanks. Attachments:
