SOURCE: engine cutting out after 10 minutes

Try removing, then putting on the gas cap. The diblasi gas cap is loaded as a one way valve to prevent spillage and vapor leak. it might be clogged or malfunctioning and would need replacement if the diblasi starts after after cycling the gas cap.

I would not recommend taking it apart. There are ~10 parts that will come flying out. You can try a fuel soak to see if it helps. Otherwise, you gotta order from diblasi in italy (like I need to get around to doing).

SOURCE: moped engine will start, but will die when given gas

It sounds like you have answered your own question automatic chokes are designed to keep the motor runnning at Idle until the machine is warmed up while I dont think they are a good thing on motor cycles particularly in warmer climates. the one question I must ask how many k's has this little beast travelled if its alot being two stroke it is probably due for a decoke & a new set of rings if not A rebore new piston &rings all the best

SOURCE: motorcycle starts and will run for 3to 5 minutes

Ok, you've either got a lose of spark problem or a fuel problem. To solve your problem, you've got to figure out which one you've got. The next time it does this, take a spare set of spark plugs and put them in the plug wires. Ground them good to the engine and press the start button while watching them. Do you have a good spark. If so, now you've narrowed your problem to a fuel issue. If not, you've got an electrical problem.

Fuel problems are the simpliest. First, loosen but don't remove your gas cap and ride the bike. If this fixes the problem, replace the fuel cap as the vent valve in the cap has went bad. Check for full fuel fuel flow through the petcock. Your bike may have one of the vacuum operated petcocks. These are notorious for giving problems. I'd suggest replacing it with a high quality manually operated petcock if it proves to be your problem. To test it, remove the fuel hose and the smaller vacuum hose on the rear of the petcock. Using a hand operated vacuum pump. apply vacuum to the nipple on the backside of the petcock. You should have a full flow of fuel through the petcock. If not, replace the thing.

If you don't have a spark when you check the plugs, start carrying a can of "component cooler" with you. The next time it does this, spray the ignition module and see if that brings the bike back to life immediately. Try spraying the pickup module in the timer cavity. You may have to drill the rivets out of the cover to get to this component. Do not replace the rivets with standard rivets,,They're special rivets, get them a the Harley shop. When you spray something with the component cooler and your bike come back to life immediately. You've found a temp problem. Replace that component.

Good Luck

I have a 1989 Ford f150 drive for about 30 minutes it dies out or stop and want crank for about an hour

I would unplug the gas cap when it stalls; if you hear a hissing sound, change the gas cap, because it builds up a vacuum in the tank.

Husqvarna riding lawn mower yth 2448 cuts off as if running out of gas after 10 - 30 minutes

Mine would run for about 15 minutes and die. I pulled the carb off and thoroughly cleaned it. Inside the float bowl there is a plastic device held on by two phillips headed screws. Under this device are two tiny tubes with small holes in the side of them. Make sure these are clean. I used carb cleaner in a spray can and a tip cleaner. Make sure to wear eye protection if you use spray cleaner. I reinstalled the carb and, so far, it is working fine.

The car will start and run for about 5 to 10 minutes and then die. If it sets about 15 minutes it will start again. But that is it.

Have the coil tested at your local auto parts store. When they warm up sometimes this will occur. good luck. Jerrod

6yr old Craftsman Lawn Tractor - Koehler 18 HP Auto. Sputter&Dies

Try running it again and when it starts to die remove the gas cap and see if it starts to run better. It's possible that the gas tank isn't venting correctly. If that doesn't work post back and we'll try to come up with some other solutions.
