If this motorcycle is just coming out of storage or has been sitting dormant for a few months then I fully suspect that there is sediment in the carburetor high speed jet(s) caused by the evaporation of gas. The only way to fix this right the first time is to disassemble the carburetor clean it and make sure the jets are clear. It might look like the carb is clean but believe me after working on this stuff for almost 50 years now that foul gas and sediment gets into anywhere and plugs jets.

Not saying anything about your mechanical abilities but if you have to ask why this is happening I'd suggest you have it repaired by a motorcycle shop who is professional in these types of services. You can get yourself in a whole lot of hot water quickly if you aren't fully familiar with what you are doing.

Troy-Bilt Hand-Held Blower dies when warm and throttle wide open


You reported that most of the items I would've suggested, you have checked...
Good job.
A couple more things:
  • Replace fuel filter, it's in the gas tank
  • Check and clean the Spark Arrestor screen at muffler, when they plug up, it's a major restriction to exhaust gas flow
  • And check and adjust High/Low screws at carburetor, video attached.
  • And clean or install rebuild kit for carburetor
Good luck...

Hi,
You will need to have carbs cleaned out, especially if this gunk has got past the filter and into the fuel bowls of the carburetors.
\Sorry but it is the best next step to take to solve your engine performance issues.
Also have the tank cleaned out and the in-tank filter replaced as this problem will reoccur if the tank is not cleaned out also.
Hope this helps

I have a husky 455 rancher.never had a problem till today, worked fine this morning, now it iwll start but as soon as i put it under load it dies, cannot even rev the engine, it idles ok, but once i open...


When this has happened to me, it turned out to be a hole or crack in the fuel line. At the higher revs, more fuel is needed. The added "suction" for the higher demand pulls air into the line and the unit does not have enough fuel to run. Check for that first and also the fuel filter inside the tank. The filter might be clogged as well.

Keep us posted,

It dies when you give it gas.but it startes fine


When it starts it is running on the idle jet and when you open the throttle it is being starved of the correct gas/air mixture. Sounds like you have a blocked air filter or fuel restriction. Take off the air filter and try to start it opening the gas slowly. If that doesn't work, clean the fuel tank filter and try again.If that doesn't work, remove the carburettor and clean it with carb cleaner paying attention to any fuel or drilled holes in the body. Blow it off with compressed air and replace it. Ensure fuel tank has clean gas.

1994 chevy lumina van. It will start and idle but stalls when gas


Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
