Remove and clean the carburetor. The high speed jet is most likely colgged and is causing the condition. I assume the fuel filter (if equiped) has been replaced. I'm also not sure of the age of this mower, but this would be a place to start. Spark plug has been replaced? Just a thought.

1993 HONDA SHADOW VLX 600, STARTS RUNS FOR 5 MINUTES AND DIES, I CHECKED EVERYTHING FUEL RELATED,IT'S NOT A FUEL PROBLEM


From your description you can be fairly certain it is an electronic problem.

I had a similar problem once with my Honda CX500. I found the connections to the ignition module had gone green and a good clean up restored normal running.

Powermate generator 3250 runs for hours then chokes out runs rough


If it runs for hours under the same a mount of load then, chokes down, make sure fuel lines are fully clear, it may operate with a full tank of gas then when the weight of the fuel in the tank gets less has a problem. When it chokes out fill the gas back up and see if it works again. Also make sure the choke butterfly is not closing again whilst hot. I don't know how many hours are on it, but a decarb may be in order, especially if it runs for hours no issues

I have a 24" snowblower that surges after 1 minute of running, after 3-4 minutes stops and will not restart until several hours later, does the same thing over and over


This sounds like a choke issue. Do you have a choke on that engine?

The purpose of a choke is to allow for a varying air:fuel ratio depending on how hot the engine is. A cool engine needs a more rich mixture of fuel to air. Once the engine warms up, it runs best with more air. The Choke is a mechanism that allows the operator to manually adjust this mixture. Generally, the choke is closed to start a cold engine, then is opened in 2 or 3 stages as the engine warms up. As the operator, as the engine starts to run smoothly, you would actuate the choke to the next notch, changing the fuel:air ratio so more air is mixed in with the fuel. It's probably best to give the engine a few minutes to warm up while you progress through the choke stages until it's fully open providing the best mixture for operation prior to beginning to clear the snow.

If you follow that process and the engine stalls when the choke is opened, then you need to clean your carburetor.

Honda pressure washer 5hp will only run with the choke on. Was running fine for about 1 hour


The problems you describe are usually indicative of a blockage in the fuel system somewhere in the carburator or a damaged gasket that's letting in too much air. With the choke on, the vacuum in the carb goes way up and forces more gas through. Remove the carb and check the gaskets and insulator if it has one. Then check the float bowl for debris and blow out all the passages in the carb.

Motor will start on choke setting and then it immediately dies when moving the choke lever to the run position. Cleaned carb, new plug new air cleaner and checked all linkages. the motor has new oil and...


You say you cleaned the carb. If you did that by spraying cleaner in through the choke, that's good, but it doesn't get to the root of the problem. The problem is getting the gas into the carb. Try this. drain the gas. Put a small amount of carb cleaner and gas in the tank (about 1:1) Start it up, but don't run it dry. Let it sit for an hour. Then start it up and run the tank dry. Then try just a little gas to see if that fixed it. If not, repeat. Good luck Al K

My suzuki 125 wont start I recharge the batterry and replaced the sparkplug and start during it's on choke but if I return to normal it dies. pls help me


It's a carburated bike. You need to have your carburator cleaned. It's not a difficult job, howver if you are not comfortable with what your doing a shop will charge a half hour or 1 hour o clean it for you on average.

Your carborator mixes your fuel and air. when the bike is at idle it is only getting fuel from the "idle" needle. The smallest needle in the carb. These needles are hollow. As fuel sits in the carburator for a long period of time (over 2 weeks) then the fuel can gum up and clog the neeedle. If it runs when the choke is on but dies when you take it off the choke this is what is happening:

On some bikes a "choke" doesn't actually choke it of fuel, sometimes it actually enrichens it. Your bike is probably set up to open another passage way besides the "idle" needle allowing fuel to go into the engine from another passage. you shut the "choke" off and now it only has the idle needle to get fuel from. If that's clogged the bike dies.

A can of carb clean and a screw driver is usually all you need to clean a carb. But if done wrong you will pay more to have a pro fix it.

Will not start when cold if you ues starting fluid and get it running it will stay running until its shut off but if it sits and cools down for approx 1 hr it wont start the fuel valve was just replaced...


Sounds like the choke is not closing. Perhaps it has become detached from the manual throttle.
A simple test you can perform is to let it cool for an hour or more, remove the air filter and cover the air intake with your hand (making your hand a manual choke). If it starts right up, then the real choke is the problem.
There are two valves that you can see from the top of the carb. The one closest to the air cleaner is the choke. The other one is the throttle. Both valves operate through 90 degrees of rotation. The choke should close all of the way with the lever in the start position and be open all of the way with the lever in any other position.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.
