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.

Briggs and Stratton propane gernerator will not run.


The engine is starved for fuel. Check fuel flow. Possibly a dirty fuel filter someplace in the line or the regulator has low flow.

You can verify this by putting an UNLIGHTED Bernz propane torch into the intake. If that improves it, then low fuel flow is the culprit.

Fuel filters for propane are very fine and can plug up easily. I am not sure where yours are, however I would check at the inout of the regulator for one there for sure.

ONAN GENERATOR STARTS THEN ONLY RUNS WITH CHOKE ON


Hi,
This sounds like a problem with fuel settings or dirt in the jet.
If you can find the carb adjustment screws, with it runing on full choke - screw it in fully untill it stalls, then back out to original position, then restart.
Take off choke and adjust setting untill it runs well when warm with choke fully out.
You can then try and make it run leaner without stalling.

I have a Honda EU 2000i generator. With eco switch on or off the generator revs up every few seconds. If I turn the choke to half it seems to almost get rid of the problem. What can be causing this?


starving for fuel. the generator will always rev up when it is under a load or about to run out of gas. there will be a few adjustment screws on the carb... one for air and one for fuel. try increasing the fuel a quarter turn and see how that does

Engine starts and runs fine for about a minute


try to clean out the carb first with auto parts carb cleaner, then you may need to buy a totally new carb for the unit, as this company will NOT sell parts for these carbs due to the carb setting is sealed & has to stay at a set level for voltage output and setting

J.D snowmobile 340 73 carb wont idle appears internally clean.


I would have your compression tested, if its a two stroke, and you can use tools with out breaking things or yourself, pour a cup of fuel down the left hand side of the carb and take the right hand side of the carb off and crank it like mad, if fuel leaks from there you better get to a repairer.

other wise the idle adjuster is usually on the left hand side where the accelerator linkages are, it will be a screw where the linkage touches when the throttle is closed. not too hard to find if you have a light source.



Hope this helps.


If you want any more help just ask :)

5500 gas generator


Recently purchased UST 5500 from Pep Boys. Had same problem during engine break in period. Found that the carb will not draw gas when generator is on level surface. Mine has the wheel kit and it causes the fuel inlet to be at highest point in tank. If you block up the wheels and change the angle of the tank it will improve fuel line pickup. Also check gap on plug, mine was way off from factory. Also check the routing of the spark plug wire and make sure it is not getting forced off the plug by tension from breather hose. Once the engine starts make sure to push choke back in, it will run for a good while choked but it will eventually shut off if you don't push choke back in. Hope this helps. Took me awhile to discover the fuel feed issue.
