SOURCE: We have an rv with a onan emerld I set generator

Is your generator wired in to an automatic switchover in the motorhome, or do you have external plug in on face of generator, or near it. The power from the generator needs to be attached one way or another to the motorhome. It may be as simple as plugging the cord from motorhome into it, depending on what set-up you have.

I have an onan 4000 that will start for few seconds aThen shut down. Fuel pressure is high when I crack the line to the carburetor and crank it it will squirt fuel. Anyone have any idea?

Quite often it's just a matter of draining the old gas from your carburetor bowl and cleaning the bowl. It's also a good idea to clean the float hinge pin.

Your needle and seat is leaking inside the fuel bowl it can be adjusted but should shut off when bowl is full, it will need to be replaced, you say it happens when key is on, is the vehicle fitted with an electric fuel pump, this will cause leakage, as the needle will not seal with the pressure of the elec pump.

Onan Marquis good 5500. After 30 seconds starting, carburetor floods out. Cleaned out carburetor, still floods. Pinched off fuel line, ran till it was starved. Released, ran till it flooded again.

Hello Johnnie Thomas,

If GASOLINE is allowed to STAND it can VARNISH things together!

Either you have a stuck (or obstructed) valve seat...
(on the business end of your float)...

or the float ITSELF no longer floats
(freely: a malformed gasket can also obstruct free motion).

In principle the float bowl acts exactly like a "TOILET TANK"

When the fuel DROPs below the IDEAL level, the float (also drops) & the pressure released from the fill valve
(typically a needle &seat)...

Most carburetor kits include a new needle valve...
precisely because it is vital to the function.

Sort of a full CARB Rebuild... try cleaning the inside of the fuel bowl with Berryman B12.

Hope this helps.

Because we are at 8000 feet and brought our car from sealevel, can I manually adjust the carburator settings on my Mitsubishi Outlander 2005 2.0L 2WD

I thought that the 2005 Outlander petrol motors were 2.4 EFI motors. If you have a carburetor version, yes you can tune it for 8,000 ft above sea level. Being a 2005 model I would think that it should run well at 8,000 ft for they would be tuned very lean to start with to get past the smog laws. To change the settings you will have to pull the carburetor apart to change the jetting. The only adjustment that you can do on the exterior of the carburetor is the idle air mixture.

I have a Tecumseh OHV130 206810C. It sat idle for 2 years and was gummed up. Cleaned everything up but can only get it to run by spraying gas into the air intake. Could there be a fuel pump problem an

You follow the hose from the bottom of you fuel tank right to the fuel pump. If you don\'t have a pump, that same hose will go to your carburetor. Either way disconnect the hose from the carburetor. Put a can under hose and turn over engine. If gas flows your pump is OK. Next remove bowl off bottom of carburetor, ( with can under bowl), I believe you will find crap & water in the fuel bowl. I would drain all fuel from tank, hoses, and pump. Clean fuel bowl , you may need new bowl gasket, put in fresh fuel, try to start. Water in the fuel is a very common problem when you hear NO START. Caution when dealing with fuel, remember SAFETY, SAFETY, SAFETY, and did I forget to mention SAFETY. GOOD LUCK FRIEND.

I am lacking power and need to adjust my carburetor

the idle mixture screws are only for mixture adjustment at idle
at speed the idle circuit acts as a emulsifier tube to help with the fuel in the main jet
what you need is adjustable main jets or fixed jets for that altitude
talk with an accredited carby overhaul shop that knows about the carby you have fitted and the appropriate jets to use

Nikki carbureter have installed new kit but still floods up and runs rough any suggestions

remove the float bowl cover and set the wet float level. There should have been instructions with the rebuild kit on how to do this. If you don't have experience with carburetors, ask an old mechanic to help.

92 celica dies when it idles down, but will start back up

1st off your car doesn't have a carburetor, it is fuel injected and will compensate for any altitude change up to 5,000 feet, here is what u need to do.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
