Hi, Wullie and the usual suspects are:

2. Idle adjusting screw set too low.
3. Air fuel mixture adjustment too lean.
4. Pilot/slow fuel jet clogged.
5. Faulty accelerator pump.
6. Float level too low.
7. Float bowl contaminated old fuel, water, dirt, rust, etc.
8. Carburetor bowl vent line clogged/blocked/pinched.
9. Fuel line to carburetor kinked or pinched.
10. Fuel filter clogged.
11. Intake manifold leak.
12. The gas cap is not venting properly or fuel tank venting system blocked.

Have a 22hp husqvarna mower 54"deck motor has a miss when I go full throttle or half throttle in thick grass and blowers out black smoke like it is loading up on gas.What is my problem


Well, the simplest cause is a plugged air filter. Insufficient air with the usual amount of gas causes a rich, smoky mixture. Clean the air filter and make sure it isn't clogged with grass clippings.

The bike runs constant even when the throttle in not engaged, does the throttle need to be replaced?


The cable may need to be adjusted, or the carburetor needs to be adjusted.

Can i instal hidraulic clothing on my sportster 883 hugger


Making More Horsepower

  1. Full throttle only, on hot days, at low rpm. Carburetor is a bit lean in needle seat or main jet. Not too serious. We all have this problem sometimes.
  2. Full throttle only, on hot days, at mid or high rpm. Carburetor is a bit lean in needle seat or main jet. This is more serious. Get on this problem soon.
  3. Happens even while cruising at a constant speed. Carburetion is way too lean, or compression ratio is too high, or the gas you just bought is Tijuana special, cut with #2 diesel. Pull off the road, call for a trailer. This is big time serious.
Black smoke on full throttle acceleration.
Main jet is too rich.
Grey smoke on full throttle acceleration.
Bad valve guide seals, or bad rings. The engine was mis-assembled.
Grey smoke when you start the engine, particularly when cold.
Bad valve guide seals. The engine was mis-assembled.
Ticking sound which goes faster and slower as the engine does.
  1. Bad spark plug connection to ignition coil (pray this is it).
  2. Stuck lifter.
  3. Improper valve to valve clearance, or improper valve to piston clearance.
Engine misses at idle or full throttle acceleration.
Bad connection from ignition coils to spark plugs.
Truly crummy gas mileage, as in less than 40 when cruising, or less than 35 around town.
  1. Too much cam duration. You're blowing gas out your exhaust pipes.
  2. Carburetor is way too rich, especially in the midrange.
  3. Accelerator pump on carburetor is adjusted too aggressively.

How do i get more power from my 1975 cadillac eldorado engine ,also shes running too lean so need the mixture screws adjusting,are these in or out also the air filter is new thanks


The air/fuel mixture screws are usually capped off and the adjustment might not be possible, but if the air/fuel mixture screws are exposed then turning them in will lean out the fuel mixture, and turning the air/fuel mixture screws out will en-rich the fuel mixture.

With the engine fully warmed up and at normal idle speed adjust the air/fuel mixture screws one at a time, and turn each air/fuel mixture screw in until the engine just begins to mis-fire, then back out the air/fuel mixture screw one and a half turns to two turns to achieve a smooth idle.

Be certain that the air and fuel filter(s) are not plugged up (there might be a fuel filter inside of the fuel pump as well as the fuel filter/stone at the fuel inlet to the carburetor) and keep in mind that the minimum octane requirement for that engine is 91 octane, and 92 octane is the average octane rating for the premium higher grade fuel, so a bottle of octane booster added to a full tank of fuel will greatly improve the way the engine idles and performs.

That engine should have an electronic HEI (High Energy Ignition) distributor with the large distributor cap and with the ignition coil inside of the top of the distributor cap, and keep the tune-up parts in good condition and replace them when they wear out. The tune parts would consist of the distributor cap, ignition rotor, spark plugs, spark plug wires, and the spark plugs should be gapped at .045 in.

For better performance from your El Dorado a 1 inch spacer under the carburetor will really help a lot if the hood clearance will allow it, and you will need to set the ignition timing to 10 degrees before top dead center, and adjust the accelerator pump on the carburetor for maximun pump efficiency so that as soon as the throttle is opened there is two healthy squirts of fuel from the accelerator pump, and they should squirt as soon as the throttle is opened, and if the throttle can be opened and the accelerator pump does not squirt fuel at the same time as the throttle is opened, then there will be a lag or stumble from the engine on take-off and a severe loss of engine performance. (The accelerator pump must pump fuel into the carburetor at the exact same time as the throttle is opened)

For better performance check the adjustment of the secondary throttle linkage, and let me know if you require assistance with any of the proceedures.

Be sure that the vacuum lines to the EGR valve are correctly routed and that the EGR valve is not operating at idle.

Also, that engine has a plastic timing gear that was used for the camshft timing gear, and I would seriously suggest that it is changed before trying to get any performance from that engine.

Other than those modifications, the engine would need a better camshaft and the catalytic converter removed to increase the performance of that engine.

Here are some images to help assist you.

Ithe gas is pouring into the carbs and wont stay running unless pedal is to floor


You will need to adjust the carberator full flow systems if your not able to do this a mechanic can also do it but its cheaper to do it yourself

p.s. its only a screw you have to turn to do the adjustement

Toro lawnmower starts then cuts off. It appears to be leaking fu


If there is a fuel leak causing this problem it could be from the line going to the carburetor or the float bowl. If no leak is present there, could be flooding or a sticking needle in the carburetor allowing fuel to enter constantly.
