SOURCE: Coleman Powermate 6250 only runs with choke closed/air restricted

A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems

Hello:

>>The Following is the Instruction File for Setting the Air Mixture Screws. Any Input is Appreciated. The Procedure is the Same for 1 or 2 Mixture Screws, Just Use the Instruction File and Skip Over the Section with the Missing Mixture Screw ( Usually the H Mixture Screw).
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air (L) and Main Air (H) Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Set the Throttle Full Open, Start the Engine.
>>Turn the Main Air (H) Mixture Screw Clockwise Until Proper Revs are Obtained. **Carefully Use your Finger and Move the Governor Arm to Rev the Engine (on Chainsaws and Trimmers Use the Trigger to Rev the Engine) Until you Reach Max RPMs (on Chainsaws and Trimmers, the RPMs are Not Set to MAX. Set to Max and then Reverse the Setting Screw 1/4 or 1/2 Turn. If the H Mixture Screw is Set too High; the Engine will be Starved for the Oil in the Gas and Damage the Piston and Jug/Cylinder) and the Engine is Running Proper at Full Throttle Up a Grade. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs.**
>>Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air (L) Mixture Screw so there is No Hesitation when Rapidly Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
>>If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy.
>>Thanks.

Respectfully

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

my guess is that its not the carb at all but it might be the gas line in side the tank is cloged to the point whare you need to have it on choke in order to pull enough gas to the carb which would be the reason for it not wanting to come back down to idle quickly or it could be the fuel pump is cloged and if you tried that already than the fuel adjustment is way off and will need to be adjusted while a friend or family is keepin it running






and if that is not the problem than email me.
good luck:)

SOURCE: Too much fuel pumped into the carb. What to do?...adjust?...set?

The idle air control valve may be at fault, also the throttle position sensor may be telling the engine th wrong information and sending too much fuel, a couple other ideas come to mind but I not an expert. A faulty injector is one of them.....I another idea that may help as well: Vacuum Leak: The ECM will try to compensate for leaks up to a certain size. This will cause the ECM to compensate and possible send too much fuel to the engine...???? Good Luck

Brand new snow blower


A brand new snow blower ?? Who made it, single or two stage, 2 cycle or 4 cycle, Tecumseh or Briggs or China engine ??

Without knowing it's pretty hard to tell you if it's adjustable. Have you tried reading the manual ?? Did you try asking a dealer ??

Most newer machines do not have any adjustability as to fuel mixture. It's strictly an emissions issue. Many are so lean they won't run properly without being full warmed up before taking the choke off and some will still need a little choke to keep from surging. If you look on youtube you can see many cases of it. If you bought it new you can take it back and have them replace the carb and hope it's better. If you have some skills and are willing to buy miniature drill bits (I did) you can take the carb apart and gently drill out the brass main jet to get some more fuel in there. This is also a procedure you can find on youtube.

Mantis will only run when the choke is on. If I try to push the choke in it dies.


Having owned a Mantis for many years it sounds like your air/fuel mixture may be to lean when you push the choke in. First check the simple stuff. Make sure you are using fresh fuel with the proper 2-cycle oil mixture. Check or replace the fuel and air filters. Replace the spark plug annually. These are the routine maintenance procedures found in your owner's manual. If none of this solves your problem either the carb fuel mix adjustment screws are not set properly or a carb rebuild kit is needed. The proper setting for the mixture screws should be detailed in your manual. Removing the carb and replacing the needle valves, gasket and other items takes a little more expertise. Before jumping in to this and assuming all other maintenance has been performed press the fuel primer bulb several times before trying to start it. You should feel resistance after 3-4 pushes. If you don't feel any resistnace the carb is not being primed and the bulb needs replacement (you may notice a small fuel leak if this is the case). If you can get it primed, pull the choke out, start and let it run a minute or so. Then make small, gradual changes by turning the fuel mix screws (not the idle adjustment) as noted in your manual. Try to push the choke in half way or as far as you can without killing the engine. If may run a little rough but continue tweaking the screws until it smooths out a little. Gradually continue pushing the choke in and turning the adjustment screws as needed to keep it from stalling. This is best done with the tines supported off the ground during adjustments. Just make sure to protect yourself and others from coming in to contact with them. When set correctly you should be able to achieve full throttle with the choke fully closed. A little time and patience should get you up and going again. Of course you can always contanct Mantis at www.mantis.com or call them for troubleshooting assistance. Hope this helps.

Hi i,ve got a cb900fz running very rich on cyls 2,3,4 the carbs appear to be standard i,ve recently fitted new air cut off valves float heights appear right but are plastic one piece units so non...


sound like the carbs need to be synced if throttle plates are fully closed at start it would cause a rich condition and no need for a choke becase there is very little air passing through mostly fuel if they are not eqaul there would be hesitation when opening throttles til about 1/4 throttle

I have a poulan wild thing 18in it will start and run for about a min then shut off i change the carb. coil and plug when it dose run i have to have the choke on all the way


If you have to choke it for it to run it is to lean. Figure out why, lean operation will cause P&C failure.
It sounds like there is a fuel delivery problem. Check the fuel filter on the free end of a hose in fuel tank (manufacturer recommends an annual replacement). Check all fuel delivery lines especially at fittings and bends for cracks and holes.
If all hoses and carburetor boot and is good and the carburetor isn't loose adjust the carburetor, start at 1.5 CCW from lightly seated. All adjustments are to be made using a fresh (3 months or less) fuel mix at a 50:1 ratio, at the elevation where it will be used, and a clean air filter. HTH

Carb is acting weird cant seem to adjust


That is the choke adjustment,have you checked your timing on the motor and check and see if the vacum pod on the distributer is working. also check your vacum lines for any tears or cracks in them.
