Question about Craftsman 42 in. Deck 19.5hp Lawn Tractor

1 Answer

Crafsman 19.5 opposed cylinders full throttle only

Starts fine, runs ok but only runs at full throttle. Linkage appears to be working ok. Will a sticking float cause this? Or a hole in float? Anyone else ever have this problem? Butterfly valve in carb appears to work ok.

    Sounds like a linkage problem on your opposed twin. Is you throttle cable working properly? I would check to see if your throttle is actually moving the linkage going to the carb. Neither a sticking float or hole in float would cause this problem. The fuel filter has nothing to do with this.

    What engine? Kohler Command or B&S V-Twin? Also, when was the fuel filter replaced? It is possible that your engine is generating enough vacuum to get past a fuel filter obstruction at full throttle, but is being choked off at low / part throttle.

1994 Chevy Camaro, 6 Cylinder, stalling problem

Try cleaning the throttle body and the idle speed control valve, they get full of sludge and this causes stalling. Use a product called CRC Throttle valve cleaner on both parts, DO NOT USE CARB CLEANER IT WILL RUIN THE PARTS.

How can I get full throttle out of 1978 115 hp evinrude

That is a wide open question. Has it ever run full throttle or is this a new install? Check linkage for full travel. If OK, could be wrong prop, clogged carb, blown cylinder. 1977 was a bad year for OMC pistons. some 78's could have the same problem.Lots more info needed.

I can't get my Chevy sm 400 to rev past 2,400 rpm.

you didn't say if it starts and runs fine and idles fine. Check the throttle cable/linkage to make sure it has full free travel. Check the firing order and make sure all wires go to correct cylinder. Make sure you have good gas, no water in it etc. Contact the rebuilder for ideas, before you do damage.

No power

Did you check the throttle cable linkage to the carburetor? There is a retainer for the throttle cable near the carburetor. This will sometimes come loose and even though you move the throttle lever forward it may not be moving the throttle cable at the carburetor.

Have 115 Hp mercury outboard motor missing at full throttle and on idle. At mid throttle it is running fine. Any Idea what the problem could be. Thanks, Milton

Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )

Anthony, this could be from the governer linkage which is intended for maintaining a specified top rotation per minute speed ( R.P.M ) is a possability im not sure of your specific adjustment procedure allthough most are a simple lossening of the linkage mounting to the shaft bolt while this bolt is loose you push the linkage to full throttle travel activation allowing the control linkage that was lossened to turn in its mount ( pivot) and keeping the threw the block mounting at full activation range ( travel ) in its farthest position re tighten the arms securing bolt,to secure it at its proper activation range ( at the pivoting point) I hope this helps if your unfamiliar with this type of governer control linkage, i would seek to locate a diagram on line that you can view to assist in your specific engine's linkage adjustment , and another possability is your carbuerator's High speed needle valve is to lean or to rich hope you analysis the problem Steve

Only runs on full throttle

Are you saying full throttle, or full choke? if full throttle, you should be able to set the idle up. the idle screw will be the one when you give it gas, it will be the screw on you'r throttle linkage. If full choke, maybe the spark arrestor is plugged. You can remove it by removing the muffler.It would be between the muffler and cylinder head. You don't need this to run.I hope any thing I posted will help.

Sputters & quits at proper RPM for engaging trans or mowing deck

If the choke has an adjustment point, then adjust the choke to a good overall working powerband. If it still doesn't act correctly, look for vacuum leaks. If it is an option, you may want to install a manually operated choke lever.
