18 HP V-TWIN GX610 V-Twin OHV Horizontal Shaft - Answered Questions & Fixed issues

Not sure what you asking..but by what you are saying the carb idle speed control needs adjusted..there should be two adjustment screws on the carb..one in the middle where it hooks to the motor it is the mixture screw do not adujust..the other is located where the throttle linkage hooks to the carb..adjust that one while the engine is running and out of gear..to the right adds speed the left backs it off...adjust to an idle speed that will allow you to operate the clutch..and put in gear..just make sure it isn't one of the safety switches that is not letting you put it in gear..good luck.

The return fuel line should connect to the gas tank.

Power wire grounding, repair or replace power wire.

if the fuse pops when turning to crank position the problem lies within the small solenoid wire to the starter (this wire goes from the ign.switch to the starter solenoid and is powered up when in the start position) this wire is shorted to ground....or the starter solenoid is shorted....best way to tell is unhook wire from solenoid and turn key to start...if the fuse does not pop its the solenoid....do this several times to verify

If there's no tag/tab with the #s on the engine, go to the unit it came off of and the tag for them would be under the seat with model and serial numbers. and year of mfg.

Goto smallenginewarehouse.com there u will get your specs

may have head gasket or centre manifold gasket leaking .. remove one spark plug at a x , check to see if it,s oily.. replace each one back so there,s no confusion after u checked all ..while ur doing each one, do a compression test to each cylinder to check if u have worn out piston rings .. gd luck ...

This is more than likely caused by the float sticking in the open position. I would remove the fuel supply hose form the carb, after gently pinching the hose shut with a pair of needle nose locking pliers (like Vise Grips). Next, drain the float bowl and retighten the screw. Then get another piece of hose the same diameter about 4-6" long and put it on the carb nipple. Next, get a can of carb & choke cleaner, (I use the O'Reilly brand but most brands will work) and slowly and gently press on the nozzle with the end of the straw barely inside the small piece of hose until it is full. Be careful not to back-spray into your face! Let it stand about 15 - 20 minutes then reattach the original hose and un-crimp it. Now try to start it and run it for about 1 minute or so then shut it down and watch to see if it stopped leaking. This usually works for me. Good luck.

The Cylinder closest to the flywheel is #1

NO THEY ARE DESIGNED FOR SPECIFIC VEHICLES

Probably done by design to stop a joyrider jumping in and driving off. Contact Avital direct. FWIW, remote starters are a whole lot of trouble. Let me know when you burn out your first starter motor because it does't release, or it locks you out and won't let you start.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 yearsmust try this bitman and reliable-store. Both are good

hello u will find a lot of wiring diagrams and circuit diagrams help books and stuff like this .. im a frequent buyer there since Im a mechanic so take help from there

Gravity feed tank need no fuel pump.....

If it is an electronic accelerator pedal you have, perhaps poor contact on the wires/connector on the pedal. Lay down on the floor, and check if the connector is in it's place and no loose cables. I had same problems with brake pedal and signals from that one.

Hi, If you did the usual testing (comp,Carb cleaning, etc.) then I would go to the electronic ignition box if it has one. I've been fooled before. Checking for spark, wire off, or plug out, isn't the same as a plug under compression , Good luck.

I am not an expert but if the compressor is working, there is adequate gas and no blockages I believe the high pressure side should be considerably higher - perhaps more than 250 psi depending on the gas type and ambient temperature. Perhaps the compressor is faulty or there is a blockage.

Is the engine set up with starter now? If it does then you will have to mount a momentary switch and hook 1 wire to a 12volt source and the other to the spade terminal on the solenoid for cranking. If the engine does not have a starter mounted originally then you may want to look for another engine.

Try changing a fuse.
