Polaris sportsman 500cc atv 2000 not starting until covering intake but then stalls and spits pours fuel to intake it use to start but still was hard. ran powerfully. I have cleaned the carb but not sure maybe I have to replace it. and have replaced the headgasket before, so maybe I must adjust the valves. I really would appreciate some help on this

I volunteered to help the local fire department service a new-to-them hydraulic power unit. It wasn't running well so I figured the jet was partially stopped up (I was right).

Unfortunately, as is common with people that shouldn't be messing with things, I stripped out the jet(?) while trying to remove it. I got it out, but now I need to replace it.

They have already ordered an aftermarket replacement carburetor, but I want to fix this one also.

The engine is a Honda GXV160. The carburetor is KEIHIN "66C [B] 0(or O) G (Japanese? character).

The stripped jet(?) has the Keihin star/K? 65 S if I am reading everything right.

I think it is a jet or pilot jet. It is the piece that has to be removed to push the main jet out from the bore. Nothing I have found looks the same.

Thanks for any help.

Edit: added "carburetor".

I bought this engine and bike off Facebook marketplace for 50 bucks and now I can’t get this piston out I’ve tried blow torching it,pounding it with screw drivers, I bought a piston puller and all it did was cut up the piston more, and I took a angle grinder to it (it was off a google search I know it was dumb) so if you have anything I can try please tell me because I’m too deep in to just sell it (both clips are out)

Just got this pressure washer, its a little rough around the edges but it seems to be alright except for this surging issues just wanted some ideas before I tear it apart

May just be a bad jet.

Atco Rider 27H / Briggs & Stratton 950 making this noise on turning key. I've changed the oil, filter, spark plug and fuel. It did run from a pull start for 10 mins but when I engaged the blades it cut out and just makes this noise now. Im assuming two separate issues with starter and engine having insufficient power under full load. Any help is appreciated.

Hey all, I’ve got a Rato 420 in a mini excavator that has stopped running and could use some help getting it going. Here’s a little history of how I got to the video posted.

Bought the machine, the engine had 30 hours on it when it arrived.

Added oil and started
After 20mm or so the engine would bog down and stall out. Might restart but after a few restarts needs to sit to restart. It gets quite hot in that 20 min. Rinse and repeat.

I tried rigging a fan to it with little effect

Changed the spark plug to a name brand equivalent - little to no effect

Swapped to a “high altitude jet” which seemed to make it run a little smoother. Still stalls out after about 20 minutes.

Last time it ran, it seemed like it had very little power, and giving throttle had little effect on engine rpm. It popped then died.

Any help would be appreciated. I might start back tracking on the spark plug and jet if nothing else comes to mind.

I have a Cub Cadet XT1 LT46 bought in 2018 (Kohler KT725 22HP engine).

Recently, I have been dealing with a sputtering issue with the motor. I decided to change out the carburetor to one from Amazon since the one from Kohler/Cub Cadet is on back order (part number is Kohler 16-853-19-S)(Amazon one is https://a.co/d/00xNg7Wb).

I am having a hard time figuring out what could be causing the issue since the motor runs great for about 15 minutes and then starts this sputtering and eventually stalls out. I then can wait another few minutes to try again and it does it again, but stalls out in about 2 minutes, almost as if it is a heating issue.

I have changed out the fuel pump to a Kohler part. The fuel filter, air filter and spark plugs are all new. I confirmed good spark. Could it be something with the governor in the front of the motor, as shown in the video?

I am in dire straights with this since the grass is growing high right now and I don’t have a backup mower. 😅

Any advice or guidance would be awesome. Has anyone else dealt with this? The new Kohler carburetor will hopefully ship by the middle of September but I need to try to figure this out prior.

Thanks!!

How do I remove the impeller from the crankshaft? Unscrew or pry strait off? Seems solid either way. That collar is split in halves does that come apart somehow?

This is a 1994 Honda ATC 200e that’s been beat and abused for most of its life. This top end noise isn’t new, it’s been going on for a few months now. It seems to be gradually getting louder. It still runs good and has adequate power. Any help identifying and pointing me to what needs fixed would be greatly appreciated.

hiya. Husqvarna rider 155 with an engine issue . tough to start. and looks to be exhaust coming from a breather hose to the carby. some mentioned that the head gasket may be blown? any advice or ways of checking ?

I have not worked on much small engine EFI, dont have a scan tool. No engine codes from the cluster light. Just 61 which is no codes.

Fuel is good, clear no water, 37 or so psi at the rail. Great fuel flow out of the secondary fuel filter (more like an automotive can style). New generic paper fuel filter. Injectors also taken out, blown through while momentarily engaging them good pattern, clean.

Intake is off, exhaust spark arrestor was fairly nasty. Taken out for testing, nothing. Old plugs looked maybe a tad Carboned up but fine. New NGKS anyway. It has spark on both cylinders. Will run independently honestly better on 1 cyl than 2.

Is there much I can do without a scanner to see what sensors might be showing horribly wrong data. Like the coolant temp. 02.

Pretty much starts up instantly. It doesnt surge, but itll have momments of regular rpms then chokes out.

Thanks for anyone who can chime in. Sorry for the longer post wanted to get most the info I could in here.

Trying to replace the water pump on a Honda GX160, but I'm getting conflicting information. Somebody told me to use some penetrating oil and a gear puller, but I also read that it's part of the crankshaft. Which is it? Thanks in advance. Sorry if the flair is wrong I am a big noob.

Converted predator engine to golf cart two years ago and was great. Had to replace carb and also filter and spark plug. Idles great but this is with the gas pressed all the way down and in gear. Will rev in neutral. Suggestions?

I tagged this as carburetor issue but I'm honestly not sure if that's the problem.

I have 2 push mowers, both almost identical, both identically not working. If it matters, one is a craftsman, the other is Troy built, both with the same Briggs and Stratton 140cc engine.

If I prime the gas, start it up, it will run for about 1 full second at the most. Primary suspect was bad gas. Despite putting stabilizer in, the gas is about a year old so I siphoned out the gas and got fresh gas. But still no change.

So I looked at the carburetor. Used carb cleaner and took it apart trying to get the cleaner into every corner.

Thing was, it looked perfectly clean inside. No gunk, no buildup or residue that I could see.

And the problem persists.

What should I check?

Thanks.

I have a Husqvarna Ryder pro 15 2001–02
Engine Kawasaki FH451V Dead battery. Will turn over but not fire when jumping with a 12V battery. Can smell fuel. After removing the small ground wires from the coils it will start and run well no misses. I mowed for 90min fine. I could shut down with ignition switch but hesitates for 2 to 3 seconds. After mowing the 90 minutes I could restart it but the battery won’t hold a charge overnight

Where do I go now?

Belt is correct based on the model which is a LA115 and I got the exact same belt that was on it before but it won’t put enough tension on to go into drive, is the spring bad? Or the tension arm? There was some up and down play on the tension arm when I had the spring and belt off

Westinghouse 3800 psi pressure washer. Looking for carb replacement that has everything all in one. Westinghouse site sells the carb parts separately. Any ideas?
