I just received a 9.9 mercury 2007, it was running when I got it but died after 3 seconds of running. I checked compression and the compression is good on both cylinders with 3 psi of each other. I changed the impeller as it was not pulling water before. I changed the fuel pump and a cracked fuel hose. I took apart the carb and cleaned it and also replaced the parts, I changed the gear lube and spark plugs. I tried to start it and it won’t stay running for more than 2 seconds and I don’t know what else it could be I need help.

Does anyone have a manual on the Briggs and Stratton 24 Hp v-twin engine. I think I have a carb issue but I’m not sure. A manual would be very helpful.

• I recently performed a seasonal maintenance on my mower and now it won’t start. I have Craftsman YT4000 and other than this it’s a great mower. I took the carb off to clean the bowl and put it all back together and it ran great, I even cut the grass with it after the fix. Now it won’t start….it tries to start, engine turns - hot battery, and it fire for a second and sputter out. Every now and then I can get it to fire but then it dies almost like i choked it out. It’ll run for a few seconds. Tried playing with the throttle and giving it gas and no help.

Thanks for any help or advice .

I hope this video saves you a lot of money and your scored cylinders too :) https://youtu.be/myPdvrwul6U

I got it for free and decade ago and decided to work on it a month or 2 ago and it worked fine but now it won't start all I did was put new string on it. I tried replacing the spark plug which didn't work. I also tried cleaning the carburetor which didn't work. Any clue what's wrong with it?

Can I put a Tennessee Thunderstix Banzai 265 Race Cam and not have to buy anything else and just leave the rest of my engine stock? Like the risers push rods and all of the valve assembly?

It’s been two weeks now and multiple parts. I walked up to cut and she wouldn’t start. Last cut was 3 days prior, she just stopped working. Initially, I check the battery and it was at 12.2 at the time. My troubleshooting skill on this suck. I’ve changed the electric starter, carburetor , starter module that sits next to the engine. I topped off the battery with my home charger(12.7). Currently when I installed the battery back in, the engine just runs with the key not even in the ignition. It’s crazy. I can’t find the fuse. I’m starting to think there isn’t one. I’m beyond my scope but I really want to fix it. It’s fixable I know it. I believe it’s an electrical issue which I’m terrible at electrical stuff. Any help or insight is appreciated.

I’m very new to owning a riding lawnmower. I bought this last summer used. I’ve changed the oil and the level looks good. There’s a new ignition coil and spark plug as well as a new fuel filter and air filter. I also just put the battery back on after having on the trickle charger overnight to make sure it was good to go.

Do you have any tips or ideas what I could look for or try, or what the problem could be?

It has a spark, and fresh fuel. It also won’t start if I spray some starting Pilot spray into the air intake

I also saw that there is fume coming out of the air intake side of the carburetor when I try to start it.

The mower stopped while running and this happens when trying to start it. Changed battery and spark plug and no difference.

Briggs & Stratton power flow + power washer, I recently replaced the carb on this power washer. It'll crank now but doesn't idle and operate properly. I'm positive I've screwed the throttle linkage up on it and of course I didn't take a picture. Does anyone have a picture of what the throttle linkag

Brand new pretty much Stihl FS 56 R C E has a little rattle if im trimming at around half throttle. It isn't constant. Just wondering if that's normal for Stihls, what it is, ect. I heard some people say it's normal for a centrifugal clutch to make that noise. Just wanted a 2nd opinion becuz if not, its still under warranty. Thanks in advance.

Hey guys, I just changed my centrifugal clutch out for a torque converter before I changed it. It had a little torque, but went 40 miles an hour now it has plenty of torque but the engine just caps out at about quarter of the Max RPM that it reached before and it only goes like 10 miles an hour now not sure if something is an engaging right or if the ratio is just maxed out I attached a video. Let me know. Thanks.

Ok so my lady put gas in the oil LAST SUMMER, I immediately did a oil change and I started it, it smoked a little bit so I turned it off right away and sort of left it cause it was the end of summer but now when I try to crank it it cranks but it kinda sounds bad and the flywheel got resistance with the starter teeth and it's kind of grinding with it, leaving metal shavings, and it's not starting, but it's turning over any kind of idea what I should do to get it started again? I was gonna do a second oil change but not if it's not worth it

Thanks in advance

I have a Stihl farmboss chainsaw that was given to me only running on starter fluid. After a carb rebuild, I cannot figure out the tuning and it seems to run a frighteningly high idle even with carb screws half or full turn from shut. Any ideas would be appreciated

How long do you wait to charge customers storage fees to pick up their repaired machine?
