Thanks Star! Understood that dealer restricted info is hard to access for DIYers. Figured I'd ask anyway for a ballpark range by carb type Walbro and Zama. (y)

Much better to READ what "not to do" than have actually having done it! If you are a DIYer and know it all, then you should expect grief from the pros on this site if you cannot do the 3 L's - learn, listen and list (serial # and model #)

Yes downloaded all the great info on both Walbro and Zama carbs. However the chart info is not there. With no chart (unless you are a pro) a DYIer usually will : 1. Seat H L and turn out T 2. Turn out L in 1/4 turn until she starts and idles at suggested RPM range turning in T 3. Turn out H...

This is great. Can you please post something similar for Walbro carbs? I has all the relevant info including T settings and RPMs. I have both Zama and Walbro carbs and a general chart like this would be great rather than seating H L and then backing out 1/4 turn at a time! I've looked and...

I put Tomcat green mouse blocks on walls tops and floor bottoms inside of shed. Another lesson I leaned the hard way, if you are in cold weather climate and storing for the winter-- on your last use for the season WAIT before putting in the shed. I make sure I leave the rider mower in the...

As a DYIer describing the method of 2-cycle carb tuning is like describing to a kid how to ride a bike with no training wheels. If you keep at it and keep practicing eventually a light goes off! To help me know if I'm getting warm, I use a tach to measure rip-ems, which the pros gauge by ear...

Possibly, however in my case I don't think so (see my longer reply below)

Good points fellas. Correlation does not necessarily equal causation... My neighbor is an old geek engineer like myself who is handy. I think in my case it was a stuck valve that I verified when I removed the bowl. The dark mixture was probably residue just sitting at the bottom of bowl...

What do you guys recommend for pressure washer pump protector? My pump does not have an oil resevoir like some do. The $15 bottle you can get at HD seems like a scam. Thx

Drained bowl. You could see gas mix in bowl was like dark turpentine, but bowl much cleaner than was expecting. Valve was stuck, so used carb cleaner and compressed air and got it moving again. Cleaned the bowl and then gave it a go. Started right up. Thanks!

Yeah Is there a chance the needle valve is just stuck open and bowl float & needle valve just needs to be cleaned out? I found the carb assembly item 210 in the diagram for $68 on ProPartsDirect so that seems a little more reasonable. :unsure: Thx!

on it thx!

Did some more research and found it could be the float needle valve stuck. Would that be the 1st thing to look at?

Got a Subaru EA190V power washer S/N EA190-1479542 Lent it to a neighbor and was working fine. Got it back, started her up and noticed fuel shutoff was closed. So shut engine down and turned it back on. As soon as I turned fuel shutoff on, gas started pouring out of carburetor. Seems like...

TobyU very well said. Thanks for sharing all of your findings based on 1000s of engines! Happy New Year!

Ahhhh thanks for the insight did not know that it's common. After doing both head gaskets, was surprised how dry one was .vs the other.

Yeah been changing the oil/filter every season with 2 qts of synthetic and yet have had to add any. Maybe I'm being anal and/or looking for something to tinker with. Probably should find something else... :rolleyes: Thanks!

Thanks for the tip! Can't hold a candle with a combustion engine pro. :) I don't want to fix it if it ain't broke. I don't mind tinkering with it, but as you said watching it until it starts acting up may be best for an old DIY guy like myself. I learn a ton on this website from folks like...

I've thought of that too, but then wouldn't the other cylinder have oil too? Given the pictures I posted before/after when doing the head gasket replacements? I was reading that blue smoke on cold startup that clears could also be from leaking valve seals. The mower gets through the season...

Update fellas: I ran her the rest of the summer for another 30 hrs before winter. Scoped both cylinders-- #1 had oil deposits on piston and #2 was clean (pictures attached). Once on startup she gave some blue smoke, but it cleared quickly during 10 uses before end of season. I'm thinking...

OK fellas here is what I measured: I also checked the entire distribution box wire connections from generator: No load measurements: constantly fluctuating between 107-112v 61.2-62.1 Hz Running Drill :106-110V Running 1500w small desk space heater: 111-113v Something is wrong with this...

(y) yes was planning to do drill, extra hair dryer etc. I was implying that the master electrician who installed the 30A inlet/gentran switch would have tested via connecting to inlet and e.g. turn on the breaker to garage and test some stuff with neighbor. I'm surprised how a master...

Thanks Star useful info from you and ILENGINE. Was hoping to get some info from the Pro manual side as Generac is pretty much closed to DYI. I guess a better way to test a brushless is to connect it to an inlet to your house and then turn on some breakers and then measure AC voltage. My...

Interesting ILENGINE. I'm going to put a load on it and then measure AC voltage. Neighbor was testing with a LED lightbulb and stated it flickered and then blew out. He tried and Alexa device and said that blew out too. I've seen low fat LED bulbs flicker on regular power so that probably...

Star picked up on the wire diagram Rev E it called for a 47uf cap, yet the replacement part # lists 28uf. Should I try finding a 47uf cap and do the same test? Thanks!

:unsure: I measured the out of the alternator on 2 different MM and got 3.5v and 3.7v AC A 5v +/- 2v AC should be a indicator of alternator working. Measured voltage regulator again and got 27.5 uF Put on my dunce cap. I was hoping to get to root cause, but still scorching my head. Any...

DId some more poking around on help sites, for a brushless alternator: troubleshooting test is to disconnect capacitor and connect MM to the 2 alternator leads and measure running AC voltage. If it measures 5v it's good and capacitor is bad. If not 5v then alternator is bad and Generac...

Yup Star beat me it's brushless. Anything to try to eliminate the rotor and focus back to voltage regular which I confirmed its within 29uf spec??? Thanks!

Added my own gas and started up Generac and she ran rough (3500 rpms) for 5 min then settled down. Tach reading 3660 rpms at full throttle no load Measured fluctating readings of 99-110v all at 60.x-61Hz Head scratcher, any tips on what to try next??? For comparison fired up my own generator...

It does... was playing with new toy settings and placed into wall outlet by couch and got a 121v @ 59Hz reading. If it's around 30Hz, you saved me from draining gas (not much in tank). I'll add some and let it run a while and see if it settles down and then take another reading. Thanks for...

Star got ahold of a MM that measures capacitance... 27.52uf so it's good. I asked neighbor more questions and he said the engine ran "rough" and he and electrician could only test generator with 1/2 throttle??? I'm gonna pick up on ILENGINE suggestion and go to engine side. Neighbor said...

Ahhhhhh light shines on marble head.... Thanks Star!

Thanks ILENGINE I did notice the choke was on 1/2 way. Will put a tach in it and measure. Pulled off the OG84440101 It's 28uF part not 47uf as wiring diagram stated. Diagram has Rev E ECO chain so I wonder if 47uf was a phase in part. This unit was built in 2009 Measured with 2 different...

Interesting... I did find the part on Generac website, my bad as I was using "g" instead of G. Let's see what Generac support says on 28uf .vs 47uf as well as getting to root cause. Thanks again Star!!!

Good catch Star!!! I pulled the pn from the parts list. Where did you get the info 0G84440101 is 28mf? I'm going to call them on Mon. Thanks!

Generac Model: 0056260 Serial: 5452944 (don't know the build date) Unit is basically/looks new, however it only outputs 110v not 120v and (while testing) blown out LED bulbs and Alexa devices. Trying to help a neighbor who wants to give to me and go buy another generator. Pulled the schematic...

Can someone please point me to a PDF of the B&S 440000 Series Service Manual? I have a 24HP B&S 445677-1188-B1 OHV Twin engine. I searched online for part number 273521 however it points me to a PDF for 276781 which is for single cylinder OHV engines. Thanks!

Finished the other head today and fired it up. Was able to clean head in 2/3rds of the time. Plastic blade scrapers help pick off the big stufff, but scothbright pads, acetone and time is all you need. ;)

OK fellas, put her all back together today & checked the torque settings (twice). I did end up adjusting the valve lash both intake/out could not take .006, .005 pretty tight and .004 with resistance. Started right up. Big thank you to StarTech, berstmobile1 and slomo for all the tips, spec...

Pros .vs Joes... Don't expect to see one of these under the tree this XMAS :) https://www.enginebuildermag.com/2019/08/cleaning-components-with-baking-soda/

:ROFLMAO: Yeah do it right, with you 100% I did it over 3 days... at times I was sitting on the garage bench trying to distract myself as I sang Time in a Bottle. My 1st 2 fingers went numb. :)

bertsmobile1 your exactly who I was thinking... :) I'm plugging away in my garage and the Mrs. will not be happy if a chemistry experiment goes sideways and I win a Darwin Award . Big difference between "Pros" and DIY stiffs. ;) Oiy!

:ROFLMAO: thanks, yeah got a bit anal on the clean-up, but want to do it correctly. To me your a "shop guy" while I'm just a grasshopper.

Yeah I was also thinking paint thinner, but did not want to try something not recommended by the shop guys. Window cleaner (ammonia) is interesting too. Thanks for the tips. I said to myself no way a shop guy is going to clean a head and piston for 8+ hours :)

OK slomo, yeah know what you mean. I've used oven cleaner with those nasty fumes. I'll give heat a try on the other head gasket project. Will let her sit on the black driveway while I have my morning coffee. It's in the 90s here in the U.S. Northeast, then rinse & repeat.

You weren't kidding slomo... cylinder head took ~8 hrs, the piston took about 1.5 hrs and was much easier to clean using plastic scrapper and scothbrite pads. Started with Seafoam and then switched to acetone which seemed to do better on carbon. Is naphtha any better? Waiting on a seal-o-ring...

Thanks berstmobile1 for another tip. I think I may as well do the other head gasket as well. :) Probably has a slow leak as well given plug looks a little oily as well. I now have a scope to look in side.:)

Yeah the factory bead spread pretty good and took a while to clean up with plastic tool and fingernails :)
