Odd they are specing 15w40 in it...wonder if they have cleared it with briggs .....one more thing...i may be wrong but im not sure any of the big manufacturers (briggs,kohler,honda)have certified and will warranty there engines to run on lp/ng ....obviously these guys are doin it but may be taking the warranty/risk on themselves instead....gonna do some investigating...

Same basic thing here..I have these in front of some kubota zb600-c 2 cyl diesels for almost 3 years now..no issues...the green "diesel" version.....oriellys has them in stock....bout 60 bux.......power wire...ground wire...good to go....just tryin to help....

The ones with the cage around them are very thin and a are basically considered "one way" or one time use totes...that's why they are so readily available used and cheap....for something more substantial look at something like the APR type of tote...new ones are kinda pricy but u can get used non certified "out of date " ones pretty cheap...and will last you years. Guaranteed....I have many of them that I use for chemical storage that are 12 yrs old +....just tryin to help.

Donaldson GO42544....go to the donaldson site and check that out..there is lots of info and specs....probably get the whole thing online for bout 100 bucks and the air filters are super easy to find....just trying to help..

I run z602(2cyl) and d902 (3 cyl)kubotas on pressure washers..3600 rpm from the turn of the starter switch....I have removed the air filters with them running and the intake noise is deafening and is way louder than the exhaust and everything else running.....the air filter housing assemblies are donaldson type and are all plastic and quiets down the noise immensly...u hear the exhaust way more and the intake noise is almost non existant...ill get a part # for ya...should easy to order online...

Yep thats it....and oriellys is where I get them lol....

If your looking for a  reliable 12v low pressure pump that is diesel specific. Look at mr gasket brand...they are green colored for diesel....I have 6 of them on rental industrial pressure washers that run for hours at a time...no problems...about 60 Bux and can get st most auto parts...ebay has them also.......

LOL well its over $1000 now and Im done.. 

I sell new equipment that comes standard with Briggs Vanguard engines as the standard engine, Kohler and Honda are the option engines I can order.  I  only stock units with Kohler Command 18-27 hp horizontal engines in my business. If somebody insists on a Honda or a Briggs I will order it for them.  Honda V-twins IMHO are under powered for what they claim, expensive to fix and are hard to reliably get parts for. Have seen lots of valvetrain/cam gear failures with them also among other things. Only thing I have an issue with on the Kohler is a fuel pump failure once in awhile. My 2nd choice is the Briggs.... NO complaints whatsoever on those except keep a spare starter solenoid around cause the stock one sucks but a big screwdriver across the solenoid posts will get you running in a pinch ..The application that these engines are used in are industrial hot water pressure washers.... WOT from the turn of the key until they are shut down.   Just my 2 cents on the aircooled v-twin stuff I work with on a daily basis. 

I may have the flywheel you need, PM me your email or phone # and Ill send ya a pic.

Check out his 1005 setup ... I think it's the same but I could be wrong. ...
