Good call Mech! I have never seen this happen but generally the first thing i do is check the oil and if its over full or smells gassy or feels just not oily, change it immediately. Glad you got that sorted out.

That should not have fixed anything but diluted oil, it should still run with gas in the oil just doesnt lubricate well and toast your engine. Generally gas gets into the crankcase when the needle and seat is bad and lets gas seep by and into the crankcase.

Good advise. Thanks for the info, i am not really expierienced with that particular engine with automatic valve adjusters.

Those old Suzukis are great machines, they did them right.

Agreed! Thanks for the info. Great information there from research, not found in any books.

Yeah dealers are like that, i think their philosophy is " if you have enough to play,you have enough to pay". I would try taking the throttle body off and cleaning it, there is probably a sensor in there that gets gummed up over time, certainly wouldnt hurt, and you might get it done without taking it off, i have done it that way, but you can clean it better by taking it off. You also might try first Berrymans B12 Chem tool in the gas, its a very good fuel injector, carb cleaner available at Wal Mart and most Auto Parts stores, i have had good luck with that cleaning up gummy injectors and throttle bodys.

Thanks for sharing, looks like a fun time. Im getting a little old for that kind of riding but like watching it. 👍

As i recall the motor controller, a very expensive part and no aftermarkets available, is activated by the CDI, and it absolutly has to have a good ground to operaate correctly, including the fan, the controller itsself may be grounded through the CDI, not sure, i am having trouble relating what i know to yours because the one im more familar with didnt have a fuel pump. I think what you are doing stripping the wiring loom and checking is the best way to find it, you can throw expensive parts at it all day long and still may not get it. You have worked hard at it i havent been much help, but good luck.

Yeah it does sound like a bad switch, you can take them apart and clean them up, but for this level of inconsistency i would just replace it . Aftermarket ones are fairly cheap and i havent had any problems with them.

I thought you might have already done that, just thought i would mention it. This is a tough one. You may be right about the fan controller, i would check all the connections very carefully at the controller and CDI for good contact. Is there any other problems going on other than fuel pump?

Agreed! None of these problems should cause it to only run for a few seconds and quit.

I would change the oil , change the fuel filter, check the differential oil, if really black or milky looking change that. Also replace spark plug.

Photo has been removed, what part are you referring to.

That sounds like piston ring blowby, how long since you did your top end job. If you are using synthetic oil it takes longer for the new rings to seat.

Which one had no resistance, primary should have very little maybe.3 and secondary should be between 6 and 10.

Sounds like a bad relay did you replace it and still wont work.

You have been busy, sparlplug coil sounds weak, should be between 6 and 10 OHMs, what does the book say about that. . Do you get a good spark at the plug.

Good you got it going, rebuilding the original has always worked best for me, and yes, no ethynol gas, i dont use it in any of my small engines seems to destroy rubber partts and initiate rust on the steel parts.

Valve clearance is rather concerning, was the valve adjusting screw loose, it should not have changed that much in 650 miles.Unless previous owner adjusted it I would reset the valve clearances to spec and see if that helps. That would definately affect compression because clearances could actually be less than zero. Not really sure how you fixed the computer or what was wrong but that could also be limiting your revs electronically. Never had much luck at fixing computers, when something goes out it could actually take out another sector then it hard to diagnose.

Many things could cause this. If it is oil fouling maybe rings or valve guides, hope its not that. If it is dry powdery fowling it probably flooding. I know its fuel injected, the only thing i can think of there is replace the injector, but before doing that i would run some fuel injector cleaner through it and see if that helps. The other question would be how does it run, good, sluggish acceleration, jerky accelertion. What im getting at is to properly diagnose i need a little more information on how its running. There may be other electronics involoved that control the fuel injector.

Good diagnostics, glad you got it up and running.

I havent had a lot of success with JB weld on exhaust , doesnt like the high heat, but it will hold for a while, if still having problems they make putty for exhaust, also doent hold up well, the constant jaring of the machine loosens it and it falls out. Not much help, but that is my expierience.

Tanks do get nasty, being plastic helps a lot, not rust ot corrosion, and they clean up very easily. Good job getting it going and painting the racks, coming along nicely.

Just read your post #31, i did like the Atlas, Tiguan not so much, i would have looked at it closer but my wife wasnt interested in VW. I could have swayed her into it , but i was not that interested in a 4 cylinder in a vehicle that large, but they are all going in that direction, as far as the turbo charger, i dont think they are as durable as a NA engine, may be wrong. i didnt really want that The start stop feature on the outback seems to work good, im just not used to it, i can see how it would come in handy on bumper to bumper traffic in large citys. Im kind of old school i drive 20 yr old cars and i think they are fancy, all i need is a steering wheel and a shift lever and im good to go.

I figured you had probably cleaned them while apart ,just thought i would mention it. I usually start with the mixture screw 1 1/2 turns out from seated and adjust it until its running the best usually end up between 2 and 3 turns out. There is a tool that makes this easier Amazon sells several versions this is the one they recommend: https://www.amazon.com/Carburetor-Adjustment-Screwdriver-Motorcycle-Snowmobile/dp/B0BMTG92J7/ref=sr_1_2?crid=3UOBFMYX0H15D&dib=eyJ2IjoiMSJ9.TkpaU_CuOz3g4qBIsE0V3kMWh2LbJ8B--hRZEtRfDG6FSmQaIMAT_bCclJwC3rMnlvUzYzqd3kfdzlVuSTgdmgMuzklKuPmVjr-telZpWZ7oufONGBcix2tI-Rwb2C_ziP_sMT2DT7g3C8s0XdkPuIEQC912TUXCxnpQSyz9Bia0ezgQQFdmCzIAmYA24MGkC7qF6doGOWJFnrzv44euu_ifx_hXcVP3zMKQndygysd3y0i9_T3lYxf6MyfyiRp5xSS5B4n_kc2vi5fQWTjEfBK5ahg-fwd4528zGtdYGuw.dK0eY_t2Q-uOOZ41B5km52z_Z3V1Rmb8ydWD4HfRYh0&dib_tag=se&keywords=atv+adjusting+screwdriver&qid=1712854997&sprefix=atv+adjusting+screwdriver%2Caps%2C122&sr=8-2
