ok
i know this has been gone over, but i cant seem to find the right answeres for my situation,

ok, i have an old rebuilt motor i pulled 2 years ago (ran when pulled) , its been sitting for a while outside and the inside, wasnt very pretty, lets say there were rusty spiders in it when i finally started cleaning it up,
now ive gone to the work of cleaning it out with wd 40 and other misc oils i had sitting around, and i swapped it into my car once my motor blew
what happening is it wont start
it try,s sputters but it just wont get there, pured tons of gas down it, to try and clean it out, but just wont go,
have a bottle of atf sitting in my garage, should i pour it in let it sit over night, and try to clean it out and start it tommorow,
i just dont know, i know it gets fuel, and spark, is it flooded, should i clean my plugs

my main question is if to pour in aft and how much and where, and if it worked for you,,, thanks

autopaul

oh ya, i did the timing while the engine was being cranked over,, its dead on, and also it did almost start one time, but just didnt stay going, it eats up tons of gas though, could my compression just be ****??
i hope i can get it fixed otherwise its time to buy a daily driver

I've got a pretty much stock 12A that you can have if you want to come over to the island. I'd trade ya for one of your sweet bumpers.

ill have to make one first, any help on fixing the problem would be much apreciated though, ok since nobody said anything i went ahead and poured a litre of atf fluid in the intake and turned the engine over once, just to get the fluid in there, im gonna let it sit over night, then drain it out, and see how it goes, any tips much apreciated, i know some of you have had these problems before, so give me a hand will ya.
thanks

ok, she still wont start unless i use a quick start spray, i know my fuel delivery is good, so does this mean that my motor has just been sitting too long and will never run again,? i hope now any advise please

anybody

does it idle or run after 2000 rpm? if it does, then your idle circuit is clogged.

First, check tyhe plugs to make sure they aren't wet with gas. They don't fire well when flooded badly from my experience. Remove all 4 plugs and crank the engine. Don't addd gas or starter fluid aside from the carb. Make sure you hear compression and see a mist out of the plug holes. Crank a few times you clean out anything in the combustion chamber. Re-install clean plugs. Try to start it.

Sounds like your internal seals are stuck. If it sat for a long time, chances are the seals inside are rusted by humiditity or carbon locked. Keep trying the ATF technique, I know it has worked for some people, but the engine won't last long w/o cleaninig it up. Oh, and it smokes like a mother F-

My advice is to yank the engine, buy a soft seal re-build gasket set, and re-build the motor, but check the compression first to confirm. Another way to check the APex's is to hand crank the motor so the seals are visible in the exhaust port. Push them in to determine if they are springy or stuck. Make sure to check all six.

Also make sure to have some new clean plugs in. Hows that cap and rotor? Wires?

Good luck.

Mine used to do the same thing. It had a bad vacuum leak, and a bad accelerator pump. I chaged my cap, rotor, spark plugs, wires, and found the vacuum leak and it seemed to fix it right up (still had a bad accelerator pump, so I had to be easy on the throttle up until 2500 or else it would die).

autopaul

no it doesnt run at all unless i pour a whole bunch of gas in, i know the carb is good, it was just running a different motor last week, i took all the spark plugs out numerous times and cleaned them, also put the plugs lined up on the fender, each one was firing great,but each time i took them out they were pretty badly fouled with fluid,
but it still only starts when i put lots of gas in, what should i do, i let it sit overnight with atf hopefully that got all the carbon out, im not gonna put any more in, could the engine still have too much atf in it and fouls the plugs,
i know its not flooded cause the only way it shows any traces of life is if i pour lots of gas in, more than the carb could ever supply at once,
any help is much apreciated, thanks guys

What is your fuel system setup? Pump, fpr, fuel pressure, are you running a return etc? Are you sure you are getting enough fuel?

Have you done a compression test?

autopaul

no compression test, stock pump right now, but ive been running stock pump for a while with the other motor, just a bit of bogging up high, no idle problems,
i took out the lower plug on one rotor and did an ear compression test, it sounded like a good health pshh pshhh pshhh same results on other rotor, funny thing is that if i spray instant start in the rear rotors carb inlet it will sputter and fire, but if i spray it in the front rotor inlet it does nothing, shows no signs of life, does this mean my front rotor is dead? i know its getting good spark but is it just getting fouled in the front,
just an idea

autopaul

holy crapppppppp!!!!!!!!!!!!!!!!!
thank you all for your help, this thread is such a useful tool,
turns out i accidentally plugged fuel from going to the carb by turning an inlet regulator screw, and it wasnt getting propper fuel, this things got way better compression than my last motor, even after sitting for 3 years, oudoors!!!
holy crap now that im deaf from running the motor without any exhoust whatsoever, ill just say, the atf trick really works, this motor was crap before there were rusty spiders crawling out of it when i got it, and now this thing is really cleaned up, just to all of you out there that wanna give up dont, i was about to but then i decided to giver one last go over and i figured out the problem, thanks again,

autopaul

ok new problem its running, idles fine, its a bit quieter after all with the muffler on than my last motor, or im deaf, but it doesnt rev nearly as quick as it should for one, and it backfires out of the front rotor when i rev it up, so my motor is dead after all? anything else i can check??

Do a proper compression test. That will tell you if the front is weak or not. I don't know if your engine is good or not. I gave up soothsaying a long time ago, however, trouble shooting over the internet seems like it sometimes.

Since the engine has sat for so long, it may just take a bit of running to loosen the seals . Take it out and run it through the gears.

Great advice. Also pre-mix a tank of gas to help get oil back in those hard to reach places. Don't use synthetic pre mix BTW.

I still think you have a seized A-pex. Just my .02.

Rev it high and hard to knock things loose and allow oil in.

Change the oil and filter again; too, now that it has started. I'm sure there was a lot of crap (like bug legs, etc.) in there.

Congrats on at least getting it started. Good luck. Keep us infored of your progress.
