On a non fuel injected ATV, is the petcock is left on prime, should gas flood the oil case?On repairing a gasoline flooded oil case, what are some things to consider?
Good day and welcome to Just Answer. My name is XXXXX XXX I'd be happy to help you with your problem today.
That depends on if that is a vacuum operated fuel valve or not.
You typically always want them off, but a vacuum operated valve only flows fuel when the engine is cranking or running.
Prime is used to fill the carbs after a carb service & the carbs are dry.
In cases of fuel over flow that is most often because of debris in the float needle or a stuck float.
Other instances that allow for fuel over flow is gravity fuel valves that are left on, & vacuum fuel valves with a worn diaphragm.
Petcock has 3 setting. on ..prime...reserve... was left on prime and flooded oil case
When that diaphragm wears out fuel flows all the time. That will push beyond the float needle, wash out your engine & lead to oil contaminated with fuel
In order to rectify that you need an oil & filter change.
A carb service & typically a new fuel valve diaphragm.
shop wants to new petcock and carb rebuild...can i get away with petcock only?
you have a bad diaphragm or a debris stuck in the float needle.
you also do not need a petcock, they are rebuildable, just but the diaphragm.
You need the carb service for 2 reasons.
to inspect the float needle to be sure that isn't also the issue
this particular petcock is not rebuildable so shop says
and to clean any crud brought through with all that extra fuel
let me check on that real quick.... I think your parts guys is full of stuff.
as far as I can tell they are completely rebuildable.
since you have yours on your tank, check it out, it should have 2 or 3 pieces all stacked together like pancakes, there is the lever, & its mount, with sometimes what looks like the spacer, those are the air passages & then between that & that back there is your diaphragm...
that is usually the problem.
its looks like yours is only 2 pieces..
remove the 4 screws to disassemble & rebuild.
obviously since yours is in your hand you can see if that is possible or not.
one second please
it looks like you'll need to remove the lever/face to access the 4 screws that hold it together.
Suzuki does not offer the diaphragm on their retail parts list but a dealer should easily be able to get you that.
And that is why the parts guys likely said that.
atv carbs are close to motorcycle carbs correct?
same exact thing
just usually a single carb
shop wants 700 for carb clean, petcock, tune up and fluids
trying to budget fix this
what does the "tune up" include?...
& are they talking all fluids?
all fluids and fliters, plug
no valve adjustment?..
i was think that is stardard after carb clean
a tune up basically is the carb service, new plugs, air filter service & valve adjustment...
fluids are a separate deal & parts are always extra.
I think $700 is high but if you are dealing with a dealer that is $100/hr, well that is easy to get to $700. And that is just part of the cost of ownership.
not dealer just shop
If you are mechanically inclined, & have the Suzuki service manual, I can walk you through most of that.
$700 seems excessive to me for an atv tune up & fluid service.
A coolant flush included?...
i do have both, but since it was a craiglist buy i wanted a professional look...it ran ok before i took it in...just wouldn't idle and was sitting for awhile
then i flood oil case ...then really want professional look before disaster
I will keep you in mind for a carb clean
ok, then you should be in ok shape.
I don't think the shop over estimated what needed done, but maybe went a little nuts on labor. I think you need most of that stuff done & if it was a cheap cl buy, you might want to throw $700 at it just for the peace of mind of getting it right to enjoy the season, then you keep it up from there on out.
The service manual will walk you through everything but the carb rebuild.
Thank you, keep me posted of you need anything..
