'nother "left in prime,gas in oil" type question

Tank was dry, I added about 3/4 gallon, put it on prime started it up, let it run, shut it down and left to run an errand, came back 20 minutes later, smelled the gas and saw the puddle, dropped to my knees raised my fist and yelled "NOOOOOOOOO!" I can't beleive I did it.

So I'm changing the oil (which was fresh), my question: if I didn't run it, do i need to change the filter (which is also relatively new)?

Its a stuck float on #4, I still had gas in the tank 9so I didn't lose much), the puddle was from gas draining out of the airbox; my breather element and air filter were both dry. I know gas could be leaking into the cylinder and dripping into the sump, so is the filter still clean?

BTW, as this is not the first time I've done this, I'm thinking of upgrading my petcock to the one that reads "res" at 9 o'clock, "run" at six o'clock, and at 3 o'clock it reads "NEVER,EVER,EVER, PUT IT IN THIS POSITION WITHOUT TAKING IT OFF THIS POSITION, STOOOOOPID!"

 

You can re-use the filter provided it isn't swimming in fuel. Remember gasoline is a petroleum distillate (it is distilled from oil) and small amounts of it will invariably end up in the oil anyway so I'll bet that the filter is engineered to stand up to fuel exposure. Hope this is a convincing argument. Any other takes on this question?

 

reuse oil filter ok

 

I know its the float on #4 because when I open the airbox,took out the filter and shined a light in, the boots from 1,2,and 3 were dry and you could see the gas coming down #4. I figure if its dribbling back to the airbox then its also dribbling into the cylinder.

 

As long as you never started the engine, the oil pump shouldn't have pumped contaminated oil into the filter housing.
I'd leave the filter alone, but I'd change out the oil before running it.

You might get by taping on the #4 carb while in prime with the end of the boot showing.
I'd tap it while it's leaking to see if it stops, THEN, I'd change the oil.

Be CAREFUL how you tap, the carb housing is a soft alloy and can break easly
Let us know how you come out. :? !

 

uhm, what position are you supposed to leave the bike in?

uhm, feel rather silly here , but what position are you supposed to leave the bike in, there's not really an off, so I'm not sure....

 

"ON" is the park position. This position requires engine vaccum for the fuel to flow.

 

Hi.

The vacum on my carbs has been seeping a little juice in the run position since I fitted the pet-cock re-build kit (or what fitted from that kit). I have the carbs off again but don't seem to have any floats sticking though one is a bit slow coming down. I have lost about 2 litres of juice and I had to drain a lot of oil away a few days ago, I though I had overfilled with oil but now know different. So I have to cue the vacum and change the oil I have not run the bike so from what you blokes say the filter should be OK but should I try and drain the middle gear?

Have been fiddling with the vacum and while the tank is still it seems to be holding but if I tip the tank back and forth a tiny amount of juice is passed.
Is that usual or should no juice flow at all.

In run, with no vacuum you should have NO leaking past the petcock!
Still or not.
I'd check out that petcock it's not right and you can tell if there is gas in you oil by simply smelling the hole where you fill the oil

Good lucl

I've had the petcock to bits a dozen times now and this is the best it's been. I've just tried with the tank back on the bike and it seems to have stopped dripping juice, the carbs are off so the vac hose isn't connected. I have changed the oil, though I could not smell petrol in the oil it did'nt smell right. I tried to find the middle gear plug to drain that as well but even armed with a picture I could'nt find the thing.

I got a spare box o matches

1 "drip" or 2 i should think is not too much a worry , but as mentioned tecknikally there should be none.

i wish it was the same for Presidents!

I've never drained the rear plug on mine either.
I think just changing the oil and filter (if needed/contaminated)
should be suficcent.
If you've got that petcock to stop leaking when in RUN you should be good to go. I'm presuming you rebuilt that petcock with a kit of new seals right?
If your needle and seats are good you should be in business.
You mentioned that your carbs are off, are you going thru them?
Be sure to blow the passages out with compressed air and be CAREFUL not to loose any of the small parts.
Be sure to pull the jet out of the body of the carb that the needle jet goes into and clean out.
good luck
