Ok...I just filled up with gas tonight. Kinda worried, as I don't know if the previous owner was using the OMP or premixing. I removed the air cleaner cover, and didn't see any oil going in where I could see. Is there some other way of knowing if it's working? Keep in mind it's nighttime...so dark, flashlight is my only light ): And I am not completely familiar with where everything is.

So how do I know if it's pumping oil, and how long can I go without it, temporarily if it's NOT getting oil? If not, then I need to premix, and for that I need which oil?

Please help...I drive 60 miles tomorrow minimum over almost 2 hours...I'd like to keep my car running.

Should I be able to SEE the oil, or do I need to unplug a tube or hose to see it?

 

If you see oil in the clear lines that go into the carb, then it is probably working.

If your not sure, you could just dump in some 2-cycle oil. It wont hurt anything to have it run a little richer for a few days. (it will smoke if the OMP still works)

 

With the car warmed up, look at the two little tubes in the carb as you rev the car at about 3k rpm. You should see a little oil drip out of those tubes. BTW, the FSM has a more precise way of measuring the output but the above method should give you piece of mind.

 

Ok, revved the engine not sure to what...tach doesn't work. Anyhow, didn't see any drips at idle, revved a bit, saw drips from 1 tube (passenger side?), revved a bit higher, probably 4k? saw drips faster from same tube, slow from other tube. The OMP is on the passenger side of the engine, correct?

I found in a manual a way to check output by removing tubes and checking volume over 3 minutes or something. But #1, I dunno what tubes to yank. #2, I have 2 arms, it's dark, and don't have an accurate measuring device. #3, My way seemed to give me the result I was looking for.

Now is that 2nd tube supposed to drip slower, might it be clogged, etc? Not sure even how the carb works exactly...could it be stepping up the amount of oil, delivered to both rotors as revs increase, or does 1 tube each go to a different rotor, meaning one of my rotors is getting less oil?

At least I know I'm getting oil. That's a good thing (;

 

One rotor it getting less oil. It could be a clogged line or a malfunctioning OMP. I would premix until you can sort it all out. Rebuilding the pump and replacing the lines should make it as good as new.

 

I'll have to find the OMP first. No idea what it looks like, or where it is; saw on a manual that its on the passenger side for the 13B, I assume the same for the 12A?

Premix...tank is full, or nearly now. No problem dumping oil in it, but how much, of what?

 

The pump is located below the air-pump and in front of the exhaust manifold. Mike Lowe at http://www.loweperformance.com can set you up with a rebuild kit. His web site is down now but just give him a call at (941) 924-8597. He can hook you up.

The premix rule of thumb seems to be 1oz of 2-stroke oil per gallon of gas. I wouldn't worry about your current tank of gas but the next time you fill up, put about 16oz of 2-stroke oil in the gas tank. I purchase my 2-stroke oil by the gallon at Walmart. It's cheap.

 

So currently it's not working right? Ugh, asked on another board (local) and someone said it's working right. Never know who to believe when you're new to this stuff.

So both tubes should be going equally? I'll try to locate it soon, and consider getting 2-stroke oil to supplement my low (?) oil supply. I would assume I don't need the full amount into the gas, because oil is going in? Or should I put the entire amount (1 oz per gallon) and have 1 rotor getting excess?

 

better safe than sorry, id rather run rich with oil than lean, cause rich wont cause any damage

 

Yes each tube should dispense equally. The only sure way to know is to pull the lines and measure the ouput of each. You might want to consider doing that.


You probably don't need the full 1oz/gallon. But like BigJim said, it can't hurt.

I have a fully operational OMP and I premix 10oz per tank full.

 

I'll get some 2-stroke oil at Wal-mart hopefully tomorrow. Gotta get a plug for the bell housing (mine is...MISSING!) probably from the dealer. While I'm there I'll order the last gasket or 2 that I need to complete my MX-6 head gasket change so it'll be ready for the road again.

Ok, 1oz/gallon of gas. Had to look back for my post to find what kind of oil to use.
