Need Help, new to World Formula!!!

[Andrew Pachon]

So I just bought my wife a World Formula kart and she is super stoked to start doing track days with me and a good buddy of mine..

 

A friend hooked me up and told me that I need to change the gears to run 16-63 for Mac in McMinnville, OR which is where it will be running.

 

What oil do you guys recommend for these karts? How often do you recommend I change it out?

 

I understand it runs on 87 pump octane. Additionally, it does not require pre-mix.

 

Please share any advice or info you can to help me get my wife up and running. Yes the kart does run.

 

Thanks in advance, and any help is very much appreciated.

Before it got taken apart and cleaned and re-shot Day-Glo Pink.

 

After – Floor pan is still out. I shot that too.

Head over to Portland Karting Association and contact Michael Schorn. He is a longtime WF racer and will get you going in the right direction. Great person.

Run 93 octane. Pump gas works fine! I use the Briggs 4t oil and haven’t had any problems. A lot of the guys I race with only change there oil once per race day But I change it twice. Oil’s cheaper thaan motors! Great reliable motor. Have fun!

 

[Rick Brown]

also, I run 16oz of oil

[David McDowell]

You need to be very careful about the oil. Stick with they same synthetic compound that has always been ran in the motor. I have one motor which I run Cool Power in and another which I rung the Briggs 4T since these were the oils that the builder started with when I purchased the motors.

Pump gas works perfectly with these motors if you can find 83-87 octane that is ethanol free that would be the best.

 

Have fun. But I assume after a few track days you will be itching to start pack racing.

I can’t say thank you enough for all the information you gents have shared.  I am exited for my wife to take her kart out this coming week. It was her wedding present and she is all amped to get out there.

David, I did post the exact same question(s) over at PKA’s site.

I always ran Redline 5-20 in my wf with no issues but like others have said stick with what ever was used in it previously until you rebuild. We also did a lot of testing with they amount of oil used and found zero difference in power from 14oz to 18oz so you may as well run 18oz to be safe IMO.

So I completely understand hat you all mean by running what has been used until the next rebuild. However, what if it was run on two different oils.

This kart was run on the lighter wt oil for races and the thicker wt oil for practice and track days.

With this in mind, what all do you gents recommend now?

[David McDowell]

Andrew do as you would like. I’m just going off the information my engine builder gave me. I respect his opinion since he works directly with Briggs and has dozen of national championships with the motors.

[Andrew Pachon]

David, thanks for the added information. I am going to give 14oz a go.

To go along with ‘New to WF’, can I assume that the Animal Rocker Cover Breather Adapter fits on a WF just the same?

What they are saying is some oils dont mix well with others and will lead to engine failure if not completely flushed prior to using new oil. I believe the briggs 4t is one that does not mix well with more traditional oils. Definitely want to double check. 16 oz is recommended.

[Andrew Pachon]

Hey Gary, and all the rest of you gents that took the time to respond to my post. Thanks can not convey how thankful I am to have you all as resources to help me get my wife up to speed. She took her kart out and had an absolute blast.

I drained all the oil after it was warm and also used my compressor to help rid all the oil I possibly could and filled it with Redline oil. IT sounds pretty crazy compared to my shifter.

David, I don’t understand what you mean by the Animal Rocker Cover Breather? I apologize but I am new to WF so this is a pretty steep learning curve. If you could clarify, I would be greatly appreciative.

Are you guys running a temp monitor on the head?

Thanks again for everything and all the information.

I _think_ the breather kit is the same for both engines.  I honestly didn’t realize how inexpensive the kit was or I’d have bought it a long time ago.  I’ve always gotten away with just stuffing fuel line into the included breather hose and routing that to a catch can.  I’ve only had a problem with oil coming out of there on an oval track.

[David Cole]

Thanks Craig. It’s a great little part to make the engine look better. I just have to dress up the gatorade bottle I use for the overflow HAHA

[Craig Drabik]

Indeed, I have a 20 oz Pepsi bottle on there right now.  Funny thing is I’ve got two real catch tanks sitting on the work bench and haven’t gotten around to installing them yet.

[Craig Drabik]

Just a followup here that that IS the correct part for the World Formula.  I ran one this weekend.

[Craig Drabik]

I’ve always run Cool Power medium green, 15oz.  I usually change every weekend.  If you know what oil was in it before it might make sense to stick with that.  Various oils seldom mix well.  Otherwise I’d fill it, run it on the stand or a few practice laps, and change it.

93 octane pump gas, no premix.  Check your club’s rulebook, they may have a spec fuel or a certain gas station they want you to use.

[Finch Guenther]

I would think two different weight oils would be fine. For example 0-20 Redline for qualifying and 5-20 Redline for racing but Im not sure I would run 2 different brand oils. This is just my personal opinion others may have more input on this though.

There isn’t any more power to be made with lighter/less oil (at least on my dyno). I would definitely stick with heavier weight and don’t change it around.

Also, unless the engine is really fresh you will be money ahead to go through it sooner rather than later.
