I think that's a 5/8" plug. Use a 5/8" deep socket.

Any ideas on the size yet? I want to get this ready to go and have had no luck. 5/8, 3/4, 13/16, 11/16 are a no go.

18mm deepwell or plug socket will do the trick.

Use a 5/8 deep socket. I know it works. Otherwise, look for a stone at the base of the plug.

After digging, I found the socket that works. Now, do I need to get a spark plug from Kohler? Napa guy wasn't any help.

Well what Mystic Sizing did you use ?

napa has to have a plug......or get one for you

Wow, that's a nice sale price for that $4 plug.

I guess PT Barnum was right.

It seems to be my luck of the draw. A couple of years back , I got to buy an expensive plug for a trimmer too. That one went to the landfill. Fortunately the riders in our family take same 'ole same ole' plugs! This one isn't a normal plug. It has a smaller body than the plug I thought it came with. Absolutely no fuel in the float bowl for now.

I have bought the Kohler plug too as I didn't see much available for that plug. If this helps others, the Kohler plug is 1413206S / Champion 8815. Maybe there are now, I haven't looked. On your not getting fuel, these had a habit of the float valve corroding to the body on the early ones. Best to clean it up and put a new kit in it.Kohler says the plating is better now. You can get by with cleaning up the old needle as well, touch up the ribs on the needle w/ a file if you're on the cheap. Flush all the old fuel / water out and you're good to go.

I hope that this isn't a sign of how my equipment is going to treat me this year. Thanks for the info.

Eeep, I thought Kohlers were a good engine maker. The carbs sound horrendous. As for having a proprietory plug, that is just plain stoopid.

There is nothing really wrong with the XT's. I don't see much difference between them and any other Chonda. In the spirit of heck- I think XT's, Honda's GC , MTD's import all use the same flywheel keys even. I would rather work on a GC anyday.

It runs like it should again. The needle was a corroded mess, so I left the dealer with a kit. Do I assume that the corrosion was from storage? Would an addition of 2 stroke oil to the gas help?

I would suspect untreated ethanol gas did that damage. Use Startron in your fuel.

Ed: If your fuel has ethanol additive and your store your fuel for more than 30 days you will continue to have carb related fuel restriction issues and fuel line deterioration . As Bay has advised a fuel treatment / conditioner will be required to reduce the potential harm that ethanol has within Small Engine fuel circuits . Stabil Products for prolonged storage are quite helpful , along with the use of Fuel conditioners such as Lucus / Duralube or if possible the Startron Product , which a Forum Member previously has earmarked as a very sound product for fuel treatment of Gas and Diesel Engines . Goggle it and if available utilize it accordingly . Unfortunately I have not been able to locate any locally , but the tributes look very interesting indeed .

I don't know if a light 2 cycle would hurt really, but there are hopefully better products for the job. I may just order some Startron on my next Stens order. It looks as though that there must be different strengths. Some specs 1 oz to 6 gallons of fuel and some 1 oz to 16 gallons. I've been using the marine Stabil as rdaystrom I believe pointed out could be an improvement over the regular Stabil. Hopefully you won't have issues anyways w/ the new needle.

Here is a link that might be useful: Startron

There seems to be interesting claims made at that Starbrite website. How much real experience does anyone here have with it?

Yes as Tom suggested it was rdaystom that originally brought light to the Startron Product . I think only Baymee may have utilized this product ? I would if it was conveniently available in the Great White North lol .

I haven't been able to find Startron around here either. Their site says that WalMart carries it but my local one doesn't.

Locally, it sells for about $7 per bottle. I googled it and found it at an Ace Hardware in Brooklyn for $4 a bottle, so I loaded up.

It's too soon for me to know how it works. I'm trusting in the testimonials for now.

I sell those little pouches of Fresh Start from Briggs. I thought that I may put some of the little Startron too. The larger bottles are really a better buy, but the shelf life is 2 years. The Fresh Start doesnt have a shelf life. I know that other stabilizers get little crystals in them when they sit. I don't really know which would be more effective. I wonder about some of the claims too. I tend to think that any of them are effective for at least 6 months for 10% eth gas, which is all we need typically anyways.

Has everyone forgotten about SEAFOAM?

"Has everyone forgotten about SEAFOAM?"

Nope. It's still my fuel cleaner of choice. I just wanted to try the Startron. Seafoam goes in the first and last tanks of the season. MMO in every tank throughout.

Shuzam ! Found a local Dealer for Starton . Will be picking up a bottle this week . Can't wait to trial it on the Ole Diesel . Yes Seafoam is a proven product along with Lucas , but have to give Rdaystom recommendation a try ! :)
