I am using no nitro,full castor self mix fuel.My JBA and SK engines runs well with OS 8 and A3 and OS 4 stroke,but none of my engines runs well,beyond half throttle with Fox miracle.Idling and low throttle is good but never gets full throttle .

Turk, your engines must be unusual or your fuel is of poor quality, the Fox Miracle plug will work in any engine from a Saito .30 to a Supertigre 4500. If I have any problem with any engine I put a Fox Miracle in it and it works a Miracle.

But how can they work well with OS 4 st.or OS #8 on same fuel?(I have 7 engines).None of them works with Fox.

Turk1:

Try nitro instead of Raki in your fuel!

You are right.Some bandits using same fuel to make some illegal drinks and killing friends and others,sometimes including themselves.But Im sure my methanol is not different from yours.Are you sure,Fox miracle will work better with nitro getting higher percentage?

Turk, I run 5% nitro in all my two strokes, the Fox Miracle is the best plug for the MDS engines too.

The only fuel I've ever used is homebrew methanol and castor and I've yet to have any engine act up with any half way reasonable plug. I'm not fond of OS plugs because they're too short for just about all engines and even Enya plugs have the same problem although they seem to last forever . My current favourite plug now is the Taipan 4 stroke plug which gives no rev change at all when the power is disconnected in any engine I've tried it with so far.

Taipan 4 Stroke plug ... good Aussie gear

Often overlooked, but performs very well. My Saito 56 and 91 seem to like them.

They must be good considering that all your engines are inverted down there. I wouldn't mind trying a couple.

I'll see what I can do [8D].

PM me your home addy Hobbsy ...

Is there a chart like Flyboy Dave showed for OS for the Thunderbolt plugs? Global doesn't seem to give you a lot of info about the glow plugs and where best to use them.

How would a Fox Miracle plug work in a Moki 1.35? I plan on runing 0-5% nitro. Thanks Capt,n. PS I just got back from Florida...so its time to do some more engine work!!!!!!

I liked the Fox Miracle plug in my Moki. Not as well as the OS F. If i ever run the engine again i will try the Fox 4-stroke plug not the miracle plug. I was running Wildcat 5%

Where can the Sonic Tronics 4 cycle glow plug be purchased? I would like to try one in my 1.35 Moki engine. Thanls Capt,n

$8.95 for the Saito

I know that a F plug is considered hot because a four-stroke plug has to be hot because it ignites every second stroke but I have my doubts about the theory when it is used in a two-stroke. When an OS91FX is used with a tune pipe and 15% nitro without an extra head gasket it is notorious for pre-ignition and blowing plugs. Using a No.5A (or now a No.10) or an F plug does help to solve this problem. If it were so hot would it not have aggravated the problem?

Sorry Cap, I didn't see this, the Fox Miracle works well in an MDS 1.48 and 2.18, also in a SuperTigre 3000 and 4500. It was a little hot for my MVVS .91.

Not hotter, just better heat retainage, that is they keep more of their heat through the exhaust and intake stroke. Some brands of four stroke plugs are actually fairly cold. The K&B 4C for example will seem to be a very bad plug unless you are using 20% or higher nitro. But unlike a cold two stroke plug it will maintain a low and smooth idle. If you fly C/L with a four stroke and venturi, no throttle; you will not even need a four stroke plug.

Hellow Down Under!! Where can a person buy the Taipan Glow plugs. Thanks Capt,n

Taipan Glow plugs are as popular as kangaroos in Australia but not in the USA

Maybe, Jim, that is because [link=http://en.wikipedia.org/wiki/Fierce_Snake]the Taipan snake[/link] is more common there... Like rattlesnakes, or OS glow-plugs are in the USA...

There are also other Taipan hobby items in Ozz, such as props.

That's correct Dar - the Taipan snake is EXTREMELY DANGEROUS & EVEN MORE VENEMOUS. My neice lives in "taipan country" just inland from Cairns, she's had a few close calls from snakes lurking in unexpected places [&:] I'm off to visit her - the neice, not the snakes - in Sept so wish me luck. Then lurking in the waters around Cairns there are nasty saltwater crocodiles, marine stingers aka box jelly fish.......yep, life's a real hoot here in Oz [8D]

But seriously, I did a net search of well known (to we aussies) hobby outlets & I can't locate any Taipan Plugs either [:-] Hopefully Downunder can chime in here & point us in the right direction. Where are you Brian ?

Had a taipan (coastal) in the garage the other day. Looking real closely at some guinea pigs.

Reared up like a cobra when I nudged him out with a pool cleaning pole (extended out !!)

(Things that make you go Hmmmmm)

Now, for information about taipans that are real grouse for glow engine fans :

Yep, Lion Electronics but I believe they've stopped making the Cox/Norvel glowheads now.
Oh, and the Taipan (snake) is 200-400 times more poisonous than a rattlesnake.

Bone....[link=http://www.tnet.com.au/~lion/Dealers.htm]here's[/link] a list of all Aussie hobby shops for Taipan stuff.
