do you always get a shiny wet spark plug from letting it idle to long or only when its overly rich does it do that?
wet plug??

If the idle is incorrectly adjusted then it is possible that the plug will be wet.
Rich needle or rich main should no cause a plug to be wet after prolonged idling. That is if the idle adjustment is right.
An oil rich ratio can too be the culprit for a wet plug at idle.

my idle is set perfect though?? i did it exactly how yo said to before, also i mix at 32:1
My plug was wet an fouling alot.. not at ideal but while i was iding in general..
It was my float postion actuall... make sure its set at 22 mm maybe... its worth try

Hmmm:-/
So it only returns a wet plug while at idel?
i would say have you plug chopped is your jetting right... but blaaster just said that it shouldnt matter at ideal. an hes a really knowledgeable guy.

uhm i would lean with yes idk why its doing it but as long as your plug chop comes back fine then your jettings correct
your air tight no air leaks then i would ride it
But idk that puzzling that u get a wet plug at idel i would put a fresh one on for the next ride an see what you get
U could have just a slightly messed up mixed im not doubting u can mix 32-1 but s*hit happens

Float height is 20 - 21.5mm on a stock carby.
Is the B8ES plug causing you hassles, like missing or fouling?
If not why worry.
Each time I pull a plug after prolonged idleing it is black and damp, but does not affect the running.

i could have messed up the mix a small bit but if i did not by much, it runs great starts great everything is great it just gets a damp plug after idle, i will not worry about it though unless problems start to occur. engine is air tight, b8es is fine, it was fouling plugs a shiz load at a 320 main jet but i have in a 290 now and its great
oh i thought that it was suppose to be set a 22 mm thats what mines set at should i drop it the half inch?
Messing up the mix is bad, even by a little bit.
More oil = less fuel = lean = heat = boom.
Less oil = more fuel = rich = cool = wet plug.

well im out off all that i mixed now so i will start fresh, im going riding tommorow 8 hours away so i will get gas and oil there
Whoo wait im not doubting you at all one bit blaaster i trust everything you write on here....
but this whole time i been thinking ass backwards.... i thought
add more oil= rich=cool=wet plug
i thought that adding a splash more oil would be more on the safe side... i got a mix cup i mix precicley but just saying...
An so oils that run at 50-1 should be cooler then 32-1
An i seen u mix lean i guess u would say a little oil rich right? so your blaster would run hot or do you just have your jetting set up to hadel that amount of oil.
Lets take a 32:1 mix as a control.
If you change to 24:1 you get an OIL richer mix which will help increase compression, but add very little to cooling.
The problem now is that as you have added extra oil, this takes the place of gas. More oil = less fuel = lean = hotter.
The premix is now oil rich , but FUEL lean, which will burn hotter, hence can fry the piston.
If you change from 32:1 to 24:1, you must increase the main jet at least one size to compensate for the lesser fuel in the premix.
I have at times used premix oil concentrations to adjust my AFR to suit elevation and temperature changes.
Most of the time I run 25:1 because it suits my riding style and conditions, but if I need to compensate for cooler conditions sometimes I drop in some 32:1 to give me more fuel in the mix.
I hope I have not confused you, if you need detailed info toss me a PM.

It is not the content of oil that determines the heat, but the amount of air to fuel!
Some oils can be run at 50:1 because of their composition and lubricating properties.
A 200cc motor should be run at 32:1, or greater oil concentration, unless the maker of the oil states in the instructions to use it at 50:1.
like amsoil dominator i used it at 50-1 (says on the back to do that) an everything was fine...
So basically i was confussing oil rich/lean
with fuel rich/lean i belive...
So basically what ever i am jetted for if i do my plug chop with a 32:1 oil ratio in the tank dont switch oil ratios... am i right?
