Hi fellow Zonie ;-}tbrookes2000;343968... gone to PREMIUM fuel.. ...I have oiled the throttle cable. ..She DOES seem to run perfect in the afternoon when its hot ([B said:Im in Arizona[/B])...
I have been building and riding MB's here in Phoenix for close to 2 years now and the summer heat can be brutal on these 2-stroke air cooled motors and the rider as well you know ;-}
1. Premium Fuel.
Excellent choice, that's all I run, not because the higher octane helps, it is just typically cleaner fuel with less Ethanol, that **** is not friendly on our gas lines and does not burn near as well as gas without it.
At 4 months you should be plenty broke in, mix 32:1 (1/2 cup quality synthetic 2-stroke oil to 1 gallon of gas).
2. Oiled the throttle cable.
Not a good choice, especially here in the desert.
You don't fix a sluggish throttle by putting oil in the cable, Graphite maybe but never oil, it will soon be worse than it was and may cease to move at all over time.
Too late now, the throttle cable is the one cable that has two ends so you can't pull the cable out that most likely wasn't the problem to begin with.
Good 'throttle snap back' ranks right up their with dual brakes as a major safety thing. The LAST thing you want if you take a spill is the throttle sticking open.
Just like no new build bike leaves my shop without front and rear brakes, they don't leave with a sticky throttle either. I know that sounds a little anal but I have a little higher set of standards for my builds than most.
My solution is pretty simple.
Never use the gas tank mount plates to hold your throttle cable, any cable for that matter, it pinches it causing friction in the cable.
Then when I assemble the throttle I put a little dab of grease (not oil) between all the moving plastic parts that touch inside the throttle as well as a light smear on the handlebar the plastic throttle barrel rides on.
3. Iridium Plug.
I don't know about other motor brands but any Skyhawk motor will take an Iridium plug, I love the suckers, it's like a instant boost you can actually feel and I keep them in stock.
With summer here in full force now an 8 is your best heat range bet for them.

Hope that helps ;-}
