V spek like to run fat on the bottem. High speed and the midrange @ 2 oclock / is all ive ever changed. I have 2 and not much diffrence between them.

Thanks guys, ill try that stuff, but first i gotta get a new one of those plastic pieces that goes around the carb neck where it goes into the engine case at. I tried to get the carb off yesterday and that took forever, plus the little plastic thing was melted onto the case b/c we had to heat it up to get it out.

When i took apart the engine the other day i noticed that the top of the piston was a little burnt and black, does this mean i was running it too lean or is that normal?

A brown color to carbon color is normal. thats some deposits from the engine burning oil.

how many gallons are on this mill?~

about 4-5 maybe

how does it run now? still blowing plugs?

ya, havent ran it since i asked that question, but ill try it out soon.

If it still blows plugs id still say replace the rod

The rod was fine, i checked it. I think it was running a little to lean

did you measure it or just eyeball it?

Eyeballed

trust me your eyes are not a micrometer. even a few .001's of an inch is out of spec, throws off your compression ratio etc...

" I eyeballed it" Wow.... yeah that should be accurate. (Christ)

yeah...Hahaha.

If you've got micrometer eyes and a digital readout, go be an engineer.

I am going to be an engineer,and i know its my tuning because my bros engine, which i also tune, has been doing the same thing. Theyre running at like 250, you think i should richen them up a bit? Im resetting the needles so i can start over.
