I have not had carbon build up on the intake port before on any of my OS motors previously. The carbon rubbed off pretty easily and the top of the piston is fine.

Any ideas?

Thanks,

I just noticed the front page ad that I clicked on to get the above link says with both heads but the link it took me to(above)does not say that,just 2009 version,heres hoping.

Just for future ref does your site have the paypal pay later option?

I think the 2009 version comes with both std and turbo head button.

I paid $289 as well for the 2009 version. I got it from rc-toro.com using the their coupon. They have very good service
