what exactly are you wanting? I'm at work right now, but I have a repair manual at home and can look it up for you.

I have a 97 300 EX and i'm having a problem when i just hit the gas it's fine but when i hold the gas the motor breaks up, but it idles fine. All i did to the motor was put new rings in it now this problem start. Any help would be thankful.

It Is Mechanically Timed..... (No Distributer To Turn & Time It) The Only Way It Could Be Off Is If You Took Out The Cam (Which It Sounds Like You Did) Or If The Cam Chain Jumped A Tooth Or 2.. The Only Way To Check It Is To Take Off The Valve Cover Get The Motor At TDC & See If The Marks Are Lined Up On The Cam Gear

you need to take the head cover off not the valve cover idk why it would be the timing tho sounds like your limiter is kicking in way to early??could someone please explain this to me?
