Here we go again. Its acting up worse this time!

Well today it ran like 90 year old legless man. I got it running long enough to move it into the back yard, and that is where its staying until I figure some more things out with it.
May be buying this kit to redo gaskets ( http://cgi.ebay.com/ebaymotors/ws/e...0785226848&viewitem=&sspagename=STRK:MEWAX:IT )
what do you guys think of it. Will it be fine to just freshen up the motor some? Hopefully get it back up and running. So i can go to some shows and cruise ins this summer.
