Story begins here.....
My 7port has been great all season till last Sat.. I started having the lean bog that I have been seeing. This is the first time I have had any tuning issues. It was not running hot just leaning out after a few minutes on the bottom. I spent all day checking anything that would be related to a lean bog (fuel line leaks/pinches, tank leaks, air leaks, idle gap, air filter, plugs, needle O-rings) I made adjustments all day and when it came time for the B mains I thought I had it ready. Same issue no matter how fat I made the LSN.
Anyway I got home and tore down the engine completely. The only visible issue I saw was the O-ring that is in the bottom of the carb insert neck . It was trashed. I just want to replace this and see if that was all it was. I do have a v-spec carb on standby but I don't want to give up on what has been working fine all season.
Sorry for the novel. I don't post alot but read here everyday. Shout out to Brian
TIA

A Main has the orings in stock just picked some up myself. also several GO dealers here in this thread can help you out w/ the o rings and newer needle. Brianr34 is great he is my local dealer and willo get whatever you want at great prices. i had same issue w/ my carb oring being torn up. just use some GREEN SLIME when installing the new oring in the block and make sure to seal the carb/block w/ some high temp silicone. wouldnt hurt to replace your needle orings too. new lsn does NOT come w/ oring so make sure you buy 2!!
