This is my first post, as I am new to the site. I have had my '92 xj for about two years now and the idler gear went out last summer. Over the last couple of weeks I have stripped the bike down and pulled the motor apart. I got the gears replaced and everything put back together, with a lot of help from the site
so I thank all of you for that. But now that it's all back together, when I turn the motor over, plugs #1 and #4 are showing sparks but #2 and #3 are not. I've been looking all over the bike like crazy but can't find anything. Any ideas?
