Yeah the 12mm. I just bought the whole tensioner set off eBay for $9. But I've gotta take head back off and get another guide anyways. Was hoping to fire her up this weekend. Oh well :(
I have to order a new timing chain tensioner bolt. Spec called out to torque to 29lbs and it snapped. I'm guessing previous owner tightened the hell out if it. Was a B to get loose.
It's an 87. I got there and he had another guy coming that offered $100. So I did what I think anyone would do and I matched it. $100 and I loaded her up just in time for that other guy to show up. He was a bit pissed. he drove an hr. I win lol
