Has any one found when changing the timing gear sprockets, that the cam sprocket dowel pin is in the wrong hole in the cam making the timing mark on the sprocket 180 off. There are two holes in the end of the cam. I think someone during engine assemble back in 1990 was setting up a head scratcher.
 
I wanna say the set I did in my 91 was like that. Im thinking its the sprocket thats wrong, not the cam or its installation. Been quite a few years and I could be mistaken though.
 
Well that makes me feel better, that someone else ran in to this . I thought the cam as there are two Dowl pin holes in the cam. If the other pin hole was to be used the timing marks would’ve lined up. I tried to change the the pin but couldn’t remove it.
 
I have rebuilt my TB. Fuel pressure is now 15.5 PSI @ 2000 RPM. It’s 1 lb more than spec. Is this going to be a problem? I hate the thought of removing the the TB again to get at the adjusting screw on the regulator
