I have checked the timing on my 88 2.6L and am unable to get it above 4 degrees before the distributor runs out of adjusting room. I have the distributor turned all the way toward the firewall and it is still running rough. It almost dies when I turn it back the other way. I can't find any vacuum leaks that might cause it to run rough. I thought about the rubber bushing having turned on the main pulley and I have a gut feel like it is just out of timing. compression check done by recent service shop is good.
I recently bought a new Delta cam and want to install it. Question: Can I set it at TDC and install the cam and reset the distributor without pulling the main pulley and everything else involved in that? The classical Haynes manual I have just says "pull it all!" (alt., air pump, PS pump, Radiator and fan shroud). I have done it before and had to find and getting that main pulley bolt was a real PITA. I had to heat it with a torch and get a new (used) pulley and lower timing cover.
