F22a6
After inspecting my engine and doing a compression test i got some odd numbers... 150 exactly on all 4 cylinders, but my girlfriends cb7 has ~205-210
so i dont think anything is worng with the engine because all the cylinders wouldn't have the same compression.
We noticed when looking at it that the distibutor was all the way back towards the firewall and any other position has no bottom end and has a bad idel. This made us pull the spark plugs and get the engine to TDC, once at TDC we noticed the cam shaft arrow is not perpindicular to the engine head. if i where to turn it one tooth back the cam arrow would point 90 degrees off the cylinder head,... which is actuall pointed at the windshield because of the angle of our engines
so my question, is the arrow supposed to be pointing vertical, or vertical related to the engine (90 degrees from the top of the cylinder head).
Because my car feels like its missing some torque and i know my distributor should be closer to the middle of its range?
Any sugestions, im thinking about moving the cam one tooth back so its perpindicular to the head and seeing if it makes the engine feel right... i know the engine feels wrong, but it dosn't feel broken... it is very healthy.
also more background the engine has been rebuilt, but my guess is that i caught the very end of the compression stoke instead of real TDC, i used a long extension to find TDC this time, thats how i realized the cam arrow was off.... but i am sure the whole bottom end is in time with itself i am fairly positive the cam is my culpret but i would like some feedback.
- im thinking i can loosen the tensioner slide the belt out... move the gear and slide it back on.... if not i guess im going through the pains of a full t-belt job including the crank pulley
if i do it this way is there anyway to lock everything else in place.
