alright so i took apart my ka24 twin cam 16valve engine to replace the valve stem seals and we successfully replaced the valve seals and we put everything back together (camshafts and the engine in general) at first when we got everything back together it wouldnt crank it would try to turn over but wouldnt crank up all the way... the timing was messed all up so we set the cam shafts to the correct position and the distributor set to the #1 spark plug and had it set on tdc and we got it to crank , it idles now but it has trouble idling and when we push the peddle to give it gas it only revs u to almost 1000rpm, all to gether we replaced the valve stem seals and the top timing chain tensioner, need help to get it started any other timing positions to try? anything? thanks

That's not normal. The timing should stay where you set it. If I remember correctly my brothers KA-T skipped timing and ran like crap for a week till we reset it. We ended up setting it right, and it ran just perfect.... For about 7 minutes then we crashed it on the test run cuz this huge f250 was in the middle of the road trying not to hit his mailbox. Needless to say, cresting a hill at 90mph while dodging a ford equals hitting a ditch, 2 trees, and required me to be life-flight from being KO...

Your best bet is setting the timing again and then hand crank the engine once and check timing again.. IMO :banana:

Hand crank 2wice,needs 2 revolutions to be beck to where you started. Also how are you setting the tensioner? if it's like my sr, you have to turn the motor counter clockwise 1/2” to unlock the latch then rotate clockwise and is set.
