Still rattling after I did a carb sync.

[Lastwachter]

There is a knocking type noise which seems to be coming from the valve area. I saw that when carbs are out of sync that this can happen. Since I had not done this yet I was hoping it was the culprit.

However after syncing it, it is still there. The noise does change with the adjustment of the idle screw and carb adjustments. The noise seems to decrease when I have pretty far out of sync at times but doesn't sound great when I do have them synced. The sync may not be the greatest out there, but it is pretty darn close.

However, since the carb adjustments do see to change the noise, I figure it still relates to it.

Any ideas?

Most likely the primary chain.

Primary chain slap is most noticeable from the right side rear of the engine. Not the valve area but sometimes hard to tell the difference for the first timers. Was it making this knock before you did your belt change and valve adjustment? I would go back and recheck everything I did previously.

Yes it did this previous to purchase. I do plan to go back through and check everything I have done.

Check your timing also. Out of time condition can cause a knock. (Not referring to timing belt)

I had to use a make shift led flashlight timing light. So it wouldn't dim only shut right off but after doing it, it still knocks but it also runs much smoother! Thanks!
