Hello all,
I need some advice for some issues that are really confusing me. He we go:
I am currrently finishing up my build and adjusting my webers in the process. I noticed that when I installed my windshield and hood I now here a multiple ticking sound coming from the trans tunnel area. I am pretty sure if the noise was always there I would have heard it. I would like to say it is detonation. The sound comes in around 2500 - 3800 RPm and my A/F meter is indicating 10.5 - 11.2 mixture (rich condition)
. I have tried jetting the webers so that they are even more rich than what they arlready are
and retarted the timing to initial 0 degrees with a 25 bushing. The noise is still there. I also have tried dumping in some octane booster with the same result.
One funny thing I noticed is that if I gradually increase the throttle the noise is not heard. I was currently running the 2 blue springs in the MSD distributor. So , I decided to use the larger silver springs to see if the timing was coming in too fast. This help alittle but did not solve the problem.
My compression ratio is 9.5:1
One other finding was when I retarded the timing the noise was still there. But when I bumped the timing from 0 to 15 degrees the noise got better. When I first noticed the noise my timing was at 12 degrees. SO it seems like the more timing I added the better the result with the large springs.
Can someone shed some light on this?
One other thing I am running a lighter flywheel and lighter pulley if this makes a difference.
Is it possible that my assembly is too light?
Please help getting fustrated
