Hello
Before too long I will be doing a "how NOT to" post about my reconditioned engine install, but before that tale of muppetry and misery is unleashed, I have the latest and most horrible sounding noise yet encountered during the process. After a few sessions of breaking in (stationary) and generally messing around / timing / carbs etc, the engine was sounding quite okay. Then I noticed a transmission type noise which was a little worrying. THEN forget that, a new and worse noise appeared from the top end of the motor, probably front near distributor - I am sure this only just materialized after some time running the motor. I recorded a couple of audio files from around the distributor area which seems like around the sort of region it is coming from. But it's always hard to tell. Those are attached, I had to put the two audio recordings in a zip file so that has to be downloaded and extracted I am afraid.
I have a rattly noise that is not there at idle but comes on maybe at 1500-2000rpm, and seems to come on a tad more also when the rpm's initially drop after lifting off the gas. It is definitely not supposed to be there. In my minds eye I am imagining a loose chain.
If I have to disassemble this, I might lose the will to live. I spent a fortune and this was professionally rebuilt by 215 experts D&D, so it is basically brand new. It has 10W-40 in it, per D&D recommendations.
Any suggestions?
