i have recently had the timing bumped up and he set it a couple different ways,it ended up being around 22 degrees.i also shimmed the gov. springs and now it sounds like it's popping above 2500 rpm's what is going on here??it is pulling good.
i don't know,would it be advanced too far?he had to use the spillport method.we couldn't find the specs on the pump it says 847 i can't find anything on it
i think just under a load and he said he's sure it's between 22 -25 degrees and its not really a pop as much as a cracking sound or something it's hard to explain i guess it sounds similar to a jake brake????
