Those sound like the early 87 same as 86 carbs. These are the ones I am running. I'm jetted with 63D's main, 14's intermediate, and 34's(or 36's not 100% certain on which) for idle. This works excellent in mine running 50%1 pre-mix with PENNZOIL synthetic blend oil. But I have some very mild porting done in the exhaust ports behind the sleeves, and my air box has been slightly ported as well and I have a .020 over bore. I still trhink there is a problem with your link and sync or in the timing department. These engines are CRITICAL of timing. 2 degrees to much and meltdown happens, 2 degrees not enough and your 140 is a 115. THEY HAVE TO BE DEAD ON! I learned this one the hard way
