Jetting for a 9.5 to 1 Olds 350 with a 204/214 cam

[olds350]

I have Holley reman carb that has always ran nice and smooth. I know remans can be bad, this ones drives nice, always has. I recently bumped the compression from 7.8 to 1 to 9.5 to 1. These heads have porting, bigger valves, crossover's filled etc. Sanderson shorty headers, duals, 2300 flash stall converter and 3.42 gears. I currently have 71 primary jets with 44K rods with your blue primary spring and CV secondary rods, G hanger and the air door notched with it adjusted to 1.3" open. I had your book which destroyed in a flood this summer and buy my parts from you. I currently have the APT notched with a removeable plug to adjust it. I noticed the my car needed it adjusted 10.5 to 11 turns out. I needed similar with a stock 403 carb. I currently have it in the max rich position. Timing should be good. I was planning on going up a jet size to 72, sound good?

Well I swapped jets and it still ran like shoot. I checked my timing, so how something got messed up in this distributor, was set at 21 base timing. It was somehow at 43 base and wouldn't run below 40 base timing. I put in my Mallory 42 series distributor and set the base timing at 19 and 38 total all in around 2500. I have the vacuum advance set at 11 degrees. I reset the APT starting at 5 turns out. Stumbled bad, every turn up got better, around 11 turns up now and running much better. Are the 44 rods that Cliff's sells on his site for  M4M series carb, the same as the 44K rods?

 I noticed a stumble that nearly caused a stall. I found a cracked hose in two spots on the secondary pull off. Helped a bit, nice clean pull then a slight stumble again. The APT is adjusted all the way up again. 72 primary and 44K rods with Cliff's stiffest dark blue power piston spring. I pull 18" at idle. Pump arm is on the inner hole and has a good shot. This it at lighter throttle. My timing is now 19 base and 38 total in by 2500 rpm. I am running 12 vacuum advance, right at idle. I am getting annoyed by how this runs.

how does it run on the top end ?is the problem only on the bottom?just thinking out loud . if you have the apt screwed out that far you'd think that you'd be running on almost all jet .you didn't get some garbage in your filter when you had the engine apart? thats why i asked how it runs on top.fwiw

I am thinking it is accelerator pump. It stalled yesterday. I noticed it doesn't start moving fuel right away, not much anyway. It has the garbage Edelbrock pump, Cliff doesn't like them. I am swapping it out this weekend. I have a sag mid throttle, could be the APT setting.

What is the carburetor number, and hopefully you put one of our kits in it?.....Cliff
