Chased down my carburetor adjustment problem
Weber 38 DGAS on 74 1.5F with headers and an HEI lightning strike.
Could NOT get this adjusted...
It was running rich... installed an adjustable fuel pressure regulator which i had not done upon install and set it to 2.5lbs.
I had jetted it for sea level when i arrived in Florida from Colorado, but when i checked the choke side idle, it was loose when set into screw. I pried the opening until it fit snugly.
Once i found that flaw, i could set timing and adjust idle mixture. It would not adjust before as it was dumping excess fuel on choke side idle.
My timing light died out, but i think i have it around 10• -12• advanced.
No ping, no run-on.
I installed new NGK plugs gapped at .040 for that distributor.
I'm still burning oil, but man she is running smooth and strong


.
I think my 7-9 lbs out of stock mechanical pump was overwhelming the float AND enough pressure to push out that choke side jet. Dumping fuel.
Now i could use some advice on how to mount that fuel pressure reg...
See pics
I "strapped" it out of the way with whatever i had on hand. I see that i could bolt a bracket of some kind into the manifold below the carb??? I could use a piece of old muffler hanger i have but i still need to fix the regulator to it somehow??? Without linking the hose, without dropping hose or fuel onto the exhaust...
