I have just finished installing a new rebuilt long block 403 into my coach; rebuilt Patterson carb, new fuel pump, distributor cap and wires, etc. Got it up and running, no obvious leaks yet, good oil pressure, steady idle, timed to 12 degrees BTDC.
The issue I am having is that it is low on power under load. Going up hills will lead to slowing down or stalling the engine if more throttle is applied.
I'm guessing a vacuum leak or potentially my distributor vacuum advance has gone wonky but any advice of where you would look first is welcome.
Thank you in advance
