Re: 351W Assistance plz....
I've currently got the ignition set to 6, I'll have to try 10... Also need to go spend about 10$ on a tach, since I'm doing the timing rpm's more or less by ear of what sounds right (with a timing light, of course, but should probably be sure it is 600-800rpm for sure)
I'm pretty sure the accel pump is working fine. No play; not at home though, so can't check on the fuel flow, but I'd lay money it's there.
I keep looking at other carbs and wonder if the carb is just too darn big for the fact that it's a stock engine. I would have hoped the fellows at Jegs would have steered me in the right direction, but they just sold me this carb without blinking.... I really don't want to sink another 200$ into a 600/650, but we'll see.
The oil pressure rises quickly off-idle, starting at 20 after warm up and ending up in the 40-60 range, depending on RPM, so I'm guessing if I throw a higher weight oil in it, the pressure will stay up (using 5w30 now, getting cold here in ohio!) I had a problem in a Z28 where the oil pressure was dropping, but it was leaking near the filter, and since I redid the intake and the valve covers, there's no oil on the ground now.
I was thinking of getting a better ignition system to see if that would help as well - maybe a higher-powered coil, and stepping up the gap on the plugs to .050.... Anything I can do to "tinker" with this and get it to stop the hesitation would be awesome, since all the work I've done so far has seemed to assist the crappy idle it's had in the past.
BTW, the advance is coming off of the master fuel bowl (the FRONT of the carb, right?). The passenger vacuum runs to a block off (used to be hooked up to the air cleaner pre-heater, but I don't have a hose) and the rear passenger vacuum off the carb goes to PCV. This is a correct set-up, right? When timing the engine, the advance jumps pretty good even at idle, so I'm not totally sure if I've got those two lines correct in the front/front passenger....
I'll have to dig the holley book up, but the last time I tried to read it, it went WAY over my head. Guess I'll need to find someone who knows carbs in and out, since I'm still a relative noob at it.
