BTW, Swisher is much more experienced than I at this, so truth right there. ALSO.... reading forums hardly qualifies as research, too many know nothings that think they do, so DIS-infomation, like you cant use a DP with an auto trans, is much too prevalent. FakeBook is the worst at this, but we do live in the DIS-Information Age
, so alter "research" appropriately. Maybe its my age, but the level of bullchips is deafening these days, in all realms. ( I fear we are digressing into a nation of liars, cheaters and thieves)
Buy some Castle "Dragonfire" ( the only combustible carb spray left AFAIK
) , and blast those air bleeds FIRST. Then buy a "105" PV and throw it in the primary side. Holley using 065 stock is a "dumb it down" move, as most systems respond well to a bump in power valve opening on the primary side. ALSO, you can switch the font pump cam to the "winter" position to give it more shot earlier. Intuitively, I think the issue in in the cams. If I recall , blue and yellow cams are pretty early shots. I have a spec sheet at home I can post if you''d like, direct from Holley.
The Pump Cams "time" the shot, while the squirters time "duration" of the shot. What is weird is I use 25's on my tripower, as it has 3 squirters, but man , they be small. I suspect, your pump cam is off, meaning the timing of the shot is early or late. Remember the squirters only give it time delay, while the cams "time it".
PS, a vacuum gauge really helps dial in a Holley, esp with setting the power valve.
So this was a known good running Holley 650, or one in need of a rebuild?????
