i got a 1641 w/ engle 100 cam, just bought a weber 40 idf carb for it, installing tonite, but last time out i was having problems and stuck like chuck and drunk so i started messin with the distributor tryin to get it to crank better! think i was hydro locked cuz of the junk solex carb but anyhow, puttin new carb on it with a fuel pressure regulator. what should i set the regulator at? im thinkin 2 psi but would like some input. also at what degree should my timing be set at when i get all together and running, thanks in advance for any info and help! tryin to get this thing runnin for the hillclimb at harlan!!!!!!!!! see you all there |

Are you running a stock pump or electric? If stock you don't need a regulator.That carb only needs about 2-3 psi.Set the timing at 30 degrees at 3000 rpm.Run 93 octane gas. |

Curious why you would run 93 Octane in a 1641 motor. Is the compression above 8.5:1? Regular gas actually burns hotter and will produce more power than a higher octane that is formulated for higher compression motors. |
