Technical > Spud Miller's Cave
Beginner, novice trying to run a BBC with Hilborn injection
msundstrom:
Is distributor timing on, lots of fire out the zoomies is a tooth retarded timing? BV leakage%?
tcoupekyle:
I have timing set at 36 degrees. IDK about barrel valve leakdown.
msundstrom:
Don't know your details that Paul brought up but mine for straight methanol was 28% +\-BV leak, 130+\- main jet with 2 psi idle bypass on a 6.08 gpm pump at 4000 rpm, throttle plates at .003 Hilborn 2 7/16" on a 467 inch BBC.
tcoupekyle:
Mines a 468 .090 pill aside from that I don't know if seems like it's giving it way too much fuel.
msundstrom:
Best advice I can give is send your pump, injectors and bypasses to Spud at Fuel Injection Enterprises and have it flowed and the tuneup will be very accurate, no guessing and no broken parts and it's very inexpensive.
