Thread: 186 Engine problem NEED HELP

OK after a bunch of fiddling and farting around, I've got it running! yay! put on a new brake booster valve thingo and tuned up the rebuilt carbi! (i think i've got it right!)

BUT still having trouble with the vac advance line.... without it runs nice, with no show! So i've emailed the supplier to ask for advice. See what he comes up with. (hopefully I"m not just stupid)

On a different note... I'm going to the Mackay Home and leisure show that is on this weekend! going to go check out some stuff - try to get some cool ideas for camping setups etc.

no such thing as correct timing for holden 6-it all depends on the rest of the setup and fuel mixture.

most holdens don't use manifold vac for dist advance.
they use a port above the throttle or venturi vacume to increase timing at high speed cruise.

for pollution engines they swap to a 102 degree water temp port to increase timing at idle--to help cooling system.

most of these engines don't need vac advance-you adjust the mechanical advance that is retarded-as it uses vac at higher revs.

my cars I found the HQ 173 dist advance curve to be good and used manifold vac with airconditioning.

Thanks again for everyones help

Just found out that the supplier is going to call me today regarding my problems with install. He emailed me and said that he has never heard of anyone with these sorts of troubles....
