Still Bogging
engine runs pretty good, all except the moment i get the clutch all the way and it bogs. its not a major bog, but its just enough that i cant really scoot (or burn) from a stop. the revs drop just enough to wear it is noticeable and quite annoying if i want to get on it. the accelerator pump squirts instantly. infact just a wiggle of the throttle arm makes the pump start shooting. its very sensitive. i timed as per the recommendations of the experts of the forum here. this weekend i tried twisting the distrib just a bit more to see if that would help and it didnt. infact i started pinging a little, so im gonna have to twist it back. any other ideas for what to look for to solve this bog problem?
its a low horse 327 with a holley 650 ontop. dont know much about the carb. i havent checked floats yet. probably should do that next?

Bring it by and we'll take a look at the carb and check your timing. I watched Lars do a couple of these the other day (including mine).
I'm in Santa Ana so it's about an hour's drive (without traffic).

that is quite tempting, but thats over twice as far as the furthest ive driven the car. not sure i trust it that far. plus, id like to be able to do some of these little tunings on my own.

Is it a Bog or possibly it's Lugging? Do you know for sure which rear end and transmission you have? If you couple an M21 with a 3:36 it might feel like a Bog! Does it feel this way when passing or accellerating once you are going?

it could be lugging. i dont know what rear and trans i have. the one thing ive noticed about the trans is that when shifting into 4th the rpms drop significantly, much more noticeable drop then the 1-2 and 2-3 shift. once im at speed acceleration seems fine. the car isnt fast, but it seems quick enough at speed. its just that little hesitation or whatever it is the minute the clutch comes all the way out.
