gonna try to quit laughing at the joe dirt pic long enough to type....lmao!!

BJ, I need to do some investigating on my old distributor, I may be able to figure out somthing there with the vac....we'll see...

Thx zig & elbine, hopefully the weather forecast will hold true for this weekend, sunny 70, if so, friday I'll do some road testing & tuning around the 'hood, and try to get it to the exhaust shop, and time permitting to get an alignment....then I can get the tag next weekend....I'm also gonna try to get the console built, and paint a couple of the trim pieces too....kinda ambitious plans, so we'll see....

well think about it.u got 2 monstrous sidedrafts pulling all kinds of vac.i suspect ur hose size from the intake plenum to the dist hasnt changed right? even with a caM,etc, u havent changed the displacement of the mota have u? somethings got to give and I expect that would be vac to the dist.I would start there And work my way back.oh and be careful if u drive it as the brakes may be a bit slow as well.bj

Sounds good man! I love the deep tone to it. I finally got my DCOE idling properly. It took a larger idle jet and I now am tuning out the bugs with the main jets. Gotta love the process for the sheer fun of the end result! -Ed

Thx Josh & Ed! Glad you got your sidedraught tuned in, and yeah, getting them tuned right does offer a great deal of satisfaction!!

BJ, I am with ya, I would like to have a stock or near stock truck to check the vac on @ idle and up thru the rpm range sa in 500 rpm increments (if anyone has a vac gauge & near stock b2200, and cares to take some readings & post them up I would greatly appreciate it!), that would give me an idea if I'm in the ball park......
I also need to take a gander at my old dizzy, I'm getting old & can't remember if there is any mech advance weights & springs built into them or if it is just vac advance...if there is mech advance, it would take over after the vac advance falls off, so the vac issue may be as simple as only pulling reference from one runner instead of all four runners on the intake, or some combo of the such to get it in the right range close to stock @ idle, and as the vac advance falls off as you gain rpm's, the mech adv takes over....now if the dizzy doesn't have mech advance, I'll have to figure some way of correcting the high vac at idle falling off to no vac as the engine revs....I may be able to use the aux venturies from these carbs, they offer some vac at idle, and then as the rpms go up, so will the vac which would correct the issue....but no point in purchasing the aux venturies ($26 ea.) if the dizzy has both mech & vac advance....not to mention installing them on the ports that I have tapped into the carb flange on the intake would require removing the intake & carrying it back to the welder, plus putting them in would restrict the airflow somewhat....ah, the trials & tribulations of r&d & tuning....at least I've got something to tune on now instead of an empty engine bay, lol haha!!

I'll be sure to take it easy on the first road test.....I'm quite sure the brakes, clutch & throttle will take some getting used to.

or forget all that and go all electrical???BJ
nytrdr24   +1y
shewt BJ, that would get spensive....standalone, crank trigger, twm throttle bodies, fi fuel pump...assuming that is what you ment by all electrical....that is an easy 3k right there.....I'll stick with the ole skool, and use teh 3k for a paintjob & coilovers for the front!!

well,considering ur a man of means and such I thought u would just opt to go first class all the way.Lol.bj
nytrdr24   +1y
lol, hard to go 1st class when your broke....it would be sweet....i'd even consider running a turbo with the itb's & stand alone..but if I wanted that route, the 16v kia would be the ticket....
