1972 318 chrysler industial

i have a 318 chrysler industrial engine in a wood chipper. problem with it is when i hook up the vacuum advance line to the distributor it will stall the engine after a few seconds almost like it is advancing way too much. has anyone ever ran across this problem. i've been working on engines for 50 years and have never run across this. the manual says to set the timing @5 degrees BTDC. does this sound right. thanks for any help.
 
does the distributor advance work on ported or manifold vacuum? you may be hooking it up to a manifold vacuum source when it should be a ported source.

hook a timing light up and watch the timming mark as you suck on the vacuum advance line.... does it retard or advance the timeing? many carburators have both ported and manifold nipples on them to hook up vacuum lines. you may have hooked it up to the wrong source.
 
some industrial engines don't have a vaccuum advance as they were intended to run at one governed speed and do not need any more than the centrifuigual advance. next question what prompted this is this engine new to you or was there symptoms which caused you to pull the distributor. chryslers in the late 70 ' and 80's had a weak plastic cam gear which caused early timing chain wear maybe that that is the root of your problem also don't rule out chafed wires on the advance plate. and you can't put in a mopar distributor 1 tooth off unless yoy pull the oil pump on chrysler motors they have a keyed shaft like a vw
 
thank everyone for their reply to my problem. the chipper is new to me and i was tuning it up and had noticed the vacuum line off of the distributor. i had hooked it back up when i had noticed the problem. to my knowledge the distributor hadn't been taken out of the engine so it leads me to believe the problem has been there for quite a while. i will check for a chaffed wire in the distributor. if thats not the problem i will probably just leave it be. it seems to run fine with the advance unhooked. one reply had said it runs at governed speed all the time so it should be fine the way it is. also does 5 degrees BTDC sound right for this engine. just making sure of the timing. thanks again for all of your help guys.

don thank you and everyone else for your replies. i found the trouble this am.something that i should have checked i didn't and that was the point gap. (my ignorance) they were wide . about .022/.023 . only thing i can figure is when it was fully advanced it was just too much of a gap and made it cut out. i ran it for a couple of hours today and ran great. thanks again for everyones help. this is a great site. jim

points what year is this? chrysler stopped using points in 1972

yeah it's got points don and its listed as a 1972 wayne chipper with a 318 chrysler industial unless somewhere down the line the year got messed up. i'll double check though.
 
Industrial engines were made in longer runs so a carb/points engine might have been installed new for a few years after the car/truck engines changed.
My 1972 Muskeg with the 318 industrial also has a carb and points.
 
the carbs were used right up to the late 80's but chrysler started points in 71 or 72 a few years ago i found a 330 hemmi industrial with dual point ignition attached to a pump
 
A lot of the 318 industrials for sweepers. chippers, farm combines etc had governors mounted right on the distributors.
