Subject: 72 350 bogging when giveing it throttle around 3k
so i just got this bike last week and have only been around the block a few times(no permit) and when i give it gas it bogs then shuts off. and then i can't get it started. it seems it's getting too much gas. i blew out the filters, but no go. i don't have a manual so i don't know what's up w/ the spark advance and point setup. anyone know what my problem could be?

If the bike had been sitting a while, my first guess would be a gummed-up carb. A first quick check would be to try opening up the throttle on each carb individually (probably easiest if the bike is up on the center stand; gently lift each of the throttle linkages). If it revs with one carb more than it does with the other, you've confirmed the problem.

well i thought it might have something to do w/ the timing or points, so i first pulled the plugs and the right plug was way black and must be running really rich compared to the other cylinder. i'm gonna look for a manual so i can figure out how to set the points and the timing. it hadn't been sitting, the guy i bought it from used it daily. just not sure why the one plug was super fouled?

have a look at the spark plug caps,they have a 5kohm resistance built in ,as they age it can go sky high (ive seen 290kohm !)that will give a sooty plug ,it cant burn correctly.they unscrew off the wire,new ones are 5 bucks ,just replace them and go over the points before you tamper with the carbs,

Clymer (might be spelled Cylmer) makes a manual for your bike. They are alright but not the best someone else posted about finding reprints of original honda manuals. I would try to get original first but if you cant find one you can get the Clymer on ebay for around $20 at bike shops they run $35.
