This article is exactly what i needed to read tonight! Lots of good info for a beginner weber user.

So i finnally got a chance to do my valve lash, set it while hot to .013. Before i go farther, timing is set and advances fine with throttle. Did a carb rebuild on my weber 32/36 dgev, my jetting seemed screwed up, fuel jets were both 35's, air jets were 170 primary, 120 seconday, main idle jet was 55 an secondary 50. Ive order a jetting kit. Im at 2400ft of elevation. So when i was setting valve lash i noticed 5-6 of my head bolts were not tight, so i went to tighten them but their stripped, not the bolt itself, but whatever their mounting into, they bite a lil bit but never fully tighten down, def not to 60lbs. How screwed am i? Also, i still have no top end, an am missing a bunch of acceleration. The engine is quieter which is good.

Oh an the choke plates are verticle as should be

Well i have spark from both coils, all my spark lines seem to be fine, ran a compression test from cylinder 1 to 4: 137, 140, 137, 125( tested each cylinder 3 times to give myself an average). Guessing cylinder 4 was cooled off more by the time i got to testing it, or its a lil more worn then the rest. I removed the catalytic converter, no noticeable change, de-smogged it as well. Same result of no change. Im going to get a carb rebuild kit, noticed a lil wetness comeing from a seal. I bought it from a feller who barely spoke english, he used it as a farm truck, so i have no clue if he drove it up from cali or maybe down from denver.. i wonder if the carb is jetted totally wrong for the altitude im at.

Hi all, I picked up an 85 nissan 720 4wd kingcab last week, it was barely running. Ive changed oil an filter, new spark plugs (ngk of course), fixed a leak in the carb fuel line, tightened down the valve cover (it was super loose), re done all my vaccum lines, most were missing, threw on a new distributor cap and rotor, set my timing via the sticker under the hood. Im idling fine (800-900), BUT, im still lacking a bunch of power an she just wont get above 50-55mph...whats going on? Could it be the vaccum advance? Any help would be appreciated for a new 720 enthusiast
