readjusted the valves running much smoother now... thanks for all the input.... now time to do some adjustments on the carb.

ok ya haven't done much with the carb except fix some vacume lines and try and get the idle down to 650 only got to 750 rpm adjusting the idle screw with the limiter on it but i'm sure the carb needs quite a bit of adjusting as well. probly gonna try and rebuild it if i can find a carb kit. but i will readjust with the lobes in the 12 o'clock position thanks for the advise it will help alot. also did adjust timing but with the idle at 750 so will do some more on that as well thanks again for the helpful info i apprieciate it alot.

ok thanks for the info will readjust tomarrow. thanks again

the only aluminum tag i can find is under the hood on the drivers side. but cannot read most of it it does have a few numbers stamped on the bottom of the tag though. i'll try and get pictures of tags tomarrow forgot them today.

Just thought i'd get some insight from other users on how they do their valve adjustments on the L20b because ive been reading up on it and it seems there are several different methods of doing it. the folowing is what iv'e read so far on different web pages and such. 1. the way it states in the factory service manual it to bring the no.1 cylinder to TDC and adjust some of the valves then bring the no. 4 cylinder to TDC and adjust the remaining. 2. i read where a guy says the he puts the cam lobes in the 10 and 2 o'clock position the adjusts the valves for that cylinder then goes to the next one and does the same. 3. another guy states that the cam lobes should be straight up in the 12 o'clock position. then sdjust them. And on other old cars iv'e always brought every cylinder to TDC first. But they wer'nt overhead cam motors. So i'm a little bit confused i did it the way the factory service manual said but didnt have much luck. I'm thinking it could be that i may have adjusted them a bit to tight but i'm not sure i warmed up the engine before i started but it took me a minute being i haven't adjusted valves on an overhead cam before. But i'm getting a little hesitation on the throtle and a little bit of a missing type result. which i didnt have before i started. and need them adjusted because one of the rockers fell off from i believe was from slop from not being adjusted before maybe ever. any comments or insight would greatly appreiciated.

my wife cant have kids or it would definatly be a possiblity once its fixed up lol

i dont use armor all on anything after it cracked a dash on another one of my cars about a week after i put it on.

true, learned that the hard way but mothers is what it accually has on it in the pict

looking forward to it being a fun project . camper almost seems more used than the truck itself ,.anyways i'll keep you all updated with info and pictures as she progresses, my wife calls it my new dog house. lol ,also thanks in advance for any insight on getting it running in top shape cause thats where i'm starting first.

thanks one of the cleaner parts of it lol. not to mention i cleaned cab

Hope i did this right!! but if you can see theres lots of work to do to inside. My main concern is to get it running really good right now. Also adjusted the valves and must have got them a little to tight cause its running rougher than it was before. went by the factory service manual for a 78 620 i read on a thread somewhere that to adjust when the lobes are in the 2 and 10 o'clock position would that have been a better way. any ideas. other than go back in and adjust again.
