    I drove my truck to school this morning and noticed the brakes were quite spongy until about 75% pressure then they started to kick in. dangerous, I know and I want to get it fixed asap. Is it just air in the hydraulic lines? or is something else wrong?

    So i ended up adjusting the idle, about a quarter turn for the choke idle and about a turn and a half for idle. Sounds better idling and doesn't die after revs. I took it around for a quick drive last night and she didn't stall once. it is a little faster when idling in gear but figures if you...

    do i simply just need to adjust fuel/air mix, or specifically idle mixture? kinda like a smaller carb on something like a chainsaw or ATV?

    Alright, i did some research and im pretty darn sure my vacuum lines all have vacuum, and are run to the correct places. i did however discover that the truck only stalls after high rpms. it runs just fine when i havent given any decent gas other than starting, but when i have a prolonged rev...

    haven't touched it yet, all ive done for ignition was new cables and plugs. I've double and triple-checked to make sure the firing order is correct. but I do feel like the engine has always idled relatively rough and could definitely be running better.

    Would the timing have anything to do with the idle? i know when I add throttle just a bit it smooths out so that's why I thought it was the carb, but could it simply be timing?

    i have done all fluid changes and filter changes, including a coolant flush. oil got pretty dirty fast but I just added a couple of quarts because it was concerningly low. the expansion tank is what I noticed, it was pretty much empty even though I added more coolant to the proper level and such...

    most certainly, the first drive home was over an hour, and when it was running better I've driven decently far, or for at least a while.

    Alright so i re-did my firing order and now my truck runs again. BUT At idle it sounds really bad and will just die if I don't give any gas. (I don't know the correct term but is controlled by choke) but the main flap(?), like the big one, wont open no matter what unless I manually open it. and...

    I 100% understand what you're saying and I agree, I do in fact do a lot of my own research though it may not seem like it. I just prefer to be able to ask real people specific questions about things I may be having a hard time understanding or really just could find beneficial information for. i...
