Re: Newbie needs truck help
Dieseling is normally too high idle or a timing issue. On occasion, an electrical feed back when using electrical fans.
Cab mounts are easy to replace if you have a big enough floor jack. |

Re: Newbie needs truck help
GM used nylon gears on timing chains. When the nylon breaks, the timing chain is shot! It happend to my old 305. Timing chain failure finally did in the engine. I would start with checking the timing and tuning the carb. Use a vacuum gauge to tune it.

Re: Newbie needs truck help
I don't see a timing chain causing it, either the idle is too high or the timing is wrong, usually it's the idle.

Re: Newbie needs truck help
huh? speedo cable being broke caused it to die or you shut it off? how the crap can it sound like a battery dead? if it's running? Need to clear things up a little better please in order for us to help you.

Re: Newbie needs truck help
I noticed the speedo wasent workin so Im guessin the speedo cable is broken. I pulled the truck over and shut it down and when I went to start it was acting like the battery was dieing because the starter was crankin slow. but when we got back to the sellers place and shut the truck down and he went and started it and the starter wasent actin sluggish and cranked over right away. Is it a starter problem? I hope I clarified the problem because I really dont know how to describe it.

Re: Newbie needs truck help
Carbon buildup in the cylinders can also cause dieseling.

Re: Newbie needs truck help

Re: Newbie needs truck help
As for slow cranking of the starter that can be casued by having the dist. too far advanced.

Re: Newbie needs truck help
when any of mine have dieseled its always been the timeing for me. usually too advanced but I also retune my carbs anytime i change timing so could have been that too i guess.
