belac515 Posted April 21, 2011 Report Share Posted April 21, 2011 I have an 86' 720 and whenever I shut off the engine it shakes pretty hard for a second or two and then stops. I've been trying to find some solution to the problem for awhile now and i'm not having much luck. At first I thought it may be a broken motor mount, but they seem fine. Also someone else suggested to check the vacuum advance to the dizzy. I've heard of dieseling, but Im not too familiar with it. So could that possibly be the problem? If so, how would you go about fixing it? Quote Link to comment
flatcat19 Posted April 21, 2011 Report Share Posted April 21, 2011 Right as you turn off your key, let up on the clutch a little bit. That will put a little bit of strain on the engine, and help prevent the dieseling-if that's what you're having. Now make an intro thread-and lets see this truck in question. Quote Link to comment
ariascarlos1990 Posted April 21, 2011 Report Share Posted April 21, 2011 Whats your timing at? Do you have an after market carburetor on it? Quote Link to comment
izzo Posted April 21, 2011 Report Share Posted April 21, 2011 Its dieseling. Theres things to fix this, letting up on the clutch will not fix it... Check timing, check plugs, check tuning on carb etc. What carb is on it? Quote Link to comment
belac515 Posted April 21, 2011 Author Report Share Posted April 21, 2011 The engine and carb are all stock, with 170k. I bought it about two months and the owner said the carb had been rebuilt within the last year, but I'm not sure if it really had been. Also, this is probably a major newb question, but where do I post an introduction? Every forum I've been on has an area just for that and I haven't found one here. Quote Link to comment
izzo Posted April 21, 2011 Report Share Posted April 21, 2011 probably best to do it in the project section maybe that way you can just keep updating it with your progress. Quote Link to comment
belac515 Posted April 22, 2011 Author Report Share Posted April 22, 2011 Thanks for the help guys. This weekend I'll do a good tuneup with new wires, plugs, cap, rotor, fuel filter, ect and check the timing and carb. Also here's my intro: http://community.ratsun.net/topic/31013-calebs-86-720/ Quote Link to comment
izzo Posted April 22, 2011 Report Share Posted April 22, 2011 id double check timing and stuff before throwing money at it, but thats just me Quote Link to comment
belac515 Posted April 22, 2011 Author Report Share Posted April 22, 2011 I definitely will, but It still could use a good tune up. I haven't done once since I got it, and i dont know the last time the previous owner did it, if he ever did, so it couldn't hurt. Quote Link to comment
