Re: Jim Bob a build thread

might be tops 6-7000 kms on those

outa tune i suspect,with it being so screwed when I got it
vac advance was wrong spot,right since i got it
timing chain was done,fixed last winter
took out 305 plugs, last fall
dizzy weights were rusted tight,but loosened up better now

suspect the crud in the gas line ,
which i think is the oringinal 305 line and pump
has caused me some running probs ,and may have the PO setting it up too

i'd wana see the lighter colour brown on the tips ,more like the outside cyclinders
if you floored it 3 or 5 would miss fire sometimes, and blow back threw the valve cover
figured timing .....

lol but it did start faster this time
