I've posted a few times about trying to figure out why my SBC 400 was twisting off the starter bendix. since i put this motor togeather this has plagued me until recently. it's a stock motor w/ a 288 blazer cam, old edelbrock manifold, topped w/ a 1406 edelbrock carb. everything is swapmeet special stuff. down at the flea mkt. yesterday i got a $5.00 timing lite that i have been needing since the motor build. when i first got it goin i static timed it and then tweaked it till i got it to keep from breakin bendixes off. I timed it to 12' btdc and it runs like shit. had to raise the idle again, but this time she would backfire, surge and run 25 degrees hotter than before. i made sure that the harmonic balencer was on by bring #1 to tdc and the mark was on 0. so i figure that i must be runnin to lean and do a plug check and it's not runnin lean. should i try to get it to run right by the timing #s or bring the timing in to where it runs at 185 degrees all day long a up to maybe 200 when ideling in traffic? all's i know now is that it's been starting every time lately and haven't put a bendix in over a month.one thing i did notice is that when i started off and it was runnin good, the timing mark was above the degree scale and moved down, and in turn run worse.
