thunderbolt 150 Posted September 24, 2016 Hey I just changed a cam and really need this motor to start first go. I have an XD electronic dizzy.and wanna know if there's a way i can set it so the motor will run good enough to run the cam in. Thanx Share this post Link to post Share on other sites
CHESTNUTXE 7,259 Posted September 24, 2016 Just put roughly 10 -12 deg in at the balancer and fire her up Share this post Link to post Share on other sites
slydog 7,873 Posted September 24, 2016 What ever you set it @ you can and I still do set timing on cam run in anyway. Too retarded and it will hurt the engine and run very hot to advanced and it can cause detonation issues. Prime the oil pump and start it with rocker cover off and with a paint texta dot the backs of the pushrods so you can see if there spinning and if so slip the cover back on and do the rest of your check's and cam run in. If you don't check pushrods are turning you can wipe a lobe all but straight away. 1 Thom reacted to this Share this post Link to post Share on other sites
thunderbolt 150 Posted September 24, 2016 Getting that fire up without too much cranking over is always tricky. May have been ok but i could have flooded it when i filled the bowl on the holley. I sort it tomorrow. Share this post Link to post Share on other sites
CHESTNUTXE 7,259 Posted September 24, 2016 is it a 6 or 8 ? Share this post Link to post Share on other sites

CHESTNUTXE 7,259 Posted September 24, 2016 ahhhh i thought you had a cleveland,well principal is the same but maybe some 6cyl boys can chime in and give a starting point for timing. Share this post Link to post Share on other sites
thunderbolt 150 Posted September 24, 2016 6to 8 deg but is there a way to time it statically ? Share this post Link to post Share on other sites
gerg 10,871 Posted September 25, 2016 I used to set the timing on the balancer, remove coil lead from dizzy, plug it in to a spark plug and then turn on ignition. I then made sure the outside of the plug touched the engine and rotated the dizzy till I got a spark. I noted roughly the point of rotation that the spark occurred and set it there. This got me well into the ballpark but with electronic, it's hard to determine the exact trigger point that the pickup uses, unlike points which is either yes or no. I'd say with this method, you'll get within 5 degrees of correct timing. That's of course assuming you have the right cylinder firing. Share this post Link to post Share on other sites
thunderbolt 150 Posted September 25, 2016 Yeah just done that but used timming light and theres a mark on the dizzy where the trigger point seems to be . I think it will work. I'll just prime the oiling system again and try again. Thanx for the replys Share this post Link to post Share on other sites
Butcha 111 Posted September 25, 2016 I always put the balancer on 30deg adv drop the dizzy in make sure its point straight at #1 post n it fires up 99% time worry bout timing after the rest of the checks. Electronic distrib has a start and finish line on the black cover below rotor to help with install. Put the rotor on start and drop it in it will end up on the finish bolt er up n crank er. If im running a cam in i normally hookup a set of jumperleads to a second batt to save muckin around with timing. Faster crank faster start. Helps with spark too.

CHESTNUTXE 7,259 Posted September 25, 2016 Yeah i went thru all this a few months ago,after thom said rotate the dizzy 180 deg it fired instantly i had it on the wrong stroke Share this post Link to post Share on other sites
thunderbolt 150 Posted September 25, 2016 yeah i got it on the right stroke i rotated it and watched the valves. They dizzy wires might be up to shit tho. There's a pink/red and a black wire. pink one goes to coil negative right ? Black goes to coil positive. Seems wrong some how Share this post Link to post Share on other sites
CHESTNUTXE 7,259 Posted September 25, 2016 lol nooooooooooo the black is usualy the negative swap it around and it fire up Share this post Link to post Share on other sites
thunderbolt 150 Posted September 25, 2016 yeah i had that wrong the pink wire is red. got confused with xf est wiring Share this post Link to post Share on other sites
