Gheko 0 Posted September 5, 2019 Hi guys, looking for a bit of help, Mk3 cortina 1600 pinto, fitted with Sierra electronic dizzy bought off one, of ye guys, I can’t seem to get it running properly as it’s spitting and backfiring up the carb. Timing set at around 8 degrees btdc, take it any further and it won’t turn over hardly, take it back the other way and it’ll turn over but won’t start. Any help appreciated as I’ve spent way too much time at this. Quote Share this post Link to post Share on other sites
John Mack 246 Posted September 5, 2019 Are you 110% sure the firing order is right? Quote Share this post Link to post Share on other sites
Gheko 0 Posted September 5, 2019 Hi john yea firing order spot on, it’s driving reasonably ok but when you floor it it spits and backfire up through carb. Has me baffled 😕 Quote Share this post Link to post Share on other sites
dgo 66 Posted September 5, 2019 Do you have the old dizzy? If so does it run OK with that fitted? Quote Share this post Link to post Share on other sites
sheffieldcortinacentre 529 Posted September 5, 2019 Have you replaced the ballast wire with a normal piece & swapped the coil to a non ballasted 12v one? 1 Quote Share this post Link to post Share on other sites
Gheko 0 Posted September 6, 2019 Yep done all that, didn’t refit old dizzy, might try that, only didn’t want to have to go to all that trouble again. Anything else I could try before I rip it all out again 🙈🙈 Quote Share this post Link to post Share on other sites
sheffieldcortinacentre 529 Posted September 6, 2019 Nope but sounds like timeing. Is the vacumn advance working? Quote Share this post Link to post Share on other sites
Gheko 0 Posted September 6, 2019 yes my thinking aswell, but ive been over the timing several times and all seems good, how would i check exactly that the vacum advance is working? could it be an issue with thr carb itself ?😫🙄 Quote Share this post Link to post Share on other sites

sheffieldcortinacentre 529 Posted September 7, 2019 You should have a basic message as it still refuses to let me send a detailed answer I feel a 2lb tuneup coming on. Quote Share this post Link to post Share on other sites
