Motor timing 180* out?

    Hi gang,
    After struggling with a no start issue this summer and finding a sunken float in the carb. it seems I have larger issues. Without disturbing the distributor (I don't care for the term 'dizzy') it seems the Inital Timing is about 180* out. (A lift of the lynch lid to Jeep Hammer for suggesting this) After detirmining this I pulled the distributor and checking the distributor gear it looked almost new.
    In the past I've had a '69 Pontiac LeMans that fell out of time and it was the 'silent runner' plastic timing gear that had stripped and was evident by the erratic revolving of the distributor rotor. Since AMC uses steel gears and chain how could the IT slip to this degree? Or am I missing something here?

    Thanks in advance for any help

    its easy enough to go TDC I would start over from square 1

    also might want to check rotor.. if the plastic tang isn't seated in the distrib properly the 180 deg out could be under the cap, not in the engine.. (has happened to me before)

    Thanks for the responses guys, the Blue Streak rotor has a tab on it's insides so one can orient it correctly. The motor is an AMC 360. I'm tearing into it again tonight with a friend. What with my limited time for wrenching owing to my 7 days working week it's not easy.

    As if I didn't have enoungh to contend with it looks like the starter went tits up too. My best friend (just out of back surgery) has been helping me with this latter process. We recorrected the distributor position as we had moved the oil pump shaft slightly. The starter was a pecker to remove what with the header and bulkhead right in the way of the upper bolt. My buddy's taking it to the parts shop today for testing/replacement, but the way it looks this morning I'm too tired and sore (torn left bicep) to have at it again tonight.

    My friend took the starter to the parts shop for testing for me, on the bench it was growling, seemed to have a bent shaft and was doing 40 amps - the clerk said between 30-120 is okay, but he got me a new lifetime one anyway

    Is it the factory distributor or an aftermarket HEI?

    It's the Ford version EEC 1 that came stock on the '78. Took the primary battery in for testing and getting some more welding cable for connections later today.

    After removing the newly charged primary battery and taking it to NAPA for testing the results were 600 out of 800 CCA. They said they'd put it on their charger this morning and re-test it.

    Well I stopped by NAPA on my way home last night they said they wanted to keep the battery for another day and re test it again, kind of odd that.

    They likely forgot to put it on the charger, or left it connected to an unplugged charger and it's flat, or something similar.

    I brought a fully charged Napa battery to my local Napa store and they tested it with their load tester. Should not be a big deal. Suggest you let them keep it another day, take it back and take it to different store for testing. Do you have a charger? I would charge it completely before I took it in.

    Thanks timgr! It turns out the "battery won't take a charge" according to them. So, I've got to pay the pro-rate of $72.00 for the warranty of this battery that was used 25 out of 84 months. I think I'm going to go with a new Interstate battery for the same cost and longer warranty.

    Well I cleaned up the rotor, reinstalled the cleaned up spark plugs (along with some new ones that I exchanged for ones that didn't thread easily) connected the plug wires and fired it up. I got it to run for about 3 minutes holding the throttle open, in the hopes of warming it up to set the timing. My friend came over and verified my work and it wouldn't start thereafter. He capped the bowl vent and giving it another go we found fuel leaking from the carb. I suspect it's on account of that capped bowl vent. Going to uncap it tonight and open the air bleed screws a little more and try it again.

    Got it running in the same way last night and despite the bowl vent now unplugged this venerable AFB 'Black Stallion' seems to be leaking from both the primary and secondary shafts.

    Since fuel was seeping from both of the primary and secondary shafts I found a carburator rebuild shop up in Washington that I'm going to ship the throttle body to for bushing installation

    Throttle body bushing wear causes a vacuum leak and should not have fuel coming out around the shafts unless there is other carb problems. Don't be surprised after repair that you still have the over fuel problem. The idle adjust screws should be 1-1/2 to 1-3/4 out for initial start.

    WOW! The postman stopped by and he had this on his truck on Saturday! I had only sent this throttle body on Thursday! The throttle shafts are tight now and I don't think they'll be giving me any more issues. I'm going to put Carbs Unlimited on my resouce list, these guys are GREAT! http://www.carburetion.com/


    Since the recent rebuild all the gaskets are in good shape, but I'm flirting with buying new.
