None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Yes I did remove the oil pump and I always had it at 5° btdc it's just that 5° used to be in the middle and now it's at the far end.... oh I see the confusion when I say the adjustment range here. I'm not talking about on the fly wheel. That stays on the same mark. But at a certain point without adjusting the timing (maybe around the time or shortly after I had the oil pump out, is possible) the timing changed and was way off and so I put it back to 5° except now the distributor has to be turned as far as it will go clockwise to be at 5° the slotted adjustment on the distributor is the adjustment range I'm referring to Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 5° used to be right around here and now as you can see it's all the way at the end there Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 I'm pretty sure the oil pump went back in just fine though I followed your instructions to the letter. I was trying to find that in my history but it may be on my other profile. I have two profiles because I forgot the login for the first one and made a second one Quote Link to comment
datzenmike Posted February 22, 2023 Report Share Posted February 22, 2023 Must be off a tooth. As long as you can set 50 it doesn't matter. Change the drive spindle one tooth this summer. Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 @datzenmikeok I guess I have to eat crow. I checked spark in the number one cylinder at first start this morning intake side does get spark exhaust side did not spark Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 So what does that mean? Because I'm pretty sure based on the rpms rising when I depress the clutch that the exhaust side plugs do function at least some of the time... I have a brand new ignition coil around here somewhere I could swap that if it's just a bad coil but that doesn't make sense to me Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Still in the box and bubble wrap. Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Little side question. When I tested the intake side and it was sparking I had a hold of it by the rubber boot and it was giving me a little jolt in the hand even through my dinosaur punching gloves which I thought were insulated against electrical shock... is that normal? Quote Link to comment
datzenmike Posted February 22, 2023 Report Share Posted February 22, 2023 That's good news as there is a function that shuts off the exhaust side plugs and that can be turned off. Notice the three wires with round lugs on the ends?? See farther back there is a plug with a white or gray wire? Unplug this wire on your distributor and hopefully the tach will work full time. No you shouldn't get a shock touching the ignition wires but it is possible. Don't change anything or you are adding more possible faults. If we get the ignition working there's no sense. Anything not working has to be proven non working first. Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Ok got it. I'll unplug that plug, we've done this before in relation to a different problem but I ended up hooking it back up I wanted to clean the spark plug end a bit and a spot on the block first just to be absolutely sure there is no spark and this isn't the result of bad contact but woman already took the kids to school so no helpers 😞 Quote Link to comment
datzenmike Posted February 22, 2023 Report Share Posted February 22, 2023 There is a function that turns off the exhaust side plugs (but could be the intake side if the two coil wires accidentally get swapped) This should only happen in higher gears and at full throttle so something is amiss here but unplugging that wire defeats this and both coil fire all the time.

None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Ok I did manage to double check it, still no spark. Unplugged the plug as Instructed and boom spark. So now what does that mean? Quote Link to comment
datzenmike Posted February 22, 2023 Report Share Posted February 22, 2023 Well does the tach work all the time now? That's all we need to fix for now. Engine will run better with all plugs firing. Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Idling just after starting. Still reading off Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 The crazy thing to me is that the tach does respond to changes in rpm I think it's just reading low a few hundred rpms. I don't know how a tach really takes its reading and outputs it on the Gauge so I don't know if that's even a possibility Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 It got there faster this time but it's still speeding up. The rpms are audibly rising slowly as it warms at 900 now since taking this picture Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Seems to have settled I turned the idle set screw back a bit to get it back to 700 I'm going to put the timing light on it just to see Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Still dead on the second mark from the right Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Found another issue, throttle is sticking occasionally I backed the idle set screw to lower rpms and try the mix again and it stayed the same until I pushed down on the throttle lever on back of carb 😞 Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Also idle mix screw all the way in still sees to yield virtually no change Quote Link to comment

Find this on the engine side of the carburetor... Take the rubber plug out of the center and turn the screw inside counter clockwise one or two turns, keep track so you can put it back later if this does not help. Did you ever try turning the BCDD counter clockwise? This can mess with the return to idle if set too sensitive. Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Could it have anything to do with how I've got those vac lines capped on each other ?? Quote Link to comment

If so then no Edited February 22, 2023 by None_zero Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 Do you want me to do that now? Also I'm getting no change from idle mixture screw. Or I should say no normal change it idles the highest turned clockwise all the way in until it stops. And backing it out there is a noticeable slow down about every full turn Quote Link to comment
None_zero Posted February 22, 2023 Author Report Share Posted February 22, 2023 (edited) So after getting the highest idle (even though it's with the screw all the way in) and setting the rpms I double checked the timing. And it was a tad low so I went to adjust it and the timing light looks like Morse code. It's not a steady continuous flash. Just thought that might bear mentioning and when I cut engine off it dieseled for nearly a full minute and then shot a puff of smoke/vapor out of the top of the carb Edited February 22, 2023 by None_zero Quote Link to comment
