Firing order?????

Every thousandth of an inch smaller in the point gap advances the timing 1 deg, every thousandth wider retards the timing 1 deg. Dwell is the number of degrees the points are closed to allow the primary coil to charge.

Re: Firing order?????

Got it all wired properly and running again, I hooked it up to a hose on my hose port right before the impeller, For the amount of water that was being put into the engine, I didnt see that same amount coming out at all, It was still getting hot too and quickly, Im now thinking I have a blockage somewhere. Im going to set the timing tomorrow and grab my compressor and start checking for blocked coolant lines. ANyone know what my timing should be set at at TDC? I cant find it in the manual..

Re: Firing order?????

Everything was wrong on the electrical portion, Honestly have no idea how it ran properly....at all actually lol. Im glad its all wired right now, Also the gap on my plugs was way off, so I re gapped those.. and am hoping to get it all done and squared away asap!

Re: Firing order?????

Timing is 6 deg BTDC, dwell is 62-65. Set the dwell first.

Re: Firing order?????

I already set the dwell, It is at about 60-62, with a digital timing light, I just have to set the light to 6 and when its flashing I should see 0 on the crank pulley correct?

Re: Firing order?????

Is it possible for my exhaust manifold to be on wrong? The cooling system in the manual shows my exhaust exiting the rear of the engine, Mine however exits from the front, Out of curiousity I went onto google images to check out other AQ130C engines and came up with one

Its exiting the rear... Mine also has this stupid galvanized elbow someone made to adapt to the exhaust to make it reach to the rear.... Could it be on wrong? Causing blockage?

I'm not sure how to use those lights.

Are you saying you checked the dwell with your timing light?

Some of the early volvo's had the front exit manifolds. Someone may have changed it. Hard to say. Only way to tell if its plugged is to open it up. Have you tried draining the manifold?

Re: Firing order?????

I have opened up a few portions of the cooling system and everywhere has water in it. Also the flow is much better today than yesterday, maybe I didnt run it long enough? I dunno, However still getting hot. My manual says my temp sending unit is right near the thermo housing, which would make sense, However mine is at the rear of the engine on the head... Is that wrong? am I maybe getting a wrong reading? I am going to take it to wash it and vaccuum it out tomorrow, And am contemplating taking it to a shop, now I know all the electrical is good, I am no longer overly concerned at this point with cost of someone else to spend the time, I have spent a bit of time on it myself at this point and Im certain it if I realllllllly wanted to tear fully into it I could fix it myself, but I am so annoyed with it at this point I want to give it to someone else to mess with from here on in... What is everyones thoughts?

Re: Firing order?????

Oh and no I checked the dwell with a dwell meter, and as far as timing someone told me 12 btdc but someone told me 6 btdc here, so I listened to you guys and went with 6btdc. It seems to run well, starts right up everytime, Almost sounds like valves need adjusting. But anyway, We'll see I guess

Re: Firing order?????

To make sure the temp is reading ok, get yourself a cheap infrared thermometer and point it at the base of the temp sender. It should read the same temp as the gauge. I feel ya on the frustration factor. If spending a little money to pay a mechanic eases your mind then go for it. I would encourage you to go through the basics however, It's not that complicated.

beginning at the outdrive. The intake fitting on the top of the intermediate housing is a classic corrosion problem. Pull the "s" hose off and check its condition. Next comes the impeller, the thermostat, The oil cooler, and the exhaust manifold. Back flush whatever you can to try to find blockage. When I first got my boat, the exhaust manifold had a bunch of sand in it. Does it overheat under all conditions, or just at certain times?

Anyway, glad you got it running well. You can always adjust the valve later if you want, can't hurt.


BTW, 12 deg BTDC Is correct. I rechecked. Sorry to have misinformed.

Re: Firing order?????

Lol, Alright, Ill reset the timing lol. Ah well no biggie. I agree, and the master tech at the shop next to the one I work at said today he'll help me for an hour for free which is awesome cuz he is basically a genius, and I really just need someone with fresh eyes to look at it, instead of me just looking at the same things again and again lol.

It starts everytime now which is awesome and all my gauges and lights work properly now. Got rid of a bunch of wires that were added and going to random places. SO thats good.

And it does overheat at anypoint, revving or at idle, and rather quickly. I was already thinking about getting the infra red thermometer, so Thank you for reassuring me on it. So maybe today if not the next Il have some more insight and maybe fix the problem Does anyone know if I NEED a thermostat or if it can run at normal if not cooler operating temperatures? I DO NOT have a thermostat and need to know if its a must and if it is, Ill get one before that tech checks it out so he can have an accurate analysis..

Re: Firing order?????

I would definitely put in a thermostat.

With these marine engines, it's all about the flow. If the flow is restricted, it'll overheat, If its plugged or sucking air on the intake side, it'll overheat.

Let us know how it goes.

Re: Firing order?????

All bad, Had my buddy at the shop next to mine take a look at it, and seems as though the guy who built the motor built it from a few misc motors, I have a different head, and my thermo housing is modified and the reason its getting hot is because where th water comes in it exits immediately, Yes I have great flow, However its a direct flow to the exhaust, bypasses the block and rests in the head, so I have to modify the thermo housing to accept like a heater hose of some sort, and take this plug outta the rear of my block and put a fitting on that and basically tie them together and force water through the block, Gonna be a custom mod, lol, If you want to call it that. But I hope it works.
