    Chrysler 1981 55HP Possible CD problem

    Joe you would see the timing mark at idle and should be about 3dgr BTDC at about 800-1000 rpm. Timing decal is for top cylinder and you can make an own mark for bottom cylinder. Should be 180 dgr from top cylinder.

    Chrysler 1981 55HP Possible CD problem

    Maybe there are some electronic components or one component in the trigger ring or in the CDI box that will fail while it is getting warm/hot. As you have spark at one coil I think you can exclude the stator. If the stator fail you would not have any spark at all. If you are a little handy and...

    Chrysler 1981 55HP Possible CD problem

    I suppose you have the Prestolite CDI ignition system with trigger ring, CD box and two ignition coils. First try to swap the coils and see if the issue follows the swap. If the #2 cylinder loose spark the issue is the ignition coil. If not check the connectors for the trigger signals, the...

    running rough at idle

    Are you going to replace both gaskets 8268711 and 826738? No extra liquid seal such as RTV are needed. I would put some spots of liquid seal at the gaskets just to hold them in place when you reinstall the parts/power head.

    running rough at idle

    These bolts for the exhaust cover are a PIA to remove. They are small 1/4 in and will snap very easy. Especially the bolts in the lower part of the cover, they are exposed to the hot exhaust and will stuck really hard to the power head. Looking at the exploding view there should be...

    Piston tool for Chrysler 75 hp 757HB

    Yes it is as racerone says with the Wiseco pistons. If you bore 020 over size just do that. The clearance is calculated, but you have to check the ring gap. That is what it is in the instruction for the Wiseco pistons.

    If you get exhaust in to the cowl the gasket under the power head to the leg may leak. It can also be the gaskets for the exhaust cover or both of them.

    If the ignition coil been replaced with one from a Roadrunner the system has been converted to a regular auto style system. You have a belt driven distributor system with points and condenser. The pre owner has removed the Motorola CD box and replaced it with a auto style coil and condenser...

    running rough at idle

    If the needle bearing is okey do not change it. You have to split the crank case to change the bearing cause the bearing has a locating pin in the crank case. If both pistons are clean the lower seal is not the culprit.

    running rough at idle

    Yes, if the stainless steel plate or some of the gaskets at the exhaust cover plate are leaking you will have water intrusion to the cylinders. If your clean piston/head is the bottom cylinder check the lower crank shaft seal too.

    Check out Ebay, some maybe show up. I have two of the Chrysler OEM tacometers, found them at a local advertising magazine, but that was about 10+ years ago. The Chrysler OEM gauges are rare.

    Piston tool for Chrysler 75 hp 757HB

    Has to correct myself. Piston pin has press fitting to the piston but not the spacers. The difficult when assemble the new piston with the needles/bearings and spacers is to assemble the spacers so they will rest to the bosses at the piston. That is why you need the tool T2900. You bring the...

    1989 chrysler force 50 hp 507X9B timing specs.

    As racerone says timing does not get out of adjustment. If you have change trigger ring it maybe need adjustment. The OEM spec is 28 dgr BTDC static timing (running the starter) and 32 dgr BTDC if you set it dynamic (setting it at WOT). I would suggest to set the dynamic timing at a bit retard...

    Sea King 9.2hp Motor will not start

    If it back fires it sounds like a shared flywheel key or have you switched the HT cables to the spark plugs? Maybe the HT cable for the top plugs is put at the number two cylinder plug. Also check the reed valves, broken reeds will end up with no fuel/air mixture will enter to the combustion...

    That is not a spot for a button. There should be a light bulb in that place. The 9,9 autoelectric yes all autoelectric models 9,2 9,9 12,9 and 20Hp was made for fishing and the light bulb should be an auxiliary in the dark to handle fishing equipment.

    1990 Force 90 Won't Crank -Binding

    My experience from these LU is that you have to be really sure you have gear oil all way up to the upper bearing. The two holes in the upper part has to weep out gear oil when filling it. Check out the OEM factory manual how to fill the LU with gear oil. As the upper bearing is a tapered roller...

    Force 85 not firing on cylinder 3

    The Force power your post from Frank A is right and there has to be two "ground" wires from the Prestolite CD boxes. The ground wire for the CD box has to be there cause you have to have a circuit for the ignition coils. The coils are grounded at the prime side with a black wire and the...
