    fins/stabilizers

    I have a 1971 55HP Chrysler. I saw at Walmart a set of fins you attach to the LU fins. Looks like airplane wings. It's purpose is to keep boat level of sort as you accelerate. Its is rated for 30-50 HP. Can I use this on my 55? Are these things even worth the trouble? I am also thinking since...

    idle setting

    I have a 1971 55HP Chrysler. Model 557HC serial 3188. I tried over and over to set idle. It is my understanding that it should be about 750 RPM. I can not get it below 1000 before the engine dies. Now that I am writing this I am thinking maybe my Tach is not accurate. Once I get near 1000, (if...

    I have a 1971 55HP Chrysler. I put a gas filter in the line between the fuel pump and the carb. Purolator F50153, per Frank. I can see air going into it. Engine runs rough. but think I have piston problems, also. One piston has acne. More I accelerate, more air goes in it. It has an old metal...

    Forward/neutral/reverse

    I have a 1971 55HP Chrysler. When I adjust the gear rods in LU. The best I can get is it will go in Forward and reverse with it reving. Thats what happens when adjusted centered. I can adjust it to go in forward smooth without acceleration but then it won't go in reverse. I can do the opposite...

    Compression

    I have a 1971 55HP chrysler. How do I check compression? How much is the tool? I understand there is something you screw in place of plug. Do you remove all plugs together? Is the engine running when you check compression?

    bulb in fuel line

    I have a 1971 55HP Chrysler. When I pump bulb in fuel line to start, after several pumps it gets semi-hard. If I were to give it another pump or continue to pump, it gets soft and it stays soft while pumping. After starting it is soft all the time no matter how much you pump it. (I am talking...

    Coil/felt pad

    I have a 1971 55HP chrysler. As you can read my other threads, I am dead. I just removed the flywheel and noticed one of the pads next to coil, that rub on cam is not touching, not even close. Could this cause an engine not to start?

    Head Gasket

    Just wondering. I have read in post that you can reuse a head gasket and on others you cannot. Lets say you had a perfectly fine head gasket. No leaks. Nothing wrong with it at all. For some reason you had to remove the head. Like the spark plug port was striped. Now you have to remove head and...
