I have a 1972 55hp Chrysler outboard model #557HD. Where can I find parts for this motor? I'm looking for coils and possibly a carb rebuild kit. Thanks!
Stupid question.. but have you changed the plug? Make sure you are using a number 8 plug ie: NGK BR8EV etc. Whip the cover off engine and just check there is no moisture in there.. My 380 EXC had all the same issues as listed and it had water in the cover. If it has compression, then the head...
I run a YZ250 at 40:1 and 33:1.
Talk to your local dealer. Ask spare parts to ask the mechanic, spare parts can give real bad info somtimes. Remember to tell the mechanic if the needle has been changed etc.. Carby changes make real big differences
