So as the title states we have been having problems with my 130 1989 2 stroke OB. So first I realised the left bank head wasnt getting hot at all, while the right bank was getting fairly worm/hot to the touch. I have swapped the coil and plugs from cyl 1 and 2 and still the same problem (ofc I had already changed the plugs for new ones before, change the fuel filter, had the carburators adjusted and so on). Anybody already had that happen to them?

as always check compression and spark on a motor to start out with.
find out what is good and what is not.
if all is well with that then chase fuel problems.
if no spark on certain plugs let us know which ones -
Compression has been tested and was within 10% of each other. Spark is in all cylinders but the left bank seems to be weaker because when I touched the plug, I could leave my hand on the left bank ones but not on the right banks.Comment

good compression and good spark on all cylinders means you get to chase fuel to air mixture.
too much fuel or too little fuelComment
