Hello everyone, second time ive been looking for help since owning the boat for just over a week...
While out on the boat i notice it was getting really rough and kept stalling at low revs and as time went on it got worse.
Once out the water i pulled the plugs and notice the top cylinder (2 cylinder, single carb 40 model) was very wet.
The engine would start ok but run rough and would do a big missfire every 30 odd seconds followed by blue smoke. what was strange tho, if i added a bit of choke it would stop the big missfire but was still very rough.
So i started it with only the top plug and it was very lumpy but with the bottom plug only it was very smooth. in some ways better than with both.
So the fun begins;
replaced the plugs - same issue
swapped the coils over - same issue
did a compresson test - 134 psi on both, happy about that!
Please help as ive hit a wall now and worried its something really odd/expensive...
Thanks
