1975 135HP Johnson
Well I finally got the boat in water and ran it for a real test. Started relatively well (Only three tries!!!!) and would idle with the motor submerged. Idle rpm was just under 700 while in neutral, when I put it just in gear the rpm's would drop to about 400-500 and the engine would stall if I let stay there. I went through a series of low speed and WOT runs and the engine seemed to run a little rough but not bad. WOT topped out at about 3100-3200 rpm ,which is low from what I understand. I've got plenty of questions on my next stage of tweaking this thing out but I have a quality of service question to handle first.
I had my boat in for a tune up and it still did not run well. Then i started doing all this stuff myself with the help of everyone at this site. Over the past few weeks of learning about my motor and having lots of fun and frustration along the way
I now notice some issues with what was done to my engine during its tune-up. I have two problems both with the lower carb and maybe related. There is now always a puddle of fuel under the carbs and the gasket surrounding the lower carb is always wet. I can't see an obvious indication of a leak elsewhere but haven't ruled anything out just yet. I also noticed that there is no gasket between the lower carb and the silencer. There is one on the top carb but none on the bottom. I don't think I'm out of line to bring that in for a re-do but is such a booboo even acceptable?
Will the missing gasket at this location cause any performance problems? what would be a 'reasonable' response from the repair facility (one-man show)?
