Engine is Running

After my attempts to get things going without success I pulled the carb and soaked it in cleaner. Then I installed a carb kit and put it all back together. Setup my test tank (just a garbage can full of water) and tried to start it. No fire, no cough, nothing !!! Then I realized the plug wires were not installed on the plugs !! Arg. I installed the wires, hit the key and she fired right up to a nice smooth idle. 

Picture of it running showing my test setup.


Here is some video of it running.


While the engine was running at idle I shifted the motor into both forward and reverse gear. All seemed to work fine there. After the engine run I drained my test tank. The lower unit was covered in exhaust goop. Gear box was ok. Picture of lower unit after test run.


With the test run complete its time to finish up the trim details and start putting all the cowling parts back on the motor.

Carb Rebuild

After a second attempt at getting her to start, it was obvious that something was wrong with the carb. Fuel is just dripping out of the carb body. Called my local dealer and they actually had the carb kit of the motor. On the way back with the kit I grabbed a gallon of chemtool parts cleaner. The carb came off easy enough. Then I removed the choke pressure acctuator, and the float bowl. The float was in pieces and the needle valve was shot as well as the fuel inlet valve. With it completely apart, all the parts went into the basket and then into the parts cleaner. Then I walked away for 24 hours. Next day I pulled the parts out and all the old crud and paint were coming off. Over to the sink and lots of hot water later the parts looked brand new. Back to the work bench where new parts from the carb kit were installed. Carb was reassembled and made ready to put back on the motor.

Tried to start the motor

Well, I got the motor all wired up and the rebuilt starter installed. Primed the gas lines and made sure that everything was tight and no leaks. All looked good. With the plugs out I verified that there was spark on both of them. Decided to spin the motor a little more before putting in the plugs to pull fuel and oil into all of the bearings. It has been a while since she ran. Then I installed the plugs and left the wires off. Starter turned the motor over nice and smooth. Installed the plugs. Moment of truth. After a little cranking she back fired again and again. Hmmm. Advanced the throttle a little. After a couple of tries and working with the joke I got a sustained run for a few seconds but then she died. Figured I was starting to make some progress though. Next time I went to start though, the starter just spun the fly wheel. Suddenly I realized my mistake !! I forgot to install the fly wheel nut !! Yes I had done some checks on the ignition system but I forgot to tighten the nut. So take it apart and sure enough the woodruff key is sheared. Decided to pack it in for the evening. Here are some photos.

My test stand and test tank.




What is left of the woodruf key after a couple of starting attempts with the fly wheel not properly tightened.

Looks like a motor again

Got the motor hanging back on the pan then replaced all of the rubber hoses. This is a very important step. The hoses that were there looked ok, but they were all very rotten.



 
 Shop also called saying the starter was ready for pickup. So at this point the plan is to mount the starter and then get the wiring figured out. Then turn her over with the starter to confirm that I have a good spark on both cylinders. Then time to see if she will start.

Putting the motor together

Installed the pivot parts today. Slid the lower motor mount on to the tilt mechanism and then installed the nylon bushings and lower snap ring. Next I slid the main shaft into the bushings and installed retaining bolt. When this is all done you get something like this.
Next I took the motor pan and bolted it to the bracket. Then started installing the other bits and pieces. Several of the little bits and pieces needed painting.
Once you get it together you get something like the picture above.

Tilt / Mount Assembly

With the parts painted it is time to start putting the mount back together. The first picture shows the two exterior brackets.
This next photo shows the interior  mounting bracket ready to install along with the lock and unlock lever

So now the idea is the lever has to go into the little slot on the front of the interior mounting bracket and connect to the rod that locks and unlocks the motor tilt. So you slide the lever into place and it hits the various pieces on the bracket. And guess what it does not work. So I fiddled around with it and finally figured out that the lever does not go in straight, it goes back into one of the pockets. The picture shows how the lever fits back in there and hooks up to everything.

You will also notice in the picture that one of the side brackets is already installed. This just makes it easier at this point. Next slide the lock bracket into place and slide on the other bracket. Then put the retaining nut in place. The end result from the backside should look something like this. You can also see the spring that keeps the tilt pin lock in its proper place.
So here it is all back together and ready for the next step of assembly.

Paint Showed up

The paint came in to finish working on the motor. Sprayed the center tilt assembly with a couple of coats. Hopefully start reassembly of the main motor mount section this week. By the way I get the paint from this website. http://www.nymarine.ca/ Check it out, he has all of the color charts for all of the various years of the motor as well as having all of the paint available. Easy to work with over the phone or via e-mail once you are an established customer.
