79 EFNR Lives!
Posted: Sun May 08, 2016 4:09 am
Well, I got my 3rd Seagull running: the EFNR (Silver Century). Thanks to Michael for letting loose of one of his Mark III coils. Cleaned the tank, cleaned the carb, replaced the AMAL fuel line connecter and line, put in the new used coil, put on a new spark plug cap and spark plug.
I couldn't wait on the rest of the parts coming from John, especially the recoil starter screws and throttle lever, so I just used the rope starter and the broken lever for throttle. I had to pull the carb connector and clean the screen again. Engine still runs a little rough, but it was in the tank. Got a great stream of water, even near idle, so water pump flow is no worry. Shifts OK into and out of forward and reverse.
Q: Has anyone with a "pre-80's" Mark III ignition bothered with retarding the coil plate 5 degrees? This was in the Don Meyer book as a remedy for stalling when shifting into gear.
Also, I have both a champion D-16 and a D-21. The center insulator looks a little different. Is one hotter than the other?
Q: Which plug should I use? Most of the literature says D-16, but that a D-21 is OK. I ran with the D-16 (set at 0.35), haven't tried the D-21 yet. I sail at 7000 feet altitude.
The hardest part of this resurrection was the recoil starter spring. WHAT A PAIN IN THE REAR. It came nice and packed tight with tie wraps from Sean in California. I read and re-read the instructions in the service manual and the Meyer book. I'm pretty handy, but I sure couldn't figure out how to do it coiled up. Sure enough, I lost grip (yeah, I had gloves and glasses on) and sproing.
I ended up using the method in the service manual, starting with 2 small coils in the rope plate, pushing the plate on the shaft, and feeding the rest in while turing the rope plate. The end passed through the slot and clicked into its capture slot just right. Maybe I was lucky, but it worked. I have to undo the rope again and preload the spring one more turn, the spring doesn't want to pull the rope back unless I coax it. I can't use it until I get the replacement screws from John.
Now I have to build a 5" extension to my motor mount on my Potter to run the thing at the lake. We'll see if it's too big for my little potter. I'm hoping it will work, since I want the forward and reverse.
Thanks for all of the help you guys on this site provide. 3 out of 3 resurrected Seagulls all having been dead for at least 17 years. I'm pretty happy,
