I finally got my 115ETLK Yamaha V4 reassembled and started last weekend. With the advice and reassurance of rodbolt and Ray and the gold mine of information available here the overhaul was not hard, only time consuming.
I started it on the muffs. It took several 10 second cranking sessions before it started. It would fire once, disengage the starter gear then die instantly. After it was running once, it would restart easily. I ran it maybe an hour total before the weekend honeydo schedule brought outboard work to a halt.
It idled at about 1050-1100 with a significant miss. It is running on all cylinders as I got a drop in rpm when I pulled each plug wire. A squirt of gas/oil mix into each carb throat produced a drop in rpm. After it warmed up, I checked the compression on each cylinder, they matched perfectly at 90# on a known badly calibrated gauge. The plugs were each wet with gas but of course it has not run enough for their color to mean much. While it was warming up, I bled the oil pump.
I was careful to preserve the various link shaft lengths, etc, but I found the pilot screws set about 2 3/4 out where the seloc manual calls for 1 1/2 on this motor. I suspect that the previous owner had been fiddling.
So, should I run through the timing and synchronizing chapter in the manual first or should I just go ahead and order the carb and fuel pump parts and overhaul them first?
Thanks!
