Hello, all. New to the forum and to boating although I dive boats for cleaning and repair.
I have a 1967 39 and have rebuilt the carb, fuel pump, ignition and water pump. I have experienced this motor will not run with the tiller grip all the way to the right (in the area marked "shift range") it will idle in the space between "start" and 'shift". Shouldn't it idle throughout the entire range? I feel it should, and if someone could weigh in here I can know whether to mess with it or leave it.
The grip all the way right or closed and the throttle pin is not in contact with the mag cam so I feel the butterfly is fully closed. There is no spec on how much of a gap should be on the butterfly so I am not sure if it should run in this position or not. It runs well after warm up and idles as I described, shifts easily in f-n-r and pulls hard. seems like it is going to be a good little motor as soon as I learn about it. Btw I pull the cowl after starting to adjust and check the internals. Go easy and practice removing it before starting and it is painless. (it does scrape a bit, sort of like playing operation, also I was able to hand roll the motor enough to check the spark fyi.)
I went by the carb schematic and there was the idle jet gasket missing so I replaced it, and the float needle jet is Viton tipped with a solid seat, rather than the solid needle and Viton seat it replaced and I did reset the clips to the proper specs. I don't know if this could cause float level related problems but the old seat was shot. It misses at idle a bit when cold. if this is normal? It idles great after warm-up.
So my question is that shouldn't the motor idle throughout the range and since it doesn't, does anyone have any suggestions or settings that will help?
Thank you.
