I acquired another 1998 Johnson 15 hp (J15RLECR) last weekend, but that's a story for another thread. Thank you all for your help! Especially to the Admirals.
I finally think I have identified the problem as being low compression. It shows around 75 for both cylinders. If I add a little oil to the cylinders, the compression increases to around 90. At this point, I'm fed up with trying to fix the motor in home conditions.
Thank you very much, sir! You helped me disassemble and remove the shaft. It wobbled slightly, probably due to the lack of a bushing, which would have created a gap with the follower. However, how can I adjust the gear throttle (#73) or break the hard link to turn the magneto without using the...
Sorry for the confusion — English isn't my first language, and I initially misread your question as being about the spark plug gap rather than a separate spark-gap tester test. I understand now that you're asking whether the spark can jump a 5/16" air gap on a tester, independent of the plugs...
Do you mean that if I remove the clamp collar holding the shaft, I'll be able to disconnect it from the lever? (photo-7)
Quick clarification — when you say 'the cam under the mag plate has a mark', do you mean the mark is on the breaker/armature plate itself, or on the curved cam piece (the one...
That is exactly the problem. When the handle is at the 'start' point, there is a 0.5" gap between the cam and the follower (see photo 1). I ordered a throttle control gear (part no. 0324512) to reduce the gap, but this was not enough. How do I adjust the meshing gear on the handle?
Hi folks,
I'm newbie in the Johnson motors and met the next problem:
Working through a full rebuild on this motor — carb rebuilt, fuel pump rebuilt, points gapped at .020, spark good on both cylinders. Motor starts and runs fine at FAST but won't hold a stable idle; throttle plate barely opens...
