Hi all,
I've got another old Mustang, this one has a couple of problems.
The first issue is that when trying to pull start it, sometimes, the pull starter doesn't catch and the cord just comes out and goes back in with no resistance. I removed the pull start mechanism and checked that everything appeared to be in place as it should be. I found that the clip had actually come out, but I put that back in place and tested again. It appeared to pull start normally a couple of times, but then it went back to not catching. I haven't removed the pull start mechanism again to check again. The spring is always working though, retracting the cord as it should.
The second thing is that it's not kicking over when it does catch. I've confirmed that the spark plug is firing, so it must be either a compression or fuel supply issue. When I removed the starter mechanism, I noticed that the pull start mechanism appeared to be almost entirely dry. At this point, I'm thinking it's an issue with the supply of fuel. I rebuilt the carby and re-installed it, but still nothing. I have a spare carby I'm going to try putting on as a test to see how it goes, I'll let you know the results once I have.
Finally, when the pull start does catch and rotates the engine, it seems to be a bit jerky, a bit difficult to pull start. It feels like the decompressor isn't on there and instead I'm trying to start with full compression. That said, I have experienced the same issue with not only the original decompressor, but a brand new replacement I put on there. Does anyone know why this may occur, other than the decompressor?
Working on this mower so far between worn parts and troubleshooting, I have:
-> Replaced both manifold seals
-> Replaced the carburettor cover seal
-> Cleaned the needle and seat (The cover was originally spewing fuel from the primer bulb and is now not)
-> Checked that the main jet is clear
-> Sucked on the diaphragm cover hose to confirm the carby will hold vacuum
-> Replaced the blown head gasket (There did not appear to be any wear in the cylinder)
-> Replaced the crankcase seal
-> Repaired the pull start spring
-> Confirmed the pull start mechanism is assembled correctly (Twice)
Has anyone ever experienced the pull start mechanism/clip being faulty/wearing out/coming out of place?
Cheers in advance,
