Just found this forum, seems great, so my first contribution before I start asking my question is to show you this site where you can find most workshop manuals
for Yamnar engines..
Ok, now to the more important stuff:
When starting my 3gm30
, cyl nbr 3 needs about 15 seconds before it runs smoothly, and when it starts, it runs "harder" then the other two. It like it is knocking harder. I found out that it was cylinder nr 3 by lifting the decompression lever when the engine
For every cylinder the hard sound was still present, but when lifted it for cyl 3, it got more quitet and the engine
ran on 1 & 2 but more smootly.
Is this fault mechanical, or can it be so "simple" that it is the fuel pump
that delivers wrong amout of fuel
to it compared to the other two cylinders? Or something else.
All tips are really welcome..
