Can any one help, I have a honda 6hp that starts easy but after running for
about 30secs it seems to slow down even when warm. The bottom cyl I think
is the problem as when I take off the plug lead the engine keeps on running
but does slow down, when done on the top cyl it stops. Compression is 120 psi
on both cyls, Spark is good on both and the Carbs are clean.
