yeah it just stays stationary like the bass tracker jets. then you have a diverter on the back right? its a 175 optimax powerhead. i wonder if thats just
used unburnt oil??? where does the exhaust come out? what do the plugs look like?

ok now can get started and look at the plugs, it smokes bad couple minuets first start after siting weeks then no smoke and exhust may vent thru this intake grate so I hope thats it, I will look, thanks.
