Hello everyone.
Cub has started smoking a bit of late and I am going to do a leak-down test soon when I get a break in the action 'round here. Engine is a Kohler Command CH18S. I suspect the head gasket on number 1 (and perhaps number 2 as well) needs replacement. I'll know after I do the test of course. Likely it is that or a valve issue, either way requiring removal of one or both heads. Never been down that road, and seems straightforward, but one issue is bugging me and I would like to get clear on that before diving in.
I've watched many a video but remain unclear on the intake manifold disconnection. Does the full intake manifold, carb etc. have to be removed to get the head off, or can I just disconnect it at the entry to the head? Appears removal of the entire thing would mean removing an additional shroud and dealing with some hard-to-get-to bolts. Hoping to keep things simple here, removing as little as possible. Normally I would just take it to the shop, but hate to be without it for six weeks or thereabouts at the beginning of summer with sevral acres to keep mowed, plus I would have to haul it over there and bring it back, and it would have it sit out in the weather awaiting its turn in the shop.
Can anyone provide clarification?
Thanks, Steve
