    To answer one of your earlier questions, yes, that hole is supposed to be in that tube.

    Okie Dokie on the cleanup. Maybe a little ATF to free and clean up the sticky stuff.

    Been a fan of MMO since the introduction of lead free gas, in all of my older small engines. It eliminated sticking exhaust valves immediately..!! And an occasional additive to the crankcase, on certain ones. I still ad a dash when refueling my older tractors.

    I used to use Rislone years back also, as an oil additive.

    MikeR gave me a hand to take the manifold off today. I looked at the valve stems and they are COATED in carbon. I think I'll take the head off and give everything a once over and good cleaning before I do anything else. I'll post a pic of one of the valve stems soon.

    While you have the head off and the engine apart you should also deglaze the cylinder walls.

    Ya I will. Depending what the crank shaft looks like, I may decide to send it to a machine shop and to put new bottom end bearings into it.

    Sorry it took me so long to get these uploaded but I've been busy with a lot of different projects lately. Heres the valves and head. No major surprises. Theres definitely some seating issues but no obvious major problems. I'll update you guys again once i get them ground.

    I found a flattened piece of metal in the #2 exhaust seat. My guess would be that it is screen that was missing. But your right, there was no noticable damage to the seat.

    I've soaked the valves in "Super Clean" for 5 days and brushed them off with a brass brush. The exhausts on #2 and #3 still won't come clean though. I'll just keep soaking them and brushing them until they do. I just wanted to update you guys on my progress.
