Post # 36 is where I discuss valve adjustment. I have also discussed corrosion prevention early in the thread. I use airtool oil and allow to drain and repeat. then I run overnight with an aquarium airpump air into the engine via a lower cam follower guide and either venting out the carb or a removed upper cam follower. Works very well. The amount of condensate drained has been as much as a thimbleful from my 9-90! Gotta dry that water out. -Tom

Oke Maxam. It´s a little difficult for me to find the right words and then translate, but after reading the manual it,s clear to me. What i meant was, how comes the afterrun oil to all the parts of the crankcase. I know now the answer. By rotating the crankshaft several times the oil will disperce to the parts
is that right?
Regards,
Timo

Hello all
Please help me. I can´t make a decission what plane i gonna build for the 7-77 . I don't want an ARF. It must be a plane from plans. For example Ziroli , Jerry Bates or another designer. I hope I get responce.

Timo

Hi Timo,
Go with the Ziroli 87 inch wing span Stearman. It give the engine the exposer it deserves. Not hidden in a cowl.
It also helps with oiling the rockers and afte run oiling.
Good Luck

i don't think 30-35 pound plane is a problem for a 7-77 radial. I always look at the 7-77 as being the same as a 62 cc, the radial will swing a 24-12 prop and fly at scale speeds.

I have also seen the Corsair 100 inch from Meister Scale. It´s weight is 25 to 35 lbs. Is also a beautiful one, But I don.t know if the engine suits in the cowl. I have to inform to Meister Scale

Hello Tom.
Why is that? The Hangar corsair 60cc weights the same as the Meister scale though I thought that the Evo 7-77 fits the meister scale corsair in terms of the engine. Or am I wrong? Please give me your opinion.

Got my 735 back from Horizon. Carb rebuild and all new plugs for $60 shipped...not bad.
They me told me that I absolutely should be running exhaust pressure...anyone else actually try running one with it connected?
