carb relocation

RE: carb relocation
On reed valve engines you can place the carb about anywhere on lower crankcase. You can even add carbs. I have seen as many as 3 carbs on a Mac...go-cart engine. What did you have in mind? Most people do not like the carb sticking out so far. Yes elboes can be made...but it takes time to get it all right. Good luck, Capt,n

RE: carb relocation
I was wandering about elbows on side mounted carbs, moeve 'em round back and trim up the package.
My little weedy test engine would need about 4 inches of intake.
Think it might work like a high rise intake? velocity draw?
I've seen several planes in here that have great looks ruined by a big ugly carb hangin out the side of cowl.

RE: carb relocation
How about installing a Ryobi rear cover with reed valve into a Homey 25? I need to measure this. Put a cover plate over the old intake port. Maybe a Mac 28 or 32 would be a better fit. these are much better quality engines then the Ryobi and can rev higher without coming apart. I was just kidding, Ryobi's are cool. I have a few myself.

RE: carb relocation
I tried it and the Ryobi rear cover is a good fit. The depth is right on and only a minor realignment of the mounting holes is required. A spacer may be needed inthe back of the wrist pin to insure thta the big end of the rod doesn't hit the reed stop.

RE: carb relocation
That answer is pretty simple...some people do not like a big carb sicking out through a nice cowl. Not everyone is out for all-out performance. Capt,n

RE: carb relocation
Captain,
I am not planning on doing the reed valve thing soon. It was just an interesting idea.
av8tor: The only reason for doing it is to move the carb to a more pleasing location on a scale type model. It should run better then a Ryobi, since it can rev higher without exploding. The operation is totally reversable and would only require minimal effort to do. It would even be fun.

RE: carb relocation
Is there any difference from a ryobi reed valve and a stihl? As was stated, I don't like the big ol' ugly carb hangin in the wind.

RE: carb relocation
The ryobi reed valve is a basic item. It has a 5/8" bore, which matches the big bore carb throttle bore. You can bend the reed stop out a bit to allow a greater opening. Just br careful not to allow it to contact the moving parts. Fancy reed blocks are available and could be mounted in the stock rear cover. You might pay more for one then you paid for the motor though.
