New Ryobi 4 stroke glow conversion

Brand new Ryobi 26 cc 4-stroke, only three tanks of fuel through it for break in. Does is have enough power for r/c use? I tried a different carb as the stock one is non adjustable and horribly lean.
After finding my 7mm Walbro a little less than optimum from a swelled diaphram, I discovered the stock carb can be made to work rather well!
By opening the fixed main jet from .012 to .0145,the engine will hold wide open throttle 6100 rpms with a 18X8 wood prop.
Transition from idle to open throttle seems smooth enough as long as the throttle isn't snapped open.
These engines may have potential. I haven't carved this one up yet as I have another one I"m working on for r/c use.
This engine sits on my bench swinging a 22X10 prop as an outdoor fan in the hot summers.
Cheap to run and the prop is noisier than the exhaust!

Yes, it works as well with a 2 stroke. I used a common #3 plug.

With glow plug and glow fuel, you can loose the weight ofthe magneto and flywheel, with glow and gasoline you need a small glow battery to keep the glow plug energised, but still less weight than a mag and flywheel.

I have converted Homelite 25's to glow and they run fine with a prop for a flywheel and a glow plug where the spark plug once was. If you use glow, the glow driver is used only for starting, but if you use the gasoline/oil mix you will have to power the glow plug continuously.

For a boat application you may want to keep the flywheel so it will run.

I just got the same exact engine for $40. How many cc is the engine? Mines 26.2cc I just want to know so I can try modding my carb like yours to 0.0145 since my engine runs very lean at full throttle.

This is a 26 cc engine allso. I don't know the history of my engine, it may have a high altitude carb which would explain the lean main jet at sea level. Opening the main jet to .0145 definately made the engine run better.

just a thought for more power as it looks like you are trying to get....see if you can locate a gasket kit and if so try to port and polish the cylinder or just build up some kind of long tube header

Would the glow plug conversion work with a 2 stroke? And what size glow plug were you using?

Thanks

neat!

whats the advantage of glow over spark?

[theonethatgoofs]

ill half to figure out what weighs more a stock flywheel or 1 d battery for the glow igniter

[theonethatgoofs]

will this work on a 2 stroke engine .i blew my old nitro max 46 marine v and the piston and sleave and rod is around 100$ but i got a tiny 2 stroke . can i convert it . if i can loose the fly wheel it will fit in my twin pontoon hydroplane and not be too heavy .

cool
