Having the engine on a proper timed ignition is very desirable. The glo plug is not really suitable because the timing is uncontrolled. Reducing compression ratio and retardation and advancing timing is crucial to prolong engine life...Get it on an ignition system is my advice....🤔🙄😳🇬🇧

Another brilliant video. Love the graphics at the start.i think this experiment is a good idea as it also depends on the use of the engine. For a uav application to save lives a more simple setup and efficient set up like this with a longer range is better. Maybe gasoline is not the best for the engine to last forever but for uav application if it lasts for 20 missions the positives outweigh the negatives. Also if the uav is not designed to come back home it doesnt matter. Its good to see you push the little engines to there limits only then can we learn and understand them. Great work .

Hi, Saito glow engines don't use bearings on connecting rod, gasoline is less "dry" and give a little lubrication compared to methanol and maybe this can help; an investigation after some tanks could be interesting. Thanks for this experiment.

Not really worth it when you factor in how short the engine's lifespan will be and how easily it will throw a rod. These conversions overstressed the engines in three ways. 1: Excessive heat load. Gasoline burns way hotter than methanol/nitro, which means the engine will effectively be overheated at all times. Glow engines generally don't have enough fin area to deal with this. And you're encountering some of this as well. 2: Oil ratios are too thin. Gasoline typically runs a 25:1-100:1 ratio of fuel to oil. Glow fuel is usually in the 4:1-7:1 area. Saito engines are designed for the latter, with plain bearings in their conrods that rely on a ton of oil blowing past the ring that just doesn't happen on the super thin fuel/oil ratios of gasoline. These engines are RELIANT on oil mist blowing past the piston ring to lubricate themselves and that requires a lot more oil in the fuel than even the 20:1 brew you're running here. Saito's gas radials, in particular, are bad about throwing rods because of this. 3: The leaner AFR of gasoline over methanol/nitro further starves the engine of oil. Not only is the oil content of the fuel way way WAY too low, but the amount of fuel running through the engine is a mere fraction. This is why people try to do these conversions...cheaper fuel use less of it....but it's also what kills them. Saito has enough trouble with the gas engines they sell exploding. I never advise converting ANY Saito glow to gasoline. It may run sweet now but it won't last very long.

I enjoyed watching your video very much. However, I could not understand the brand of the carburetor you used. Is it possible for you to specify the brand and model? Additionally, where can I buy it?

You should make a spacer with some G10 between the carb and its mounting flange. Heat from the engine will migrate into the carb and throw off your carb settings.

Grab a asp engine and check out their conrods, brass bushed they are, asp fs91, converted to gas stock glow carb..it runs absolutely perfect, and smooth idle after breaking it in..

Hey mate sorry for the no show of late. KZfaq seemed to think that I no longer needed to see these vids an decided to stop showing the notifications for them.

The bigger the glow engine the more methanol they use! Conversion to gas of 4 stroke engines is no way a bad idea, i run a saito fa120r3 converted, yes plain aluminium conrod journals, woop di do.. i started break in at 15 to 1 roughly 65ml per litre oil..now im running 40ml per litre. 10lt of fuel so far..i run about 1 litre per week and this engine is awesome..i run 20min air time and it sits on full throttle most of that, 8500rpm on the ground. So with the wind would hit close to 9000rpm..sure the engine runs slightly hotter than glow,but definitely not excessive

Asp ft160 converted to gas..this engine took some time to break in and get it reliable, this engine and the others converted so far they all produce plenty of oil waste out the crank case, despite being a lower oil content,the gasoline vs methanol, gasoline has much better lubrication over the methanol hence the need for way less oil content over a glow/methanol fuel.. ..go scale down a single cylinder motorcycle engines cooling fins to the saito cooling fins..example a xt600 (4" bore) Saito fa180 (1 1/2" ?) Then compre the scale? It has been proven that a converted glow engine can give many years of engine life, dig deep and find the right conversations on forums, youl see
