well i have been pondering the idea of useing gasoline to power 40 sized engines.
realizing that because of weight and lack of power issues all gasoline 40 sized engines, may beout of the question?

so then i read about gas-glow, could it be a solution?
from what i understand here are the problems
lack of oil, a 2:1 gas to glow fuel doesnt have engough oil for the piston/conrod bushings
carb issue, need a gas carb since the fuel-air ratio is different than glow,
gas burns hotter which may or may not be a problem
needs a ringed engine, limiting engine choice
will the glow plug stay lit?
not as powerful as all glow engines

heres a few ideas on how to solve these issues.
i know their are oil's that will mix w/ methanol and gas (is castor one of them? i dont think so)but you could use gas for say 60% of the mixture, glow for 25% and oil for 15% (plus that in the glow fuel already)
what if you use e85 instead of gasoline, thatmay solve the carb issue since (from what i have read) e85 and glow fuel have similer air-fuel ratio's
will the plug stay lit on e85, or does the catalitic reaction not work w/ ethanol (if not could you just have on board glow that ran all the time?)
if so could you just run e85 w/ no glow fuel and a whole lot of lawnboy oil?

as for the power problem, has anyone tried running gas/glow on a wankel roatational engine, they do use a lot more fuel but produce more power than a pistonengine(if useing gasoline who cares about fuel consumptionratesin such a small engine)and they are "4 stroke" which gives them that cool sound

i am thinking of trying this w/ a super tiger g-40 ringed engine. its only 50 bucks, if it doesnt work ill just use glow (or will the gas totally screw up the carb?)

also
has anyone mixed small amouts of gas w/ glow fuel, say 5-20% and ran it secuessfully in a glow enginewith no mods?</p>

anyone tried this? any feed back on where to start? oil/gas ratio's?
i will break in the engine on glow, them try e85? maybe?
av8tor? any feedback, do you think it will work?

Basically I just don't recommend using Gas/Glow in small glow engines. Too many problems with the bushed rod and it's lubrication needs, the fact that the engine is designed specifically for methanol, etc. Overheating is a possible problem due to the fact that gasoline engines run hotter as well.

Also, I didn't personally have luck with E-85 in the gasoline engine conversions to Gas/Glow, but some here in the forum have had various levels of success with it. Do a search for E-85 in this forum.

If you are just looking to economize, one can mix small amounts of gasoline with glow fuel to stretch it. Just make sure you keep the overall oil content correct. If the particular engine has no silicone parts like some pumped engines have, it should cause no damage, and the needle won't be too sensitive unless you go to high percentages of gasoline. I would try 10% to start.

A much better way to "economize" is to mix your own glow fuel using strait mentanol (about $2.85 per gal) and then use klotz oil. No nitro...but use a good hot 4 cycle glow plug. Capt,n

their is no where that i have found to get methanol in the kc area. i would have drive 3 hours to get the fuel which would make it pointless. now if you know somewhere i could getmethanol i would much rather do that.
although if i could get a .40 to run on gas that may be a better for all of us. (key work.....IF)

Small .40 engines was run a lot many years ago back in the 1940 days. Most had a set of points on the front and many had a little lever to advance &amp; retard the timing. The oil used was real heavy and Texico was used maybe the most. The engines had thinner...but more fins on cyl &amp; head for good cooling. You may be able to use a Helicopter engine...which is set up better for cooling. You see, gas engines runs some-what hotter than glow engines. Just make sure the cooling is very good and use plenty of oil in the gas. About 20% oil. That means out of a gallon of fuel about 1/5 will be lubricating oil. That should help you out! Capt,n

On small(0.19 to 0.60 cu.in.) spark ignition engines we used 3 parts gasolene to 1 part #70 wt. non detergent motor oil.

Lots of glow converted to spark. Normal glow carbs work fine, just turn in the needles a lot more. The fact the engine is small means you don't need a pump or regulator. Its the size of the engine and distance of the tank not the fuel that requires the pumper carbs. I suspect it will work but you will need some methanol and a lot of oil so there will not be much of an advantage to mixing your on glow fuel. BTW use Bakers AA or synthetic oil from Morgans, Sig, or Fox and not Klotz. Good oil for around $20 a gallon.

Norvel has a .40 with a Turbo glow plug that seems to work well. The fuel is gas with 20 % Klotz Benol (castor). http://www.rcuniverse.com/forum/glow-engines-114/11287797-testing-new-nv-norvel-40-size-6-5cc-gasoline I think Evolution has a gas .60.
