Nope, the magic mix to run GAS/GLOW is 1 part 10%nitro / 10% oil glow fuel mixed with 2 parts PREMIUM gasoline, Zenoah makes an adapter to go from a standard sparkplug thread to a glow plug thread and an OS F 4 stroke glow plug is used. Most ZAMA carbs do not like the alcohol but a Walbro handles it just fine, the only thing you really have to do to the engine is richen up the needles a bit. Run time is close to running straight gas, and on most engine you will see an RPM increase over straight gas/oil. For more info scroll down to the ENGINE CONVERSIONS forum, there's lots of good reading in there about this. This set up runs just like a normal glow engine, lite plug, start engine, remove plug ignitor and go, you get very low idle running GAS/GLOW, no onboard batteries for ignition, no RX interferance, and #1, less weight.

As for how much i have in this engine, i'd say about $18, the weedeater was found at the curb on garbage day ( FREE ), glow plug adapter ( $9.99 ), OS 4 stroke plug ( $7.99 ) and a few hours cutting and shaving the excess material off ( FREE on most days ). The prop adapter was made from a pc. of 1" aluminum rod that i had laying around the shop and the mounting plate was from a scrap of 1/8" aluminum i had laying around. It's kinda funny the most expensive thing on that engine is the prop ( $10.99 ).
