Interesting that apparently some .60 size glow engines have room for a Walbro carb. When fitting a Walbro carb to my Super Tiger .90, I had to grind away at certain areas of the front of the engine, and turn the carb slightly sideways to get it to fit.

I still don't recommend converting glow engines to gasoline, but if you are determined to do so, here's a hint. The Zama carbs have somewhat smaller outside dimensions than the Walbro carbs.

For people who want to go the other way, converting a gas engine to alcohol or glow fuel, the WT-499 Walbro carb is made for use with alcohol and has larger fuel passages. When converting a gas engine to alcohol, you will usually see a nice power gain, and the engine will run cooler as well. You should check on the availablity of menthanol in your area if thinking of doing this as some people have problems finding it. It can usually be found at automotive speed shops, or at go kart racing supply outlets. An engine will consume double the amount of methanol than it does on gasoline. (Your airplane fuel tank will last 1/2 the time it would when running gasoline.)
