RE: The Plan
I have a question is forty dollars extra for a large bore carb worth a few hundred extra rpms. I know the philosophy of converting your own engine is to say, you did it and it saves a few dollars if you add on a carb, Ch ignition, aluminum pitts muffler and the rest of convertion parts and you're up to the price of a G26. I know you can save a few bucks using CH's build your own ignition module kit.
I have a perfectly good large two stroke commercially made engine. I am experimenting with gas, because I am curious about all the hubub you gassers are so sold on. Jag engines says, to leave the carb as is, because the rpm gains on a new 31cc Ryobi are not worth the extra money for the large carb. I am going to convert one soon within the next few weeks, I will have the fly wheel turned down and order a conversion kit from one of the online machine shops.
Good luck to you, happy smoke trails,
Will
