AFAIK, when running ethanol, the engine requires more volume of it.
That's why valves and rings get burned. The engine is running way too lean.
Check the air fuel ratios of the different fuels. You'll see what I mean.
You might have to run a different carburetor.

i know they recommended running forced induction via street bike turbo for ethanol burners i think i might have to put different rings and valve seals in too

I think it takes about twice as much fuel if you're running straight alcohol (did the research some years back). As I recall, it was said to measure the diameter of the jets in the carburetor and make them 40% larger. Also the engine would be able to make even more power on alcohol if you could bump up the compression ratio a little bit. The alcohol has a higher resistance to detonation. Aside from that, the alcohol is lighter weight and so there was some adjustment that may have to be made to the carburetors float, spark timing, and maybe even changing to a hotter sparkplug.

my buddy used to take his kids in JR drags. 5hp B&S engines spinning 25hp on methanol.
you'll need a carb capable of running methanol. jets will need to be at least double that of gas. to keep your rings, you will need to change oil meticulously.
the JR drags was every run. this is because there is so much fuel pouring through, they never heat up.
best bet is to find a shop that deals in JR drag engines and they will be the best source of info.

i'll ask him in the pits tomorrow if he knows what was done to the standard carbs to stand up to methanol.
i think it doesn't play well with brass inserts, and they must be changed to something else, but i'll know for sure tomorrow afternoon. i'll reply when i get back from the races.

Keep in mind, alcohol dries out rubber components so you should keep that in mind. I know that in the mid-90's when they introduced ethanol in gas that many cars and toys not designed for the stuff were going through rubber fuel lines and other soft parts.

well, i asked him yesterday, and, well, no more knowledge than before. he bought the cars/engines already done, and knew they were jetted for alcohol, but didn't know about particulars.
he used to run gas through at the end of the race weekend to help against corrosion from the methanol.
your small engine builder will probably help you best. you'll need to find one knowledgeable about running these on alcohol. the ones i'm talking of are running straight methonal.
if you wish to run only about 10%, your carb should probably have enough adjustment in it for that.
otherwise, your carb will have to be re-jetted for 100%.
