Crash Dummy, the only problems i had with petrol and methanol was getting castor oil so it would mix with the methanol .... otherwise its stayed mixed fine as far as i can see ... but i don't want to have to mix it all the time, hense why im gonna go straight methanol once i use what i have already mixed up.

its not specifically a methanol carby, the only thing really that makes it different from the others is the primer bulb .. i got one of these off a whipper snipper with a primer bulb and stuck it in methanol for a while to see what would happen ... after a few hrs the primer bulb was starting to break down and eventually split etc .... all the other gaskets and parts were fine, hense why i got the 257 as it didn't have the primer bulb.
