Leave it on methanol, Jim You WILL blow it up on petrol if ya frig around.

 The old story, Methanol must not run lean, but it will work up to 30% rich. Petrol has a leeway of about 3%, leaner than that = holes in pistons, richer means runs upta s**7!

I agree, my TM seems to be rich on the meth but has more power than the other Petrol TM's so i will leave it alone. U got meth Jim? I have plenty of 20lt drums if u need one... think cost me about $1.20 per litre as I went halves in a 200 litre late last year and straight away decanted into 20's.

Make sure the 200l is well sealed as methanol attracts moisture out of the air.
