Pelle,
 
For auto gas and methanol, you need to stay with Buna-N {Nitrile}, which is probably what was in there to begin with. It's a good idea to change out if you can because most rubbers have a sheilf life of 5 years. Buna-N, or Nitrile, also goes by the following trade names: Chemigum, Hycar, Krynac, Nysyn, Paracril and Perbunan.

I would think if its safe for nitro, its safe for meth..

I've replaced all "old fashioned" rubber!
The basics must be the same as for nitromethane?

i would guess bigger jets in the carb...isn't methanol really tough on some rubber parts ?? maybe some racers can jump in with more info..

What does one need to do to convert an old 402 to accept methanol only?
Right now I'm trying a 30/70 methanol/gas mix that works just fine but with
a slight power decrease since the alcohol contains less energy.
What do I need to do to run 100% alcohol?
Here in Sweden at least, the methanol fuel is slightly cheaper than std gas
and the price gap is increasing so...
 
Best regards
Pelle
