We run glow fuel in our race engines all the time.. We raise the compression and do some port work for higher rpm....No problems with seals or carb parts, just replace the diaphragms when the carb quits working like it should..The fuel passages in the carb need to be enlarged to twice the area, not the diameter......We ran the same glow plugs for 2 years in a 289cc race engine, using up to 22% nitro...
You WILL need to run glow fuel..
A stock G26 runs 600 rpm faster on glow fuel, using either stock ignition or a glow plug...
You can run 50-1 oil ratio with the methanol....
