My son has a 51 plate gilera runner, the other day he ran out of petrol and pushed it a few hundred yards to the petrol station and filled up but then would not start. Since then for the last few days i have been all over the bike trying to get it to start, i bought a new spark plug and the spark looks good, new inlet manifold (as i thought the old one was leaking slightly), pertol flows through the carb fine, i have changed the jet from the 76 that was originally in it to a 60 and then a 65, its has good compression and bore is good.
What am i missing?
