Re: Ye Old Fuel Tank Puncture

Re: Ye Old Fuel Tank Puncture

No pics as I don't want to remove bolt from hole. Really the hole is naturally partially plugged by the bolt.

When cold it would start and then the carbi was basically flooding the cylinder head with fuel. Wait long enough and you could fire it up again and then she would ...
