Fuel leak help please

Hey troops,

I have had issues with rusty fuel tank which has now been sorted.

All back together and ran up to temperature a day or two ago - no issues.

Started today on choke, then to half choke, a short while later it stalled before i could take off choke.

Now wont fire at all, fuel leaking out from bottom exhaust join, and from front plug behind oil cooler and now from an approx 10mm hole in the side of the crankcase.

Anyone tell me why this might happen and what are the holes near the top of the crankcases!!!
So far i am missing around 4litres of fuel somewhere in the engine internals !!

Thanks

Hahaha yes and sadly not that much of an easy fix.

I've taken the plugs out and just syphoned off a cup full of gas.

Bloody stuffs everywhere.

Thanks for your reply Vnaik

I bet you the fuel pressure regulator is gone, flooding the cylinder pretty good.

Replace fuel pressure regulator
