$84.40 was what he charged me for a huge parcel of bits.
Even though they're cheap cars to buy you can't rebuild a Beta on an shoestring. You said an electric fuel pump was too expensive - now shipping is too expensive ?? Both are a lot cheaper than trying to make twin 40s work on a VX engine !
You want a decent bottom end that's going to last, you might get lucky on Ebay but a more reliable route is to acknowledge that a few hundred quid will mean you don't worry about it for many years.
