Greetings,
I’m planning to put a 2.0 in my 79 Westy. I’m unhappy with the Weber progressive single and am convinced that Gordon my duel carbs is the way to go.
Any inputs on the best performance / value of carb kits to use?
Reliability and daily driver for in Florida is the mission.
Many thanks. |

I live in S.Florida and have dual Dellorto 40s set up by Blackline Racing on my 2.0 in a '78 Westy. I like them. |

I thought Dellortos were long gone. The 36’s were a good choice for the Type 4 engines, but I think are very hard to find. Weber 40’s are popular too. I run original Solex dual carbs on my 2 liter, but I would not point you in that direction. The progressive is workable with some tinkering, but you would do better with duals. |

FI works really well. Also the last thing you want is the carbs dueling with one another. |

I made the switch many years ago from the 2 barrel progressive to dual 40mm IDFs. I have an in cab vacuum gauge. Manifold vacuum with dual IDFs will be 1/2 of what it is with a progressive. Ported vacuum for the dizzy is essentially zero when driving. |

Thanks all for the great info. And thanks for the spelling humor; always have a 50/50 chance of getting that one right!
Next question since I may need to go another route with my type 4. Can I put stock 1.8 pistons, rings, jugs and heads on a 1.7 block without cracking the case?
My 1.7 runs smooth but lousy compression all around.
thx.[/i] |

Excellent. I’m investigating that route to repower my 79 Westy.
Thx
