Default 87 Samurai Emission Delete Question

I'm putting a Weber 38 Outlaw E-Choke on my 1.3 liter Sammy. My state doesn't require emissions on a vehicle this old.

Can I plug all the vacum ports on the intake manifold? Any suggestions would be appreciated.

Thanks

plug all but power brake booster and distributor vacuum advance. if you use the little rubber plugs that come with the carb kit, fill them with silicone first (they fit too loose) I usually make a little plate out of scrap tin or plastic and remove the EGR valve entirely (for aesthetics)

btw - I think you're gonna find that 38 to be way too much carb for a 1.3l unless you've done work on the valves. Advance your timing as much as possible.

Thanks Figmo......would you prefer the WEBER 32/36 as a better option?

yes, I think you'll be happier with the 32/36. not just the size that makes the Outlaw too big for a 1.3l, but also it's a synchronous carb. it doesn't rely on vaccum to open the secondary barrel, it is geared. this is normally a GOOD thing on a performance engine, but the stock 1.3l just wont be prepared for that massive rush of air/fuel when the Outlaw starts pushing it into the intake.

I've built one "Outlaw" 1.3l in the past. to do it, I ported the exhaust valves on the head to use 1.6l sized valves. others have used 1.6l 8v heads on their 1.3l block to achieve this.

which works....but at that point you have to ask yourself "why not just do a 1.6l (or whatever) swap if you're gonna go through all that?"

for under $200 and an hour of your time with a couple tools you already own.....you really can't beat the power gains and simplicity of a Weber-type 32/36 carb.

Figmo...a quick question.

What is the 3rd nipple coming from the gas tank towards the front of the vehicle?
I know ones the Fuel In one the fuel back to the tank. What's the 3rd?

the 3rd line goes to the charcoal canister on your firewall. its a CA emissions requirement that filters gas fumes from the carb. it does not carry any fuel, just a excess fumes filter.

I normally delete this line (and remove that canister from my firewall)
