Default Weber with 1.6 8v

First, I have done a TON of searching and no luck on my specific question.WEBER 32/36 DGEV I want to run my current weber and 1.3 intake setup on my 1.6 8v.
Im a noob and am swapping a 1.6 8v into my salmi. I have the redline webber kit for the samurai. Will the jetting be okay to just swap it over and then tune the idle and air/fuel mixture screws? Or do I need to get different jets? I don't exactly know what jets are in it (the ones that came in the kit). It hesitates currently (In the 1.3) when I dump the throttle in 1st and 2nd, but then evens out once I shift into 3rd. I hear of people swapping these over with their 1.3 intake to 1.6's, but does the 1.3 jetting run too lean for the 1.6 application.
What is a SAFE jetting to run for the 1.6 so it doesn't detonate?
If you are currently are running this setup, what jets do you have? I am also going to port the intake to match my intake gasket.

I can't help with the jetting, maybe Redline can advise you. When I did my original 8V conversion I used a 1.3 intake, I cut the 1.3 gasket to suit the ports on the 1.6 head and then flowed the 1.3 manifold to suit; the holes in the 1.6 gasket were larger than the ports.

So you took your 1.3 intake AND CARB off of a running 1.3, then swapped it onto your 1.6, WITHOUT changing any jetting? And it ran fine?

I had the same setup as Rhino until recently.

Unfortunately, the carb was professionally set up for the 1.6 so I never had to mess with the jetting. At this point, the folks at redline are your best source for 1.6 8-valve jetting information.

The other item you need to watch out for are vacuum leaks. When installed, you should have only one vacuum hose installed - running from the distributor advance back to one of the vacuum ports in the center of the manifold or on the carb body itself. All other vacuum ports on the intake manifold should be plugged with a brass bolt and/or JB Weld (or both). Steel bolts will corrode and leak air after prolonged heating and cooling. Small rubber caps may be cheap, but they won't last long.

i hope that this helps!

What about the vacuum line for the brake?
I'm pretty sure there is a line that goes to the brakes because aren't they vacuum operated?

do any of you guys know how to get ahold of Sarge? Right now I would be willing to just send my intake and carb to him and be done with it. Thanks for that link Rhinoman, but they are all talking about jetting for 1.3 engines. I have mine set up for a 1.3 now, but need the jetting for a 1.6.

Hey guys. So I am doing the swap right now. I have a 1.6 8v and am using the sammy intake and weber carb. Also going to use the 1.3 distributor. Do you guys know if there is any special way to set the timing of the engine? Or do I just time it to the 1.6 factory specs?

I set the timing to the 1.6 base timing, it will go forward a few degrees if you are using 95 Octane RON or above but if you have an emissions test to pass the base setting is the best start point.
I don't know if Sarge is still around the Zuk forums, he gave up the carb work a good few years ago because of ill health. There was a mega-thread on jetting the Weber carb on off-road.com, it ran to 120 pages or so! it was in the Toyota section but there was also stuff in there about jetting for a Suzuki.

Sweet Deal Rhinoman. I wasn't planing on running any serious octane or anything, but I guess I can. Thanks for the lead on that link.
