-> dragon_cb_cz: has true...you have to be very careful while tightening Jikov carb to the inlet manifold. I tends to bending. So you have to tighten it gently. For air filter housing I do not use original screw joint, but rather "makeshift" holder made from two springs. I can provide some images of this solution.

-> Christopher: The Weber's main advantage is better reliability and longevity - the Jikov is made from a zinc alloy which is not very tough, so if you tighten it too much to the manifold, the bottom flange will bend. Also the way the filter housing is attached (by a screw into the carb's top cover) sucks. Again - if you tighten the screw too much, the cover will bend, causing all sorts of trouble. But if you're careful with them, they work just fine (if you get a good piece to begin with - they're increasingly hard to come by).



BTW, you can use the " [nick] [datum] [oboje] [citovat]" links in the message heading to insert people's nicknames etc, it's faster 4

I acheived slightly better fuel economy and engine power with Weber. On the other hand it suffered from poor warm starts because it has no fuel disconnector solenoid. Starting warm engine with full throttle was necessary, because rich mixture was remaining in the inlet manifold when the engine was stopped...that`s my experience on 1.3 (1289 ccm) engine, but someone else might have avoided those issues.

Dragon,



Thanks - I do use Skopart and he's been very reliable for me. Shipping is cheaper too than ordering from the UK. So it's been Skopart/eBay/what I can find local that keeps my cars alive...!



Ozzman - that sounds right, I bought it from the UK. Is it a better carb than the Jikov?

I think you may have Weber 30BDIC (...I have one). It was supplied as a direct after-market replacement of JIKOV carb, especially in the U.K.

There's a skoda parts supplier in Germany called "Skopart" - they have an english website and pricelists/catalogues: www.skopart.de/en/ersatzt eile . They have a very good stock, but on items that are still widely available, their prices tend to be higher than what you would pay here in Czech Republic.



Do you have a spare parts catalogue? There used to be an english version.

thanks,



dragon...



The Weber is just the straight replacement for the Jikov, not some high performance device...



Are you a business? If yes, do you have a website?



Thanks,

Chris

-> Christopher: Use turbo for 135 its better, alumium head and lower compression

-> Christopher: There are several manufacturers of various types of camshafts, which type to use depends on the compression ratio of the engine among other things - others here should be able to recommend a suitable type as well as the manufacturer. Prices range from $120 for re-maschined stock cams to $400 for cams machined from new castings.



Which Weber do you have available?



As for turbo, I doubt there's a "ready made" kit available, but there are several people on this forum who have fitted a turbo (with various degrees of success).



As for parts, I've shipped parts to Skoda fans abroad in the past and see no problem with doing it again 4

Hi,



Thank you.



I do have an extra 1289cc motor from an 89 135GLi - all aluminum but Fuel injected (should be easy to put a carb on it I think...). I think on paper its 58hp VS 54hp with the GLS motor, but it's lighter...



My extra 86 120GLS is however ready to go except for the carb. The previous owner put in sports shocks and springs and rebuilt the entire braking system, and the body is good. The 120GLS motor is good, so I'd like to try it for a bit before an engine swap.



I plan on building the car for TSD rallies here. Speed isn't that important, but snow/mud/ice/gravel traction is (the TSD rallies are mostly in winter up north - logging roads, but lots of hills so more power would be helpful)



I do have a spare Weber for the motor which I'll try to use.



Where can I get a good performance cam?



Is there any affordable Turbo kit for a 120?



There are VERY few spares in Canada. They stopped selling Skodas here in 1989, so no new parts or cars in 25 years. I guess I could buy an e30 325i instead, but being the only guy with a Skoda in 2 decades sounds like more fun.

The best way is to change whole engine

-> Christopher: Hi Chris. There are several options such as engine swap. But as long as you wanna keep original engine, there are some ways too. However you need to purchase some parts from EU, rather say from Czech as old Skoda is not so common car. 120 GLS has a quite high compression ratio already so you can replace camshaft for some sporty one, replace carb for some better one and that’s it. If you have someone skilled (or you are), give him head to enlarge canals in head and put bigger valves. These engines are quite hard to squeeze more HP from them. The easiest option is to replace whole engine by later complete alloy engine with 8 canals in head. There are 10HP more just out of the box and the potential is even bigger. Or you can try to turbo it.

What is the portfolio with spare parts in Canada?

Hi,



I am sure there are many threads on this; could someone let me know some of the best threads for getting a bit more safe hp out of a 120GLS - even 5hp/10hp more would be fantastic. I'd search myself, but it's hard when I don't speak the language.



Thanks
