That way the hex bar would have been parallel to the fan shroud.

How does it run?

It runs well. I cant compare it first hand to the carbs that come with the WW kit as I never installed those. I have put on a few thousand miles with no problems.

You are right about the linkage. I used it at the time because I had it laying around, but I now have the csp linkage although I still need to install it.

I will say I am glad I used the dellortos because tuning has not been an issue at all and I have read about some people having issues with the WW carbs.

Is that the pull/push CSP linkage? That'll look good.

anyone who drove with DCNF webers? I love them because they are compact, but don't know how streetable they are and how easy to adjust

Mon Sep 12, 2016 5:06 pm

yes streetable and yes easy to tune.

Finally have my engine stripped down and will be doing the head swap this coming weekend. Hope to be running in two weeks...will be doing a few cosmetic items while the engine is out.

Definitely hoping for a noticeable increase

Crappy IPhone picture, but the head swap is complete. Just waiting on a fuel line fitting to finish. I had to trim the hell out of the cylinder head tins. Glad I bought another set so that I didn't have to cut up my original 54 tins.

Hopefully the fitting shows up early next week so that I can crank it up.

Good to see it coming together (making better progress than me!).

Will the shroud fit with the engine in the car? Is your decklid removed?

Thanks

Richard,

Yes, I never install an engine with the shroud on. It's already tight enough for that, and it would be a major pain to guide the engine in. I know people do it all the time, but not me. My deck lid has quick disconnects at the hinges...removing it is a piece of cake.

Look at the pic again, yes the deck lid off, look at the brackets. Today I finished installing the shroud and other electrical items. Replaced the oil and filter...just need that dang fitting now.

Yes...can see now. I was originally looking on my phone and missed that.
Thanks
Richard

:shock: Bad news! The damn drivers side carb body is cracked at the fuel inlet (barbed fitting). Hard to see until the fuel flows thru it.

I've contacted the seller and hoping for good news. It's definitely a risk with used carbs...

Bummer, do you just need a new carb top?

Tue Nov 22, 2016 5:32 am

Yes, but finding a 36IDF top may not be easy.

How does yours run? Looks awesome

New carb top is on the way...hopefully will have it running very soon

I got the carb fixed, reinstalled and the carbs are synced. Beautiful and smooth idle.

Now the next hurdle...the dang linkage. I went with a CB Hex bar for straight manifolds. Two issues, the hex bar was way to wide/long and it mounts way to high causing the throttle cable connection to be less than ideal.

I had shorten the hex bar over 2.5", and then drill it out

Now I need to take hex bar mounts off and drill/tap new holes lower, to properly align the throttle cable/connector.

Gotta love custom installs! Love the results so far, just taking more time

Fri Dec 23, 2016 1:10 pm

Updated picture...just waiting on a part to complete the hex bar.

Looking good! Ready in time for Christmas?!

I wish! Unfortunately here in the states, most hardware stores do not carry a lot of metric hardware. I'm waiting on a 8mmx1.25 thread coupler to finish the linkage.

I'm sure it will be here sometime next week. The carbs are tuned and ready to go...

For anyone considering Okrasa heads, you really need to get a set of the Speedwell Manifolds.

The engine runs so much better with the dual 36IDFs. It revs extremely fast...instant power.

Tuning has been okay and I'm a first time dual IDF user. The biggest issue is the room to adjust the idle mixture screws. On the old Italian 36's the idle mixture screw is recessed/shrouded so you cannot see it. Adjusting it is a major pain. If I could go back, I would buy a new pair of 40IDFs.

I'm running 27mm vents, 110 main jets, 180 air jets, 50 idle jets, 40 pump jets, and F11 tubes

Linkage was the biggest pain. I had to make several adjustments to the CB Performance hex bar system to make it fit correctly. I would recommend using the WW bolt on push/pull system.

Here's a shot of the 25hp Okrasa I built for this car when I had it.
1511cc, Okrasa heads, Speedwell goodies inside and out with P-11's

It run great!

Sold the car before I got a chance to install the engine. It's currently sitting on an engine stand in the back of my shop next to a Barndoor 36hp that I plan on mashing together with it to make a 36hp Barndoor (Case) Okrasa
