Can they fit in my engine ?

The last number is the size of the secondary venturi.

The picture you posted is too small to see, so I'm not sure what you are showing us... but either carb will run your engine, but I'm not 100% sure what you have from the factory.


If you look inside your carb, the venturi should have a number on it.

oops i misread the post

On that website, there are 2 carbs for the 787 engine. the BN40i-38-26 and the BN40i-38-27. The first is for the Mag side, the second is for the PTO side. You would need one of each

Where do you see BN40i-38-30? Its not on that website?

thats crazy. Buy a set of 40I carbs from ebay, for 100-200 buks, and be done.

Maybe they're overcharging because of his location?
(his info says he lives in Bahrain by Saudi Arabia)

Because when I go to the website that you did a PrintScreen of, it says that the carbs are $230 each. So you would be paying $460 total to replace both carbs.

Maybe you are saying that you want to replace the carbs on both engines, which would be $920 plus shipping....

Why are you replacing the carbs? Did you try rebuilding your current ones? (Rebuild kits are about 50 each)

I don't understand... the company's website says that the 40i-38-27 is $230 but when you called they said the BN40i-38-30 is going to cost $485?

replacing the jets is cake

you take 4 screws off to remove the cover, remove the regulator block (2 more screws), then just unscrew the jets

look at the mikuni manual for a detailed description and pics... or theres a thread on here somewhere with a PDF for cleaning carbs that would show you

Those prices are jacked. I would try to find someone to buy them frrm on ebay who will ship internationally.

If someone is trying to charge you a crazy shipping price they are nuts. They will easily fit in the large USPS priority flat rate box, international postage to you in that box is $53.00 and that is priority mail....im sure they can be shipped cheaper.

I found it on Atlantic's site for 199 each. That is crazy if the price is double for you. I dont get it. I will PM you an idea.

I have a 98 SPX with Mikuni Carbs, but not sure which model 40i, 38 or 30.... How do I determine this? Or is the 38 standard from the factory?

Thanks,

You have an 800cc motor, which has the 40I carbs. All 787/800cc motors, have the 40I carbs.
