Looper jets

[Captain75]

Hello!
Is there anyone on this board who are interested in selling OMC Looper main jets?
Unfortunately for me, dealers in the US don’t sell OEM outside the country.

I’m in need of two sets (v6):
77D and
78D

Might be done with a reamer!?

Are there no dealers in Sweden or elsewhere in The EU ?
OMC used to have a big facility in Belgium for the European market.

They don’t make them that small I use a pin drill for air bleeds now I only use idle adjusting throttle body but still drill main jets a good Titanium drill bit set that has a number set with the decimal equivalent that works fine in a pin drill holder

Got a hold of the BRP general agent over here. Unfortunately, they told me the jets I’m searching for (75, 76, 77 and 78Ds) all have expired and they can’t deliver any of them.
Due to this I will have to try another angle of attack...
Today I recieved these beautiful german-made reamers from a UK hardware store, I hope they will meat my expectations when it comes to enlargening needle seats and high speed jets.
My plan is to start with .075 reamed jets in all cyls apart from #2 which will have .076”. Hopefully these will give me some more top end revs. Currently running jets drilled to appx .081.
Motor is a closed deck Evinrude looper with 2.7heads, and mid bore carbs.

Thanks for sharing. I need to get a set of those. Likely cheaper then ordering 4-6 X's how many different jets to find out what you need. And then when you order them, it takes time for shipping as no one has them locally.

I have drilled jets before. An old Harley with a carb that no one carries jets for anymore. But, after a little looking into it, it turns out that Yamaha still used a carb with similar jets not to long ago and a local dealer still carried them. Even though they fit the carb, they were not right as I was looking to feed 1200+ cc's from one jet where they were feeding 300cc per jet. Just could never get it right, but still runs good. I just want perfection.
