Linkert carb conversion

[Emerica1975]

Awhile back I found a cylinder with a linkert intake already installed on it for sale on eBay. I finally got it mounted onto the engine and a carb hooked up and I’m having trouble with the gas leaking. I’ve adjusted the float and tried the float level at 1/4 inch and also 5/16 inch for float height. I’m wondering if the angle the carb sits is just too steep. I really should have figured this out prior to having the cylinder honed and worked on. I know I’ve seen other bikes with this conversion and there carbs were a lot more flat with how they sat in regards to the engine. I just assumed when I bought this with the linkert intake already on it that it had run like that in its previous life. ( you know what they say about assuming!!!). Anyway if anyone knows if this looks way to steep an angle for the carb to work I’d love to know so I can figure out what to do next.

The gas is leaking out of the backside of the carb where the float bowl mates to the carb. Right by the throttle bushing.

yep. it needs to be parallel to the ground. It will overflow until ya straighten it out.

what cylinder do people usually use to convert to a linkert carb. Because I don’t think it’ll be possible to adjust the intake to make the carb level without the bowl nut hitting the engine. I wonder if other cylinders have the intake manifold going in higher up.

It looks like a curved adapter will re-position the float bowl but something fancy will have to be done to accommodate an air cleaner.

If anyone has a picture of a 165st engine with a linkert m series carb on it I’d love to see them. Thanks!

Does your bowl nut still have a hreaded stud on the end?

[Emerica1975]

I had an old bowl nut that I cut the stud off of this afternoon. Now I’m cutting the intake pipe to put a down ward angle on it. Your carb looks perfect on your bike I’ll be happy if I can get mine even close to how you did it. How come your cases don’t have the extra casting for the finned carb covers? Did you grind them off?

[Mutt]

yep, I ground them off and ploished the cases
