36hp engine with WW Okrasa running rich

[jurgen272]

I have a 36hp engine with WW Okrasa kit and camshaft, everything else is stock
With the standard jets in the replica Solex's the engine is running rich. (Idle screw is turned in completely, ...)
Any advice on which jets I should change/use (at sea level)?

the jetting should be fine. i would check the float level. maybe loose or bad float valve? those things are made in india after all and have some bugs in them sometimes. luckily standard solex parts work in them. or high fuel pressure will cause that.

Hi,

don't have experience with the WW Okrasa kit, but I guess they tried to copy the original Okrasa jet sizes?

there you can see some sizes, but they should be the same that you're running. When I rebuilt my original Solex carbs and bought new gaskets, there was the choice between a Solex 1.5 and 2.0 jet, I choosed the smaller one as it was installed before...

it is not a jet problem. i have built them with no problem. high fuel pressure or bad float valves. the jets they come with are fine.

Too much fuel pressure. correct 2.5 -3.5 psi. I just bought the Wolfsburg West 36 hp fuel pump rebuild kit and the spring was much stronger and even longer. I didn't even use the spring in the kit. Ended up using the OG spring and the diaphragm from the kit.

I don't know whether you bought that fuel pump kit. Just assuming since your Okrasa kit came from them.

I agree with most here. Many people don't realize how much float level effects mixture. The float bowl is not simply a place where fuel sets before entering the engine. the level of the float effects ts the level of fuel in all the internal passage ways of the carburetor and in some cases emulsion tube level. This effects how easily fuel mixes with air as it passes thru the carburetor.

Too high of a setting on fuel pressure will also overwhelm the float and cause mixture issues as stated by others here. If you are having fuel in oil you have a very big issue with mixture or unburnt fuel in the system. Also, pierced fuel pump diaphragm can cause oil in fuel. Good luck, proceed with care
