I have a 9.9 2 stroke. My motor starts first pull but won’t idle very long. I have to keep it in fast so the motor doesn’t shut off. If I go too slow the motor shuts. Do you think I need a carb clean or is it likely something else?

The carburetor need to be cleaned and new repair kit need to be installed.

Great video! This channel is great!! Quick question and help?? Hey team We have a 1977 Johnson 9.9. We loose power/engine speed under load. When running via the ear muffs we get high revs, but when in the water we get no decent boat speed and less revs. We have brand new fuel lines, fuel pump replacement kit installed, strong spark, new spark plugs, holds pressure at 105 in each spark plug, carby has been been repaired, float looks good and all clean. Previous owner has added an extra rubber ‘ring’ to the roller on the cam follower - which make the throttle open before it gets to the marker on the throttle control cam. Could this interrupt the ignition timing enough to cause loss of power under load? We are using premium (98) gasoline with 50:1 ratio to oil TCW3. Should we use something lower like 91? Also the tank we are running has a small amount of 2stroke engine cleaner, could that be it? (Going to try fresh petrol this weekend with out cleaner). Could we have missed anything with the carb? Should we remove and replace the top plug and air bleed nozzle - even if they look fine? What other air tests can we perform on the carbie to make sure it’s 100% Thanks in advance for any advice!! Cheers

You can do a test without the engine hood.If the engine increases the power you may have to modify the hood

[@Jason-xw1fm]

We have followed your advice and put holes in the hood, and we run the motor without the hood. Could the spark or carb butterfly impact?
