We all have some frustration with small gasoline engines from time to time. Often, do to our own weak maintenance schedule we put these engines away for the season without paying any attention to the recommended procedures in the owner manual. Today I am going to talk you through the steps to adjust a small gas engine's carburetor.
1. Read through the whole list before you start adjusting. 2. Close both jets GENTLY 3. Open the Low speed 1/4 turn 4. Open high speed jet 1 1/4 turn5. Start engine. 6. Adjust low speed until idling smoothly. 7. Open her up wide open. 8. Adjust High speed until engine transitions smoothly from idle to high speed without bogging. 9. Shut engine off. Let it cool. 10. Once engine is cold. Fire it up and let it idle for 30 seconds. Open it up wide open again. Adjust if necessary.
Please Note - It is best to adjust the carburetor at the beginning of the usage season. In other words, don't adjust your rototiller engine in the dead of winter when you won't use it in those conditions. Regards, Joe
your idler jetsa are blocked ,on this carb their should be an air screw as well so it might not be set right ,this air screw should be about 1-1/4 to 1-1/2 a turn out as a rough guide .Now another favourite trick of mine is to open the drain screw on the bottom of the carb then pull the feed pipe off the tank from the fuel shut off and fill the carb with brake and clutch cleaner ,spraw it down the pipe and leave overnight ,this will hopefully unblock any very small jets within the carb body ,Yes i know its a bodge and its not the correct way but it does work on old engine with carbs like my aux outboard or my motor bike .
Hello Randy. I can talk you through making adjustments to your Jiffy ice auger engine.
1. Read through the whole list before you start adjusting. 2. Close both jets GENTLY 3. Open the Low speed 1/4 turn 4. Open high speed jet 1 1/4 turn5. Start engine. 6. Adjust low speed until idling smoothly. 7. Open her up wide open. 8. Adjust High speed until engine transitions smoothly from idle to high speed without bogging. 9. Shut engine off. Let it cool. 10. Once engine is cold. Fire it up and let it idle for 30 secs. Open it up wide open again. Adjust if necassary.
NOTE 1: The trick with the Jiffy's is to tune them during cold (ice fishing) weather. NOTE 2: Low speed screw,the one on the left. NOTE 3: High speed on the right. Good luck ice fishing! Regards, Joe
it sounds like your lower unit pump is going out
hook it to a fresh water hose and run the engine and see if more water comes out of the exaust if it is more then i would replace the lower unit pump check and see if the screens on the lower unit are plug up with seaweed and clean them that would restric the flow of water
try disconnecting the throttle cable, loosen carb linkages, assure that both carbs are FULL closed....tighten linkage - and cable ...check for FULL open and close with the throttle....this will be your starting point, advise to get a service manual for your outboard model to correctly adjust the carbs for max performance....GL hope this helps..
the inside of the prop has a rubber between the prop itself and the inside splines to act as a shock absorber,say if you were to hit a rock. that rubber had spun out and the splines are turning inside the prop. the prop is screwed. seen it 100 times before.
