86 or 92 Mercury 9.9 Cold Start Problems

Not hard on the engine to do this. The engine leans out as the fuel level in the fuel bowl drops.

Does the fuel pump supply fuel to the carburetor throughout the RPM range? If so, leave it alone. The diaphragm in a fuel pump is not a valve! The diaphragm is the "pump" that oscillates back and forth with the positive and negative pulses provided by the crankcase. There are small umbrella valves ...

Has to be set with a timing light at WOT full advance. NOT on a hose! Timing specs may be on a sticker on your engine or available from a service manual.

Nope....fuel lines cannot siphon a fuel bowl dry. Yes, a primer bulb has a check valve in it. You should be able to blow through from the inlet to the outlet. That is how the primer bulb is able to fill the fuel bowl. What you have to remember here is that the engine does not need a fuel pump at al...

86 or 92 Mercury 9.9 Cold Start Problems

Curious as to why you would think an air bubble has anything to do with this?? First off. Do you have a choke on the engine or a primer system? This has to be answered. An owner manual should tell you this or you may find it in a parts diagram. Makes a difference in starting technique but we will c...

old mixed gas

Correct...... YOU CANNOT BRING BACK OLD GAS BY POURING STABILIZER IN IT...............PERIOD! Do not worry about the few gallons of gas left in the tank when you have a valuable piece of machinery you are about to subject that fuel to that you can very likely damage as a result. KMixon - also corre...

If the low speed needle is backed out (counter clockwise) It will richen the engine. The engine will not sneeze if it is being richened. Recommended starting point for a low speed needle is 1.5 turns from a lightly closed position anyway. Richen your mixture and tell us what the engine does. You sh...

1968 EVINRUDE FASTWIN 18HP - COLD START PROBLEMS

Your answer above was vague at best. The small square pumps are barely adequate and do not handle the fuel lifting duties very well. Much prefer the larger domed pumps. Still, if you are pumping the bulb then you are effectively taking the place of the fuel pump and the carb bowl should fill and be...

OKay check and see that the high speed nozzle gasket is in place. If not you will have no suction to pull fuel through it for the idle circuit. Packing washers should be in the idle needle and seated. Brass pick up tubes cracked? Richen the idle needle from whatever position it is currently in. Go ...

Who's tune-up kit did you use? What all was installed? On the carb does the choke blade close FULLY? You mentioned you had to manually place fuel into the cylinders to get it to fire. Who's carb kit was used ? Did you pull the aluminum plug on top of the carb that cover the idle calibration holes? ...

Need lower unit for Johnson 48 SPL (1993 model)

That is not a normal failure scenario for those units. That failure shows what looks like a clutch dog that came apart and went through the side of the housing.

We saw failures for a while on the impellers but that issue seems to have gone away. Talk to your local dealer as well and verify or see what they say about it. Was a known issue and usually it doesn't take long to identify and rectify the issue but longer to rid the existing inventory and get exis...
