Sorry for the delay to supply the pressures. The compression on the top cylinder is 105, the bottom cylinder is 110. Also tested the pressure that occurs between the fuel pump outlet and carburetor inlet and it was 1.5 to 1.7 pounds. The motor didn't stop when checking pressure at the fuel pump...
I have ordered a cylinder compression tester and a fuel pump pressure gauge and will update those values next weekend. ---- Correct me I'm wrong but the gasoline vapor you talk about is caused by heat. ---- What would cause that problem in the running motor at trolling speeds? ---- We have tried...
What's the difference between gasoline vapor and air bubbles and the causes. The motor stops running when the gap in the gas occurs.---- Not sure about the usage we purchased it used and it worked okay at first. ---- Haven't done any compression test values. ----- Not sure how to do that or...
How do I check if there is an issue with the crankcase compression pressure on a 1980 Evinrude E10RCSE 2 stroke motor. ----- We have a portable gas tank and we eliminated all the fittings except for the intake cap and hose of the portable gas tank and the primer bulb so I'm not sure where there...
I have a 1980 E10RCSE Evinrude outboard motor that keeps getting air bubbles in the fuel line. Replaced the fuel line with a clear hose so we could see the bubbles. At first we thought they were coming from the tank so we eliminated all the connections all the way from the tank straight to the...
