My mower seems to have low fuel pressure. Gas filter is new, lines are clear but sometimes the engine starves for fuel. The filter has almost no gas showing in the clear globe when running. Is the black...


Yes it is a vacuum fuel pump. Remove the line to the carburetor and place a clear container to catch fuel. Crank the engine and watch to see how much fuel is being pumped. It could either be a weak fuel pump or the pickup line in the fuel tank is starting to rot, depends on how old the mower is. The pickup line in the fuel tank is rubber, and sitting in fuel for many years can break the line down causing it to fall apart. It should be noticeable more if the fuel tank is below 1/2 tank. Hope this helps, Daniel.

Runs good until you accelerate then it lacks power it dont miss just alarge power loss in every gear if you let off of the gas its power comes back its about to drive me crazy please help? dwb


I would suggest changing the fuel filter. The engine seems to be starving for fuel and if the filter is pulgged, the engine will bog down under load. Then the engine will run better when coasting because the fuel pressure will build up again.

1973 Corniche engine shut down


I sounds like a fuel delivery problem, I would first check the filter -above the rear axle- if it's clear, test the fuel pump delivery. ps; the original filter elements are hard to get, we usually fit a good in line unit instead, leaving the original filter housing in situ. Also, unless they are fairly new now is the time to replace the fuel hoses back there.
