Well, this has really got me stumped. Now, I can't even get my 1500 Midg=
to start up, let alone run proper.
I was making a trip to the big city and had gone about 10 or 15 miles whe=
the engine missed a couple of times . I turned round and headed back hom=
After stopping at the grocery store, I then had a terrible time getting=
the thing started again. Anyway I made it back home but going about 50 m=
because the engine wouldn't rev over about 3000 rpm.
Back home, I replaced the (mechanical) fuel pump and she fired right up. =
drove down the road about half a mile and, going round a corner, she
totally quit. So there I am, with no top and the hood up and it starts t=
rain and the neighbours driving past. Well, I disconnected the fuel line=
at the carb and cranked it. Sure enough, there was fuel coming out. =
Unfortunately, the car did not burst into flames. Reconnected everything=
and it fired right up and I got back home before it quit in the garage.
Well, I've taken the ZS carb apart and checked the float level. The floa=
also floated in a can of fuel after been weighted down for about an hour.=
The needle valve isn't sticking and everything looks OK. The manifolds a=
not cracked and they are securely mounted to the engine.
I swapped the plugs, checked the resistance of the plug wires, and at lea=
two of the plugs spark when the engine is cranked. Its got an Ignitor se=
up (unkown age) with a relatively new rotor.
Anyway sometimes it runs for about a second or so, other times it doesn't=
catch at all. I checked the pump again and it seems to be working fine =
pumping a decent quantity of fuel in a can.
I'm afraid to take a compression reading on the cylinders because if ther=
is anything mechanically wrong, out comes the humungous sledge hammer. =
(This is the engine that I spent several days in Purgatory with, changing=
the big end bearings from under the car) =
Any ideas. Thanks, as always, Adrian
