T1760 problems

[Morganfd9]

Bought a 1997 model t1760 , seller said it wouldn't stay running over a few minutes.

Would start , run fine for 5 minutes or so and then shutoff.
Replaced carburator with a complete new one,$239!
Same as before!

Could this be an electrical problem?

Coil maybe ?

Air filter is like new, and fuel delivery is correct. Dunno what else to check.

buy a cheap in line spark plug tester & a can of starer fluid.
Hook up the plug tester and watch to see if the flashing tube stops flashing before the engine stops.
If it does not stop flashing till the engine is almost stopped then you have a fuel system problem.
If it stops flashing with the engine running at full throttle then you have an ignition problem.
So for $ 5 you have halved the work in diagnosing the problem.

If it keeps flashing while the engine is slowing down spray a little starter fluid into the carby, NOTE I SAID A LITTLE and for safety sake from full arms reach, just in case it backfires.
If you can keep the engine running with little short burst of starter fluid then it is not getting enough fuel so the prime suspect will be the fuel line, tap ( if fitted ) , filter & pump as you have just put on a new carb.
