What year is it? Sound like it runs till it comes out of quick start?
Has it been sitting? If so it may have varnished carbs.
Ck compression.
Ck spark.
Ck for water in fuel.

Crankshaft was swapped ?
Yes CK timing high & low speed
Was fresh gas put in the tank?
CK spark in & out of quick start.
Did you try to set idle mixture screws?

[propman]

freash gas was installed,crankshaft was changed,idle mix screws are set at 6 turns out found them set at 11 turns out i changed it to 9 and it seem to stay running longer cant check timming cus it want run long enought but it seems after 6 sec. it loads up and dies cust wants to set fire to it but i would like to know whats going on

[Michael j]

Have you been able to watch timing light when it dies to CK spark all 6?
Is there no trace of ground on black/yellow under pack with key on?
Un hook shift switch & CK
When it starts it should be in quick start at 1100 RPM

[propman]

i think we might have found it all the fuel rack hoses are coming apart on the in side and might be going flat and shutting off the fuel supply
