Customer Question
I have vanguard 6hp...

I have vanguard 6hp which drives a mulcher unit. Have not used for couple years, stored under tarp in closed garage. Cannot get to fire. Tested for spark ok, drained and replaced new fuel, spark plug is clean and good condition, unit bought new and only lightly used.. any suggestions please?

Mechanic's Assistant: Did you double-check the thermostat? And what about the unit's filters?

Filters air, fuel clean and good condition. Unit has not been disassembled or tampered with. What do I do to check thermostat. Thanks

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes as I am reasonably able to follow sensible instructions or look up info for troubleshooting but not experienced technically.

Mechanic's Assistant: Anything else we should know to help you best?

I have tried with returning to retry after switching off switch and choke then retrying later but no response re firing of engine.

Remove the spark plug and put a teaspoon of fuel directly into the spark plug hole re-install the spark plug and see if it will fire. If it does, the carburetor needs to be cleaned and rebuilt. If it does NOT fire, check the compression, needs to be around 80 psi. If compression is low, it is not going to start. The rings or valves are leaking.

Good. I filled fuel tank , then 2 times poured small amount fuel into spark plug hole, refitted and cranked engine. On both times engine fixed and started but for only few seconds. Sounded quite ok but makes me think that fuel is not getting through to chamber?.
