08 Vector DIES at 5200..!!~..??

[mebelee]

Sat for a few months. Ran well in June. On the stand in the shop ...NO !! we DO NOT have snow either...!!
A little ruff starting. idled well till it got up to temp. Gave it a couple blurps and stalled. No biggie.. Started right back up...slowly engaged & when I went up to 5200. The motor "strained" & shut off. Subsequent tries were the same... shut down at 5200. Any ideas?

Carbs need cleaning

Cleaning....??? Like total disaembly cleaning ...??? or spray #*$&@ down its throat....? Carb removal & pampering is such a PITA on this sled......

Also check the other end (exhaust). Maybe a critter got in there and plugged it up.

Are you trying to rev it up without the airbox intact?

Try revving it up with the choke activated, if it helps, then your pilots are plugged up. You'll likely need to remove the carbs and completely clean them.

Airbox on but wasn't clipped shut and vacuum hose is attached

Those carbs are a BIG PITA. If I can't get it to run with carb cleaner....I'm gonna sell the damn thing !

Airbox must be completely closed and attached.
I take it you made sure there was no mouse nest anywhere in the airbox?

I put fuel shut-offs on the two fuel lines going to the fuel pumps. After the season, I close the valves and run the sled until it dies. No fuel in the carb bowls to evaporate and gum things up. Can be a little challenging to get things going again come the new season, but runs well after getting it going. Your other option is to run it every month with premium non-ethanol gas with fuel stabilizer, until hot and shut her down. Both methods work.

no mouse had to open box to give it a squirt first.
