  • / Backfireing, cutting out while blade is engaged - 28" hivac
Typing this for my dad as we speak:

"As soon as you engage the blade it starts to backfire and missfire. But once you put it down to lower idle, (turtle) it runs fine...even with the blade engaged...once you give it throttle, it cuts out and backfires (loud pops)"

Is there a repair or trouble shooting manual available?

All the dealers want us to bring it in and won't help us one bit.

We had a fairly bent and cracked stock blade on it, and I believe that is when the problems started. We have replaced the blade though with a brand new one.

Rats had made a nest inside but we cleaned all that out and checked all the wires we could.

I noticed the seat switch is a bit loose - is that a common problem? How would I bypass it manually?
