if the blade is still able to spin around alright than you have to take the blade off and then attach what was spinning the blade and attach it to the tire somehow so that it spins the bike tire instead of the blade.
Sorry, but engine connection cannot be defined without make and model of engine and tiller.
no a lawnmower engine is too big try a weedwaker engine
Yes , you need a gear box to make it work.
take the muffler off
At a dealer of the engine brand or possibly at a mower junkyard. If going for the latter, make sure it is not bent.
That depends on the model/make of lawnmower, but it will always be on top.
Depends on the type and make of engine, your expertise and the tools available. I could totally dismantle and rebuild a lawnmower engine in a day, - a Chevy 350 took me a little longer.
The correct gap for the spark plug of a Briggs and Stratton 6.75 Lawnmower engine 0.030. Most new plugs come with that gap, but it is best to check to make sure.
My 6.75hp Briggs calls for 30wt, so I would make a reasonable assumption that the 6.5hp calls for the same.
What engine are you referring to here? Are you referring to an engine from a small "tool" like a chainsaw or a lawnmower? Or are you referring to an engine from a vehicle? Also, what type of engine are you talking about, like model, make, etc? Please be more specific in what you are asking so you can get a more proper answer.
Removing the governor. The governor serves two purposes on an engine; it limits it's top speed to protect the engine and it helps to provide constant output power. By removing the governor you can damage your engine. Turn It off and put it in a wagon and run with it.
