looking around these twins all have some kind of starting issue and need a big battery gonna try the 2 battery trick to see if that will do it

Nice mower, and no they don't, use a good battery to crank it.

The 16.5HP Twin on my tractor cranks a lot easier than the old 14.5HP single I/C did on my old tractor.

And mind you it's not the size if the batteries that matter like Amp, but rather the CCA of the battery.

How much juice it will give you at 0F for 30seconds.

Yup

Always best to get the biggest Cold cranking amp capacity you can, especially in a colder climate.

ive got the battery on charge its deff to small its a 230cca gonna have to look into something different

well ive got it to run a little and i ended up dooing a pull start starter combo to doso im gonna need to clean the carb and prob rebuild the pump

drove it around today cleaned out the carb

those opposed twins usually have a hard time starting with any thing less than 350amps. if that doesn't work than its the starter. mine had the same problem, even tried jump starting it off a truck with 2 800amp batteries, so I got a new starter from choo choo's for 90$. works great now.

It might be your starter.

i found starters for it on ebay for 35 shipped trying to rule out everything else and then the starter getting a battery in the next couple days hers a vid of me pull starting it [url=https://www.youtube.com/watch?v=GlVsRcJgzM4]https://www.youtube.com/watch?v=GlVsRcJgzM4[/url]

its probably the starter. i had the smae problem with and old twin i had
