On my 1856 (tube frame with 18hp briggs twin conversion) it seems that I have a bad spot on the starter or it is simply worn out. I put in a new starter when I built the tractor 5 years ago. At the time I could not find an OEM starter so I put in a cheap after market from ebay. I put a new battery in it this week.
I went out to the shed on Sunday to run it. It started up but I had to tap on the starter to get it to move. I drove it over to the garage and shut it down. 30 minutes later I go to start it and even with a jump starter pack on it the starter will not even move the engine through the compression stage. The starter got very hot while trying so I gave up. I towed it out to the shed and an hour later I hit the key and it turned right over.
I'm thinking that maybe it has a bad spot in the starter, it's worn out or possibly there is a compression release on this engine and it is not always working right. It's a briggs twin L head 422437-1209 engine. I found an OEM briggs starter on line that I'm thinking of getting in hopes that it solves the problems.
Has anyone experienced a starter that would turn so slow it would not turn the engine past compression stroke? I'm hoping the starter is the issue here. This is a picture of the tractor and the engine.
