So we have a 1949 3600 with the 235 its been sitting for about 5 years though it did get drove a bit in 2016 for a mile. We finally bought new exhaust for it so we drove it into the shed under its own power. Then the next day we had to move it so no problem again drove out and back in. Then 2 days later we had everything done and working brakes exhaust etc. We went to pull it out and all of the sudden it would not move after a bit of fiddling we got it to back out but it then would not go forward. So we pulled the service cover off under the clutch and found a mouse nest we blew it out and the clutch peddle felt much better. But it still barley moves and slips really bad it wont slip as bad in reverse it actually stops slipping at times but in 1st it slips hard we drove it like that for a bit to never smelled burning clutch. Do any of you have an idea to what is going on?
