Uneven engine operation.

[Jimarilo]

My recent 940s 1995 purchase runs like this ......lumpy on warm tick over. Cold and hot start works perfectly

I changed the fuel filter and clogged air filter but still lumpy

Will investigate further after I change the cam belt

Is the crank bolt 27mm and the torque setting 300 lbs ??

I don't have the tool for locking the crank pulley, but will figure something out. Also need to find a bigger torque wrench lol
