I picked up a '90 BII last night. So, any second thoughts I had are too late.
The previous owner had it on a deer lease for about a year before overheating it. He put new heads, radiator, and T-stat in it but left it sitting for a year after that, so I do have some issues.
When cold it takes a couple of attempts to get it stay lit. It used to idle down to 800 like it's supposed to, but I had a backfire in the throttle body from carb and choke cleaner and now only works down to 1K rpm. It vibrates awful at idle, smells like it's running rich, blows white smoke, and when the rpm's are bottomed out, tap the throttle and it stutters, stumbles for a split second then revs. I have replaced the air filter, tried to clean the throttle body and replaced the IAC. All of these were in severe poor condition. The throttle body and IAC were badly caked in oil deposits.
Anyone have ideas for these issues? I am wondering if the timing is off, but I am going to go through the typical tune-up points first. I'll see what happens.
