So that's why my lawn mower has been running rough lately. The carburator is getting old and must have somehow clogged the fuel injectors!!! Why didn't anyone tell me that before?
Update - Brake pad oil pump rebuild is a success! Only took about 2 hours to do, it is definitely a DIY job. Only problem is that while I was down there, I noticed that some moron decided to make the brake lines coming out of the caliper out of flexible rubber!! What on earth is the logic behind this? No big deal, I just replaced them with the rigid steel lines, but I had to run back out to the parts store to get new ones. Also, I didn't feel like reattaching the brake lines before I went (what a PITA it is), so whenever I needed to stop, i just opened the door and stuck my foot out.
While working on the catalytic converter, I noticed that the catalytic converter lead injection pump was getting weak. I guess its time for a new one.



I hope the engine does not have to come off for this job, as it would be a real PITA to drive back to Pep Boys without the engine, acceleration would seem sluggish, don't you think?
