So I finally got Roxanne out of the shop today, and lo and behold, she runs like crap. No power, and backfires on shifts when accelarating hard. Also, it just runs pretty rough.

 

The theory that I like the most is that in my haste I got the timing on one or both of the cams off by a tooth or so. I remember the mark almost lining up but not quite. Maybe I switched the two crank pulleys and that messed it up (as far as I can tell, they are slightly different). Does this sound reasonable? I can think of no other explaination for this.

 

Please help!

I wouldn't imagine that the crank pullies would make a difference in the way it runs.. getting the belts a tooth off would sure do what you are describing..

Thanks Caleb!

 

I think I'll go take off the t-belt covers later tonight and check that. I REALLY hope this is the problem, because I would hate to have to tear down this engine again and spend even more money on it (about $1400 invested in rebuild).
