Well after 2 years gathering all the parts to rebuild another BRAT

 

4" Lift on a 1978 Brat...ca smog:dead:

timing IS set to 8 degrees....but seems to BoUnCe (tried 4,6,10,12)

rebuilt ea-71 "All" new exhaust, cat.... with New "POINTS",cap and rotor (points set at .018 gap) rebuilt hitachi carb, new wires, plugs

 

 

 

in the driveway: it Idles "FINE" but it backfires thru carb when throttle is hit (under 2500 rpm)seems to rev high ok

 

when driving: Throttle needs to be feathered to help built High rpm's but still has no power

 

 

 

Any Ideas? Starting Places?

 

Thanks:burnout:

How old is the gas? I've seen 2 year old gas act like what you're describing.

Vacuum advance working? That could cause similar symtoms.

New gas..

 

I'll be checking vacuum today

 

Thanks

I had a 78 sta wag and the only way I could get it to run properly was to set the points with a dwell meter. When I used the dwell it ran great.
