OKay- 70' 1.8L, with dueling Dellorto's 40mm.
Car runs sweeeet, perfect. Then starts running crappy. Hmph, thinks I. (IMG:style_emoticons/default/wacko.gif) Pointless ign, I check the rotor anyhow, and swap it. Test Drive, LOTS of pinging, and at 1/3 throttle or less the car just LUGS does not even try to accelerate below 2500RPM. get the RPM's up and it starts pulling. Smells funny.. ..weird oilt smell. ..not burning. Just oily. Any guesses.. .? Not *quite* sure I understand it yet. But I found what seemed to be the problem. -Bob O |

Sounds a lot like sticking mechanical advance. That would explain why it runs great above 2500 rpm. Maybe only sticking after it gets warmed up? I had my advance jam up (c-clip holding dizzy shaft together came off) and this is exactly what it did. Full advance all the time. Below 2500 it would buck and knock, smoke and smell bad. At 2500 rpm it took off like a rocket (well, the 1.7 liter version of a rocket, which would be an Estes A or B size rocket).
