Strombergs flooding
Posted: Fri Jun 10, 2005 2:49 pm
This is my first post, having (after 30+ years) finally succumbed to Lotus disease. Like Stuart, I just acquired a 72 Elan Sprint dhc. A blast!
I've been following this forum with great interest, and hope someone may have a suggestion regarding the following.
Car had been running a bit rich, but basically fine. Then, abruptly, it wouldn't start. Flooded. At first, only when hot, now all the time.
Will not start at all. Raw fuel drips from airbox. Pull off airbox, both carbs wet. Crank over and fuel spurts from the hole above and to the left of the throat of both carburetors. Not good.
Seems like needle/float problem, so...take apart both carbs. Clean, no gunk, corrosion or grit. Floats look fine. Loose rivet on one, where the metal arm attaches to the plastic--no leak, and seemingly not a big deal, but fixed that. Replace both needle valves, reset float height at 17mm, replace both diaphragms (why not...?), put all back together, and...
...same problem. And it affects both carbs.
I'm not finding anything in Haynes, and now that I've had the carbs apart I really can't see what (besides needle/float) could be at fault.
Any words of wisdom for a newbie?
