Poor Running Series IIa

[tony]

Check your carbs internal seals , especialy the rubber parts , I have seen those deteriorate when a carb has been sitting far too long without gas in it , they tend to dry out .

Series IIa, 88inch, 1964, 2.25 petrol, 36K miles. My rover had been sitting for at least 12 years. I got it running this year (nothing done to the engine). The first 200-300 miles it seemed to run good. Then it started losing power intermittently (every 10-15 seconds). At slow speeds it felt like it was lurching-high speeds the momentum eased this feeling. During this time it never died. I turned the mixture screw on the carb and it started running better (w/o the power loss). Consequently it was smoking pretty bad (it would gag me at a stop light) and smelling pungantly like fuel. The other day after driving 20 miles it wouldn't start. It sat hours then started again. A complete tune-up will come paycheck to paycheck. Any ideas on where to start? Thanks

I had a similar problem on my IIA. It had sat for 18 yrs. I removed the plug at the bottom of the fuel tank, and the fuel outlet port & sender from the top, and blasted all the crap (lots of it) out of the tank with a garden hose and spray nozzle. I've been driving it another 12 yrs without another similar problem. This might be worth a try on yours. Harv
