Title: Old fuel, gummed carbs etc
Post by: Bixxer Bob on December 18, 2012, 10:12:26 AM
Started work on the Guzzi Le Mans Mk1 yesterday.  It's been standing with old fuel in the tank and carbs for at least three years.  The old battery, the size of one from a small car (Guzzi obviously weren't taking any chances) was knackered so fitted a new one.  Opened the fuel tap, lifted the choke levers (one on each carb) hit the starter, three cranks and up she fired!!  Afte just a little coaxing with the throttle, she picked up, cleared her lungs and roared.  A lot of brown smoke to start with but she soon cleared out and runs nicely.  So much for old fuel woes,  you can't beat tractor engineering!! :hat10

Charging circuit is knackered though, need to start fault-finding....

Just wondering if you followed the advice in your recent post and fitted a Motobatt?

Nah,  as I said at the start, it's the size of the battery in a small car, dimension-wise anyway.  It's 26 AH and I  found one at the lawnmower shop for £37.  Bargain!!

There was a fantastic article in Feb 2011 CMM, about a guy who has had a Mk1 from almost new and has modded it with allsorts of stuff. Ive still got a copy if you want me to scan it for you John.

So I'm told..we can blame supermarket chains for the reduction in petrol quality. They put pressure on manufacturers to reduce price..hence omission of additives etc

Not really, I think you can blame our lords and masters, they were the tits who decided to make fuel go further and give it a spurious green credential by adding ethanol.
