flooding issue

Post by Maz » Mon May 14, 2018 2:13 pm



My '75 GL1000 ran OK at speed, but idle was a bit lumpy and acceleration was hesitant. I decided to strip and clean the carbs again. I rebuilt them with Randakks kits and it's been running spot-on, but I suspected some fine rust had got through the filter after de-rusting last year and sure enough, it had. But after careful cleaning, as I was putting the floats back, I noticed what you see in the picture. Two of the other floats are showing signs of surface 'crazing' too. I have replaced all 4 (thanks to John at Wingovations) and she's running great. What D'you all think? Ethanol damage ?

CrapGas would be my first guess.

I've been treating each tank of gas with StaBil Marine.

Haven't seen any issues.

Stablil Marine is the best solution for any storage over three weeks. Good luck getting it all out.

I've used the Lucas fuel stabiliser when I stored it over winter and I try to use the 'Super' grade fuel, which is very low/zero ethanol here in the UK. I guess the damage could have begun before I started using this fuel though. I'll get some Stabil Marine from Ebay and use that in future.
