Filthy fuel filter

Post by Crowther » Sat Jul 14, 2018 7:30 pm

The Scim wouldn't start today. Cranks OK and I've checked the ignition. I took the top off the fuel pump to inspect the filter and it was full of crap - tank was changed recently. All the rust and debris was on the tank side of the filter but now I'm concerned some of it might have found its way into the carb. Any tips on where to start?

Take the top off the carb and check the float bowl.

Have a look at the filter in the carb - if it has one its in the middle of the two pipes.

I removed the carb filter - mucky but not completely clogged. Cleaned it and refitted and after a good crank he started. Unfortunately he bogs under a bit of throttle.
Last time I drove him was 10 days ago and he ran well. I think he might be trying to wriggle out of going to Silverstone...

Started OK today and a few squirts of carb cleaner past the chokes and a bit of revving and he's back to his old self. I suspect I'll be cleaning these filters frequently until all the crap has been flushed through. I see that you can get replacement filter inserts for the Weber carbs. I wonder if they available for QH fuel pumps...
