Hello to you all, since im new to this forum and does anyone have good ideas how to clean up old carbs? I know there are certain chemicals designed for the job, but im more of after home made recipies since i live in Finland and ordering chemicals from US is limited to sea freight. The thing is that i bought two AVS carbs from ebay and planned to build one working unit out of them. First one that i got looked good overall and wasnt missing any parts. After i popped it open it was pretty obvious it had been sitting outside for some time and nothing could be done to save the internals(metering jets etc.). Second carb didnt look so good, covered with black hard burnt oil like stuff(inside as well) that hasnt reacted to any chemical that ive tried so far. Any good ideas guys?

 

Thanks for the tips, i bought couple hygrade rebuild kits to get started. Carb is/has been for a couple of weeks now soaked in diesel, without any visible progress. Seems like that black stuff has allmoust grown in to it. We do have carburator cleaning products here in Finland too, but as i can remember trying some brands years ago, they werent much of help(except lighting barbecue grill). Paint thinner might work, i dont think theres any rubber or plastic parts left in avs after i removed choke vacuum pot.
