I have been given a mower engine which I think is a Suffolk Super Colt (75G14-25A), I have spent many hours trying to get it to run. I think I have solved most of the problems but the carburetor is still causing me problems. I see on ebay there are replacement carbs for models 30 and later is there a replacement carb for the 25A?
The problem is that when I do manage to get it to start it will only run for a few seconds. The carburetor was badly corroded and every thing was seized, I have cleaned it out, heated it up and managed to free off adjusting screws and jet, flushed it through, fitted new gasket and set up per instructions The engine had been sat in a yard in all weathers, magneto/capacitor has been replaced and now has a good spark, points cleaned and adjusted.
This forum has been a mine of information regarding the carburetor but my patience is begging to run out, what are your thoughts please.
