Well got a chance today to do some testing on my carb from my 925. I do have a question nailed down now. I seem to pass all the test but there is one instruction in this manual that confuses me a bit (yes...sometimes even I can be confused lol) A few things out of the way but it seems this manual is more about a walbro but I am assuming a tillotson checks the same way. It says to check metering side of diaphragm to build up pressure to 5-6 psi then depress the metering button. I do that and if I release immediately I will only drop pressure a little then hold but if I hold that down then I loose all pressure. I had the carb submerged and it looks to me when I hold it down all the bubbles come out of the center at the choke butterfly valve which would be the air flow into the carb which would be normal I would assume. Am I understanding this step correctly?
Thanks I just didn’t quite understand if when depressing the metering button if you press and release or press and hold it. Once I fixed the fuel line though it seems my carb repair was good afterall. This link under provided though is an excellent source it really helped me a lot. I still had a slight pressure loss over a long period of time like about 10 minutes and I think that was from around the needle but once fuel got wet it seemed to hold really well.
