What worse Arkie is when a carb comes in and someone removed one those plugs that the OEM doesn't sell them. I had to replace a Zama on a Stihl last year because the plug over the main was awol. It one those that Stihl has exclusive rights to.
Sometime you can file down a larger plug to fit but you got to be nearly perfect round for it to work.
I haven't blown any them out but have lost a few of those Nikki jets though due those bad o-rings. Glad I don't need replace them just because I need those tiny o-rings anymore. I hated having to wait on replacement jets that I could stock as there are so many different sizes.
You found out that is a problem so you know to be more careful from now on.
The truest measure of society is the how it treats its elderly, its pets, and its prisoners.
