Only one crank seal isn't going to do it. They can harden up with age just sitting there.
It might be a carb issue but you don't know until both seals are new.
I do not know about the Ossa seals. Regardless, get them all replaced. You should see a remarkable difference. Keep in mind that you also want to insure no air leaks around the carb area either.
I thought the pilot jet to be too small. I'm running a 35 compared to his 20.
The lag from "no throttle" is just where the pilot jet is in effect. Lag could be that it's too lean.
Trying to contact Sammy Miller Products via email. I think they have a new site, but no email address listed. If someone has it can you PM me with it? Thanks!
Tear the carb down and report back with needle jet, main jet and pilot jet numbers. They are stamped on each part.
Instead of tape or "snuggest" of the carb to manifold a better test is to spray carb cleaner on the joint will the bike is running. A change in rpm denotes a leak.
It was more to show the components, like the spring and the thing that grabs the cable. And yes, the M49 is more comparable but it's three bikes deep. Isn't yours more handy?
