Hello, what is the best method for installing bearings into their race? I've set one in place and tapped it down until it was metal on metal. Is that sufficient? Surely it's not supposed to go into the race until flush? Also. does the coil spring on the seal go into carrier bearing housing not facing out? Thanks! 🙂 Seal goes in until flush correct?

Hi everyone, I received a 98 Yamaha Timberwolf from my brother for free, and I'm working on getting it going.
I am having the following problem:
The engine is backfiring through the carb.
I have done the following to try and get the four wheeler running:
Rebuilt the carb and set the air screw to 1-1/4 turn out and the circlip at middle position 3
Replaced the coil, because the cable was loose at the coil end
Repaired the main ground, coming from the battery
Replaced the ignition switch, because my brother couldn't find the key. New switch tested good
Tested the kill switch and it tested good
New coil tested goodfor both primary and secondary coils
Pickup coil resistance is at 195, which is correct
My source coil, is where I believe the issue is. The resistance is 310ohms, and it should be between 428-523ohms
When I opened the stator housing, there was significant oil, which I have read is normal. Does it sound like I'm on the right track replacing the source coil? Could this be causing my backfiring issue? It looks like the source coil is part of the stator assembly, is this correct? 4BD-85510-20-00 STATOR ASSY

The studs in the sprocket hub are stripped out. The hub is probably walloed out also. Probably will have to have a new sprocket hub. I doubt I have the ability nor the tools needed for this job. Thanks for all suggestions/opinions!

Hey all back again with my 1989 moto 4 250.
After putting a new carb on it it's really sputtery, it has new gas and I'm wondering what to tune on the carb to make it idle better. I've attached a video to describe the issue more. The bike is still work in progress but I think the video gets the point across. Thanks!
