Ok so called up Scrappys today to find out where my a9 is. Said they were still doing inventory on the parts but was told they would make sure to get mine out the door today, hopefully that happened. Still waiting for my #92 jet to come in, hopefully that will be the correct size, little bit confused because seems to be running lean but getting some back firing, thinking its just cause the a/f screw is almost all the way out and it's just not right cause of the wrong jet.
Where is a good place to start for picking a roller size on this setup? 7 or 8 gram?

So if I sometimes have to give it some throttle to get it started I probably could go up to a #38 pilot jet for easier starting?

Still trying to post up a picture of the spark plug, everytime I try it says web page not found, so not sure whats happening there. I am well below the max size. Still waiting for the #92 jet to come in.

Does having stronger torque and clutch springs affect your top end?

I have some written down somewhere that I did using an app on my old phone, I'll see if I can find it.

So I ordered a #92 main jet today so hopefully that will help. I've tried tuning the carb and the a/f mixture screw is pretty dang far out so that is set real rich which I believe also confirms I need a bigger jet. Also I've noticed that when letting off the throttle I'm getting a small backfire, it's not as loud as a normal one but I can definetly hear it, what causes backfires?

Ok, I'm thinking ill try a #92, also my current weights when I took them out weighed 5.6 grams, is 7grams a good starting point for this size engine now? Thinking it could be over revving.

Ok, no harm in running a slightly bigger jet then needed right? Just burns more gas right? Just my local shop charged me $17 bucks for the #  so don't wanna have to buy a bunch |

I believe the cam is in the right tooth. I am running a # jet. Will adding the a9 cam require a bigger jet then what I would need now? Cause I'm still waiting for the a9 from scrappys, just don't wanna get it right for this then put the cam in and need to re jet again |

All my parts seem to be excellent quality from them. Any ideas on if I need a bigger jet or can I fix this by adjusting the a/f mixture screw
