there doesnt seem to be power coming from the engine or clutch.

 

Then you need to ask that problems to MFD(Modding for Dummies), it will help anything you want to solve. I cannot expect what mod do you want to make, but it will help. Search MFD and find discord link.

 

but this is the forum to ask modding questions

 

Yeah, but I think it is hard to get a answer for the mod on this forum so you need to go there: https://discord.gg/3Fy86de
