Hi, I recently got an 86 gl-10. I put 2000 miles on it no problem. Lately, it started this thing after it warms up it starts chugging. Violently sometimes. After a while it stalls. If I let it sit for a few it'll drive for a while before starting its chugging again. I've ruled out fuel pump/filters. Are there any other parts I might change? Gentle I'm a noob. Thanks.
